Fluorescence-based probes and sensors have emerged as indispensable tools for the detection of alkaline phosphatase (ALP), a clinically significant enzyme, owing to their high sensitivity, real-time imaging capabilities, and superior spatial resolution. This review examines fluorescence-based ALP detection techniques published between 2020 and 2025 and divides them into three main categories, which are small-molecule fluorogenic probes, nanomaterial-based fluorescent sensors and nucleic acid-assisted hybrid systems. In this context, particular attention is given to the structural evolution of various fluorophore scaffolds and the engineering of molecular dye platforms designed to modulate specific photophysics for enzyme-responsive signaling. By utilizing cutting-edge design components like near-infrared and ratiometric fluorophores, nanoparticle-based signal amplifiers, and deoxyribonucleic acid/ribonucleic acid (DNA/RNA)-mediated amplification circuits (including aptamer and clustered regularly interspaced short palindromic repeats (CRISPR)-driven mechanisms), researchers have improved analytical performance across these platforms. A wide range of applications, such as clinical diagnostics (ultrasensitive serum assays), live-cell and in vivo imaging of enzyme activity, environmental monitoring, and high-throughput screening. These advances have enabled applications ranging from ultrasensitive serum assays to live-cell imaging and portable readouts. This review highlights the increasing significance of fluorescence-based ALP detection in analytical chemistry and biomedicine by showcasing both state-of-the-art probe design and practical deployment. It also explores how current developments are laying the groundwork for next-generation ALP sensors with even higher sensitivity, specificity, and versatility. In addition to summarizing recent reports, we benchmark the 2020–2025 literature against pre-2020 ALP sensing paradigms to delineate genuine step-changes and to highlight persistent limitations that remain unresolved. Lastly, it discusses the opportunities and challenges that still need to be overcome before these ALP sensing technologies can be used in clinical and field settings.

基于荧光的探针和传感器由于其高灵敏度、实时成像能力和优越的空间分辨率，已成为检测碱性磷酸酶（ALP）（一种临床重要酶）不可或缺的工具。本文综述了2020年至2025年间发表的基于荧光的ALP检测技术，并将其分为三大类，即小分子荧光探针、基于纳米材料的荧光传感器和核酸辅助混合系统。在此背景下，特别关注各种荧光团支架的结构演变和分子染料平台的工程设计，以调节酶反应信号的特定光物理。通过利用先进的设计组件，如近红外和比例荧光团，基于纳米颗粒的信号放大器和脱氧核糖核酸/核糖核酸（DNA/RNA）介导的扩增电路（包括适配体和聚集规律间隔短回文重复（CRISPR）驱动机制），研究人员提高了这些平台的分析性能。广泛的应用，如临床诊断（超灵敏血清测定），活细胞和体内酶活性成像，环境监测和高通量筛选。这些进步使得从超灵敏血清检测到活细胞成像和便携式读数等应用成为可能。这篇综述通过展示最先进的探针设计和实际部署，强调了基于荧光的ALP检测在分析化学和生物医学中的日益重要的意义。它还探讨了当前的发展如何为具有更高灵敏度、特异性和通用性的下一代ALP传感器奠定基础。除了总结最近的报告外，我们还将2020-2025年的文献与2020年前的ALP感知范式进行比较，以描述真正的阶梯变化，并强调仍未解决的持续限制。最后，讨论了在这些ALP传感技术应用于临床和现场环境之前仍然需要克服的机遇和挑战。

The preparation of different green-bluish copper pigments via synthetic routes is reported in several treatises, from antiquity to the beginning of 19th century. The most famous preparation is the one for the production of verdigris, a bright green pigment resulting from the corrosion of pure copper plate by vinegar. The recipes are numerous, and many differences in terms of ingredients and procedures emerge from a comparative study. Such a variety of preparations corresponds to a chemical variety. Many works have already investigated such systems with the most common spectroscopic techniques (e.g., ATR-IR, Raman, etc.). However, recently the Electron Paramagnetic Resonance (EPR) spectroscopy has emerged as a new tool for the investigation of these pigments, since new and more complete information on the chemistry of such systems can be gained. In this work, three different recipes have been selected as more representative, reproduced, and characterized with EPR, micro-ATR-IR and micro-Raman spectroscopies. Our experiments highlight the advantages in the use of EPR, with respect to simple Raman and IR investigations. In particular, the EPR spectroscopy evidenced the presence of different bimetallic and monometallic species in the samples, allowing us to differentiate and characterize the Cu(II)-complexes among the studied samples.

从古代到19世纪初，有几篇论文报道了通过合成路线制备不同的绿蓝色铜颜料。最著名的制备方法是生产铜绿，这是一种明亮的绿色颜料，由纯铜板被醋腐蚀而产生。食谱种类繁多，通过比较研究，在配料和制作过程上出现了许多差异。这种不同的制剂对应于不同的化学物质。许多工作已经用最常见的光谱技术（例如，ATR-IR，拉曼等）研究了这样的系统。然而，最近电子顺磁共振（EPR）光谱已经成为研究这些颜料的一种新工具，因为可以获得这些系统的新的和更完整的化学信息。在这项工作中，选择了三种不同的配方作为更具代表性的，用EPR，微atr - ir和微拉曼光谱进行了再现和表征。我们的实验突出了使用EPR的优势，相对于简单的拉曼和红外研究。特别是，EPR光谱证明了样品中存在不同的双金属和单金属物种，使我们能够区分和表征所研究样品中的Cu(II)-配合物。

Two low molecular weight gelators based on α-cyanostyrene derivatives (DPAE and DNAE) were designed and synthesized via Knoevenagel condensation reaction. Both DPAE and DNAE could be self-assembled into gels with diverse colors in different solvents, and fibrous band and smooth film structures were formed. Interestingly, the gelation ability, self-assembly structures, surface wettability, fluorescence emission behaviors and functions of them could be regulated by their sizes of conjugate structure. DNAE could selectively detect hypochlorite with the limit of detection of 0.19 μM. The detection of hypochlorite can be operated over a wide pH range of 3.5–10.8. Fatty alcohol could be sensitively sensed by DNAE in hexane and petroleum ether. This work will provide new idea of design and construction multi-functional supramolecular self-assembly materials.

通过Knoevenagel缩合反应，设计并合成了两种基于α-氰苯乙烯衍生物（DPAE和DNAE）的低分子量凝胶。DPAE和DNAE均可在不同溶剂中自组装成不同颜色的凝胶，并形成纤维带和光滑的膜结构。有趣的是，它们的凝胶能力、自组装结构、表面润湿性、荧光发射行为和功能都可以通过共轭结构的大小来调节。DNAE可选择性检测次氯酸盐，检出限为0.19 μM。次氯酸盐的检测可以在3.5-10.8的宽pH范围内进行。DNAE对正己烷和石油醚中的脂肪醇具有灵敏的感知能力。本研究将为设计和构建多功能超分子自组装材料提供新的思路。

Heparin (Hp), a highly negatively charged polysaccharide, plays a key role in regulating blood coagulation and is widely used as an anticoagulant in clinical settings. However, its use demands precise monitoring to avoid complications that arise from its excessive levels. To address this, there is a pressing need for a rapid, label-free, and straightforward method to accurately measure heparin concentrations. In this study, we developed a novel fluorometric sensing technique using Benzothiazoliun based BODIPY derivative (BTB) for precise Hp detection. Upon interaction with polyanionic Hp through strong electrostatic interaction, BTB forms aggregates, which diminish the photoemission efficiency of the dye to a significant extent. The change in emission intensity at ∼593 nm for BTB produces a fluorometric signal with a linear response up to 3.7 μM of Hp, allowing detection of Hp down to 12.03 nM in water. This optical response has been found to be highly specific to Hp, unaffected by other potential interferents in complex biological matrices, making it a reliable tool for Hp quantification in biofluids such as fetal bovine serum (FBS) and human urine with excellent efficiency. Furthermore, the BTB-Hp system is highly sensitive to the ionic strength of the medium, enabling its use in detecting protamine (Pr) down to 6.85 nM via fluorescence “Off-On” method. This fluorometric approach ensures high accuracy due to its reproducibility, resistance to environmental variations, and applicability over a broad pH range. Detailed spectroscopic studies along with quantum chemical calculation reveal the sensing mechanism of heparin and protamine, opening new possibilities for advanced biosensing applications.

肝素（Hp）是一种带高度负电荷的多糖，在调节血液凝固中起着关键作用，在临床中被广泛用作抗凝剂。然而，它的使用需要精确的监测，以避免因其过量而引起的并发症。为了解决这个问题，迫切需要一种快速、无标签、直接的方法来准确测量肝素浓度。在这项研究中，我们开发了一种新的荧光传感技术，使用基于苯并噻唑啉的BODIPY衍生物（BTB）来精确检测Hp。BTB与聚阴离子Hp通过强静电相互作用形成聚集体，极大地降低了染料的发光效率。BTB在~ 593 nm处的发射强度变化产生了线性响应高达3.7 μM of Hp的荧光信号，允许在水中检测低至12.03 nm的Hp。这种光学响应已被发现对Hp具有高度特异性，不受复杂生物基质中其他潜在干扰的影响，使其成为生物液体（如胎牛血清（FBS）和人类尿液）中Hp定量的可靠工具，效率极高。此外，BTB-Hp系统对介质的离子强度高度敏感，使其能够通过荧光“Off-On”方法检测低至6.85 nM的鱼精蛋白（Pr）。由于其可重复性，对环境变化的抵抗力以及在广泛的pH范围内的适用性，这种荧光测定方法确保了高精度。详细的光谱研究以及量子化学计算揭示了肝素和鱼精蛋白的传感机制，为先进的生物传感应用开辟了新的可能性。

Herein, a series of four chiral-amide-bonded anthracene-porphyrin hybrids and six of their metallocomplexes (M = Ni, Mn, Zn) were prepared and characterized. When the chiral L/d-alanine and/or L/d-phenylalanine units were introduced, the chiral-optical responses were clearly observed in the soret-band of porphyrins and their metallocomplexes. In addition, the UV-light-controlled [4 + 4] cycloaddition reactions of anthracene substituents could be facilely achieved and the photo-dimers were confirmed. More interestingly, the transformation speed of UV-light-controlled [4 + 4] cycloadditions were also modulated by chiral linkages and/or metal-centers, and the extension of chiral-optical responses were observed at the [4 + 4] cycloaddition dimer regions.

The rational design of hole transport materials (HTMs) through precise molecular energy level modulation and enhanced interfacial coupling, offers a promising approach for improving perovskite solar cells (PSCs) performance. In this study, we designed and developed three novel acridine-derivative HTMs, termed as TAO, TAS, and TASO2, featuring tailored highest occupied molecular orbital (HOMO) energies and strengthened interfacial interactions with the perovskites layer. The TAS-based device obtained a champion power conversion efficiency (PCE) of 25.6% and demonstrated outstanding environmental stability. These results highlight the crucial role of optimized energy level alignment and interfacial passivation in designing efficient and stable HTMs for perovskite photovoltaics.

In order to fully utilize solar energy through photosensitive organic materials, the most effective method is to increase the effective conjugation degree of molecules for expanding their absorption spectrum; however, this strategy is usually accompanied by complex synthesis and processing difficulties. Here, we propose a new strategy for utilizing the strong intermolecular interactions of simple cationic-radical materials to construct a tighter stacking pattern in the aggregated state, thereby broadening the absorption coverage. By stepwise diminishing the steric hindrance of cationic radicals/counteranions in phenazine-cationic radicals, DMPZ-I exhibits the tightest stacking structure among the three derivatives, with an absorption spectrum broadened to 1500 nm and a cationic radical molecular weight of merely 210.1 g/mol. Moreover, DMPZ-I with the tightest radical-based π-aggregates exhibits remarkable photothermal characteristics and significant antibacterial properties against Staphylococcus aureus.

为了通过光敏有机材料充分利用太阳能，最有效的方法是增加分子的有效共轭度，扩大其吸收光谱；然而，这种策略通常伴随着复杂的合成和加工困难。在这里，我们提出了一种新的策略，利用简单阳离子-自由基材料的强分子间相互作用，在聚集状态下构建更紧密的堆叠模式，从而扩大吸收覆盖范围。通过逐步降低芬那嗪-阳离子自由基中阳离子自由基/反阴离子的位阻，dmpz - 1具有最紧密的层叠结构，吸收光谱扩大到1500 nm，阳离子自由基分子量仅为210.1 g/mol。dmpz - 1具有最紧密的自由基基π-聚集体，具有显著的光热特性和对金黄色葡萄球菌的抗菌性能。

The prime objectives of this research are to synthesize strontium ferrite (SrFe₂O₄) magnetic nanoparticles (MNPs), to determine their photocatalytic activity on the Congo red dye, as well as their antibacterial activity. The factors of photocatalytic activity were optimized using Response Surface Methodology (RSM). SrFe₂O₄ MNPs were synthesized using the sol-gel auto-combustion process and subsequently characterized by XRD, XPS, VSM, and UV–Vis diffuse reflectance spectroscopy. The photocatalytic activity was determined under visible light at varying dye concentrations, catalyst dosages, pH levels, and reaction times. RSM (Box-Behnken) design was used to simulate process optimization. Antibacterial activity was determined using the agar well-diffusion method with selected Gram-positive and Gram-negative bacteria, while toxicity was assessed by the Microtox® assay. Likewise, SrFe₂O₄MNPs obtained were found to possess a well-formed crystalline hexagonal morphology and exhibited a narrow size distribution of about 20–30 nm,and were found to possess band gap energies of about 2.03 eV and were also ferromagnetic, allowing for easy magnetic separation. Completely 100 % degradation of CR was achieved under visible light at the optimized conditions. The excellent stability of the photocatalyst, coupled with a 82.6% degradation efficiency, was observed even after five consecutive cycles. In addition, SrFe₂O₄ MNPs exhibited potent bacteriostatic activity, with inhibition zones of approximately 31 mm in a dose-dependent response against E. coli, and a relatively low toxicity, even after undergoing the dye degradation process, as confirmed by the toxicity assessment. Such promising findings declare that SrFe₂O₄ MNPs are an effective, recyclable, and ecologically safe photocatalyst that is active in visible light, with additional superior antibacterial properties, thereby highlighting their relevance in sustainable wastewater management.

本研究的主要目的是合成锶铁氧体（SrFe2O4）磁性纳米颗粒（MNPs），并测定其对刚果红染料的光催化活性以及抗菌活性。采用响应面法（RSM）对影响光催化活性的因素进行了优化。采用溶胶-凝胶自燃烧法合成了SrFe2O4 MNPs，并用XRD、XPS、VSM和UV-Vis漫反射光谱对其进行了表征。在可见光下测定了不同染料浓度、催化剂用量、pH值和反应时间下的光催化活性。采用Box-Behnken设计模拟工艺优化。选择革兰氏阳性菌和革兰氏阴性菌，采用琼脂孔扩散法测定抗菌活性，采用Microtox®法评估毒性。同样，获得的SrFe2O4MNPs具有良好的六方晶体形态，尺寸分布约为20-30 nm，带隙能约为2.03 eV，并且具有铁磁性，易于磁分离。在可见光条件下，CR的降解率达到100%。在连续5次循环后，光催化剂仍具有良好的稳定性和82.6%的降解效率。此外，SrFe2O4 MNPs表现出强大的抑菌活性，对大肠杆菌具有约31 mm的剂量依赖性抑制区，并且毒性相对较低，即使经过染料降解过程，毒性评估证实了这一点。这些有希望的发现表明，SrFe2O4 MNPs是一种有效的、可回收的、生态安全的光催化剂，在可见光下具有活性，具有额外的优越抗菌性能，从而突出了它们在可持续废水管理中的相关性。

The tetracycline (TC) residue poses a significant threat to the safety of animal–derived food. Coordination–sensitized luminescence is a common method for detecting TC, but this approach relies on single–channel fluorescence, which is less resistant to interference and causes false detection. To improve detection accuracy, a coordination–sensitized dual–channel fluorescence probe was here developed for TC based on the complex of an AIE dye (xylenol orange, XO) with Zn²⁺. After adding TC to the complex, TC and XO were bridged by the coordination of Zn²⁺ to form a ternary complex. In the ternary complex, the green emission of TC at 520 nm was sensitized owing to the coordination of TC with Zn²⁺, and the red emission of XO at 600 nm was also sensitized because TC limited the rotation of XO. The dual–channel sensing property of the complex exhibited the advantage of the self–validation effect, avoiding false results and improving detection accuracy. The complex also displayed the merits of simple preparation (one–step synthesis at 25 °C), low detection limits (channel 520 nm: 6.7 nM, channel 600 nm: 12.9 nM) and short response times (channel 520 nm:10 s, channel 600 nm: 10 s). The complex was applied to determine TC in milk, honey and pork samples, and combined with a smartphone to facilitate visual dual–channel detection of TC. This work introduces Zn²⁺ and an AIE dye as two coordination–sensitized luminescence sites for dual–channel detection of TC, providing a reliable tool to analyze TC in animal–derived food.

四环素残留严重威胁着动物源性食品的安全。配位敏化发光是检测TC的常用方法，但这种方法依赖于单通道荧光，对干扰的抵抗能力较差，容易导致误检。为了提高检测精度，本文基于AIE染料（二甲酚橙，XO）与Zn2+的配合物，研制了一种配位敏化的双通道荧光探针。在配合物中加入TC后，TC和XO通过Zn2+的配位桥接形成三元配合物。在三元配合物中，由于TC与Zn2+的配位作用，TC在520 nm处的绿色发光被敏化；由于TC限制了XO的旋转，XO在600 nm处的红色发光也被敏化。该配合物的双通道传感特性表现出了自验证效应，避免了假结果，提高了检测精度。该配合物还具有制备简单（25℃一步合成）、检测限低（520 nm通道6.7 nm、600 nm通道12.9 nm）、响应时间短（520 nm通道10 s、600 nm通道10 s）等优点。该配合物应用于牛奶、蜂蜜和猪肉样品中的TC检测，并与智能手机结合，实现了TC的视觉双通道检测。本研究引入Zn2+和AIE染料作为双通道检测TC的两个配位敏化发光位点，为分析动物源性食品中的TC提供了可靠的工具。

In this study, tetra 4-(4-fluorophenyl)-5-(furan-2-yl)-4H-1,2,4-triazole-3-thio substituted Co(II) phthalocyanine was synthesized from novel, 4-((4-(4-fluorophenyl)-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)phthalonitrile, compound by microwave irradiation. The novel compounds were characterized by FT-IR, ¹H NMR, ¹³C NMR, mass spectrometric and elemental analysis methods. The electrochemical and in-situ spectroelectrochemical properties of CoPc are determined. During the reduction process, one quasi reversible metal-based and one reversible phthalocyanine-based redox couple were observed. 4-(4-fluorophenyl)-5-(furan-2-yl)-4H-1,2,4-triazole-3-thio- substituent included CoPc electropolymerized on indium tin oxide (ITO) glass electrode. Electrochromic performance of Poly(CoPc) film was recorded with in-situ spectroelectrochemical measurements. The effect on optical contrast thickness of film, solvent and supporting electrolyte was investigated. The color of Poly(CoPc) film changed from green to brown color at 1.40 V and optical contrast was recorded as 34 % at 690 nm in DCM/TBAPF₆ electrolyte. In addition, coloring/bleaching time was recorded as about 10 s.
