Small extracellular vesicle (sEV) also known as exosome carries of intercellular information and genetic material transfer, e.g., DNA, RNA, proteins, lipids, and other active substances. However, conventional detection techniques do not meet the requirements of sEVs analysis. Recently, electrochemiluminescence (ECL) biosensors have become powerful tools in the detection of sEVs owing to their attractive properties with identification strategies and unique potential- and spatial-controlled ability. Therefore, in this review, the latest advances and principal issues in the ECL biosensors for sEV detection are systematically discussed. Especially, the sensing mechanisms and signal transduction strategies involved in sEV identification are discussed in detail to provide insights into the design and construction of ECL biosensors, such as DNA logical computation, proximity labeling, proximity ligation assay, mediated-membrane fusion strategy, lab-on-a-chip systems, as well as artificial intelligence. Subsequently, the recent application of ECL biosensors for clinic sEV diagnosis is further emphatically introduced, including tumorous sEV identification, peritoneal metastasis diagnosis, tumor microenvironment monitoring, phenotypic profiling, and asthma evaluation. Finally, the potential challenges and future directions of sEV sensing systems are highlighted. It provides a distinct perspective for researchers to construct ECL biosensors and enlightens the fast development of sEV detection in biological research, clinical use, and commercialization.

Plant diseases have significant adverse impacts on the food security and biodiversity, making effective diagnosis extremely essential for efficient and sustainable plant disease management. Clustered regularly interspaced short palindromic repeats (CRISPR) and the CRISPR-associated protein (Cas)-based systems have emerged as powerful tools for detecting plant pathogens, due to their fast speed, and excellent accuracy. However, a comprehensive systematic review of the application of CRISPR/Cas in plant disease diagnosis is lacking, which partially hampers the practical application. This review firstly discusses the underlying principles of CRISPR/Cas-based biosensing technology. Then it highlights the significant applications in detecting plant viruses, bacteria, and fungi. Finally, it provides insightful analysis and predictions regarding the future development of the CRISPR/Cas system for diagnosing plant diseases. This review not only contributes to the advancement of plant disease diagnosis technology based on the CRISPR/Cas system, but also offers inspiration for smart plant protection and precision agriculture.

Single-molecule detection and imaging have provided a powerful toolbox for exploring the molecular basis of life. In contrast to conventional ensemble measurements, single-molecule detection technique can directly observe and investigate the properties, behaviors, and interactions of individual molecules at the molecular level. The capability of measuring single biomolecules with good specificity and high accuracy is of great importance in biosensing, bioimaging, biomedical research and diseases diagnosis. Single-molecule detection technique can be used for characterizing and measuring various biomarkers due to its unique advantages of high resolution, ultrahigh sensitivity, visualization capability, and minimal sample consumption. Herein, we review the recent advance in fluorescence-, electrochemiluminescence- and surface-enhanced Raman scattering (SERS)-based single molecule detection and imaging for sensitive measurement of nucleic acids, proteins, viruses, living cells, and exosomes in clinical samples. We summarize the working principles and applications of these technologies, and discuss the current challenges and future perspectives in this field as well.

Aflatoxin and its metabolites have posed a significant threat to human health as carcinogens. Sensitive detection of aflatoxins is demanded in food safety, environmental monitoring, and risk assessment. Over the past a few decades, aptamers have attracted wide interests, which can be in-vitro selected and bind with targets. Aptamer-based sensors, particularly for aflatoxins detection, have become powerful tools due to their high-affinity specific binding. In this review, we summarize recent developments of typical aptasensors for the quantification of aflatoxins, especially for aflatoxin B1, including colorimetric, electrochemical, chemiluminescence, fluorescence, surface plasmon resonance (SPR), and surface-enhanced Raman scattering (SERS) sensors, with particular emphasis on aptamer binding mechanism, and various sensor designs as well as analytical performance, etc. Finally, the advantages and disadvantages of these aptasensors and their development prospects are discussed.

Popularization of green analytical chemistry (GAC) encouraged miniaturization of sample preparation scale – with preference to microextraction scale methods and automation by platforms to achieve high throughput, reduce energy costs, minimize hazardous chemical disposal, and shorten extraction time. It improves the sample throughput, extraction efficiency, sensitivity, reproducibility, and greenness of the developed method. To achieve these objectives, automatic platforms for high-throughput liquid-phase microextraction (LPME) and solid-phase extraction/microextraction (SPE/SPME) were developed. Among the reported platforms, the 96-well plate, pipette tip, lab-in-syringe (LIS), and microfluidic devices receive significant attention. This review describes the advantages of each platform with respect to green chemistry principles. In addition, the challenges associated with each platform are critically evaluated. Moreover, the review highlights how the use of these platforms can minimize waste disposal, energy consumption, and reduce the hazardous effects. Furthermore, a comparative assessment of the above mentioned platforms in terms of green microextraction techniques has been discussed.

The detection of biomarkers can timely detect abnormalities and provide appropriate treatment for patients, which effectively improves the prognosis of the disease. Interstitial fluid (ISF) contains a variety of biomarkers similar to other body fluids. The detection of biomarkers in ISF can not only reflect the physiological and pathological changes in the body immediately but also reduce the physical harm to patients. Nanomaterials are low-cost, more stable, easy-preparation, and less susceptible to environmental factors, which have similar catalytic activities and electrochemical properties. Through the combination of nanomaterials with ISF analysis, it can successfully achieve minimally-invasive detection of biomarkers, which not only improves the accuracy and sensitivity of detection but also significantly reduces patient suffering. The non-enzymatic detection methods for biomarkers in ISF play a crucial role in the early diagnosis of diseases, especially diabetes, renal disease, and cardiovascular disease, which will hold implications for the development of future clinical diagnosis.

DNA is much continuously exposed to endogenous and exogenous agents that induce damage, potentially leading to genomic instability, disease development, and aging. Detecting DNA damage and understanding associated repair mechanisms are essential for advancing diagnostic techniques, biosensors, and therapeutic interventions. Since DNA damage varies, the desired measurement approach differs, highlighting the need for an unbiased exploration of DNA damage biomarkers, along with a critical analysis of various quantification methods. Therefore, this review aims to provide a comprehensive overview of current methodologies for measuring DNA damage, focusing on direct detection of DNA lesions and indirect measurement of repair enzymes. We discuss various analytical, biochemical, and imaging techniques, identify the limitations in existing technologies and suggest future directions. This review emphasizes the growing need for advanced tools to measure DNA damage, which is set to play a transformative role in early disease detection, optimizing treatments, and supporting safe human space exploration.

Halloysite nanotubes (HNTs), naturally occurring aluminosilicate clay minerals, possess unique structural and physicochemical properties that make them highly promising sorbents for solid-based extraction methods. Their tubular structure, high surface area, and inherent adsorption capacity enable efficient capture of analytes from complex matrices. This review comprehensively examines the application of HNTs in solid-phase extraction (SPE) and its miniaturized variants, such as solid-phase microextraction (SPME) or micro SPE (μ-SPE), focusing on their use in isolating analytes from environmental, beverage, food, and biological samples. Key aspects covered include the synthesis and modification of HNT-based composites to enhance extraction selectivity and efficiency, the assessment of the environmental impact and greenness of the extraction methodologies, and the characterization techniques used to elucidate the structure-property relationships of the HNT-based materials. The review highlights the significant potential of HNTs to advance sample preparation technologies by offering sustainable and efficient extraction processes across a broad range of analytical disciplines.
