Gum Arabic (GA), a safe dietary fiber known for its ability to modulate healthy gut microbiota and biocompatibility, is highly intriguing for coacervation with several classes of proteins. Coacervation between GA and proteins has gained significant interest for a range of food applications, particularly for encapsulation, emulsification, thermal stability, and sustained release of bioactive compounds. To date, the optimization process has preliminarily focused on pH and the biopolymer ratio. However, this alone is not sufficient to determine the strength of interactions and functionality. This review evaluates the conditions under which GA complexes with proteins, focusing on modifications in conjugation methods and structural changes in GA or proteins that enhance electrostatic interactions and improve functionality. The review highlights the potential of unexplored modified GA, which could improve coacervation with proteins, and explores its possible food applications, such as encapsulation and sustained release of bioactives, probiotic viability, edible packaging, 3D-printed foods, shelf stability, and gummy candies, illustrating the future growth of GA-based coacervates. It also addresses the digestibility, safety, regulations, limitations, and future prospects of GA-protein coacervates. In conclusion, the enhanced complexation of highly compatible GA with food proteins suggests promising scalability for various food products.

In this paper we discuss the latest developments in colloidal plasmonics, a field with over a century of history, applied to the biomedical sector. Emphasis is placed on the nanoarchitectonic nature of plasmonic systems that can be used for sensing, drug delivery and manipulation of biomolecules. For instance, quantum effects linked to plasmonic phenomena are being used to enhance monitoring of chiral particles and their interaction with light, which is essential for the pharmaceutical industry in reaching the required enantiopurity in some drugs. In diagnostics, radiofrequency waves can excite surface plasmon resonance through amplified photoacoustic effects, thus permitting thermo-acoustic imaging. An example of enhanced therapy was introduced in carefully designed nanoarchitectures where a multi-branched gold nanooctopus was surrounded by a mesoporous polydopamine and loaded with ribonucleoproteins for the target delivery into tumor cells. Moreover, the longstanding challenge of heating due to Ohmic losses, which has hindered the use of plasmonic tweezers for manipulating biologically relevant analytes, is now being exploited for enhanced trapping, manipulation, and transport of cells and other biological particles. The combination of magnetic materials and plasmonic colloids in the realms of magnetoplasmonics can also be explored in sensing and enhanced drug delivery, which further exemplifies the versatility of nanoarchitectonics.

Exosomes are naturally occurring nanocarriers derived from various cells. In recent years, they have attained significant attention for their potential in precise drug delivery and therapeutic applications. Exosomes exhibit several advantages, remarkably improved stability, bioavailability, and delivery efficiency, which are further augmented by integration with nanomaterials. Functionalizing the aptamer and nanomaterial on the exosomal surface significantly improves the binding affinity and specificity. Here in this review, we examine the synergistic therapeutic effect of exosome-nanomaterial-aptamer conjugate with particular attention to their uses in cancer therapy, bone fracture regeneration, wound healing, etc. Recent advances in the field demonstrated that the amalgamation of different nanomaterials, aptamers, and exosomes has proven to be a transformative approach in the field of therapeutics. Here in the nanocomposite, the aptamer is exclusively used as a recognition molecule to provide specificity to the target cells. Exosomes serve as biocompatible nanocarriers, and different nanomaterials (AuNPs, AuNRs, SiNPs, Graphene, etc.) complement the therapeutic efficiency by PTT/PDT/ROS generation/SO generation, etc. Briefly, the above-mentioned nanocomposite serves as the perfect therapeutic agent by utilizing the exosome's biocompatibility, aptamer's high affinity and nanomaterial's multifunctionality. Furthermore, the challenges and limitations of this nanocomposite have been discussed, along with its prospects in clinical practices.

Carbyne, a one-dimensional carbon allotrope characterized by sp1 hybridization, has attracted significant attention due to its unique structure and exceptional properties. In principle, carbyne is an infinite linear carbon chain, or a long linear carbon chain that its properties remain independent of its length. Despite being proposed a century ago, the existence of carbyne has been a subject of controversy, primarily because of its extreme instability and strong chemical reactivity. So far the longest end-capped polyyne and the carbon nanotube-confined linear carbon chain comprise up to 68 and 6000 carbon atoms, respectively. In this review, general synthesis methods for confined linear carbon chains, i.e., confined carbyne, are outlined, with a particular focus on the chronological development of routes towards carbyne. In addition, the structure and properties of the carbon chains unraveled by theoretical calculations and various Raman spectroscopy are discussed in detail. Finally, the current challenges in the synthesis and property-engineering of sp1-hybridized carbon but not limited to confined carbyne are addressed, offering insights into potential future directions for both fundamental research and applications.

Pharmaceuticals and personal care products (PPCPs) are a newly identified category of emerging global pollutants often found in aquatic systems. Efficient removal of these pollutants from the water/wastewater is currently problematic because of their low biodegradability and high hydrophilicity, as well as their distinct physicochemical features and lower concentrations. Materials of Institut Lavoisier (MIL), Zeolitic imidazolate framework (ZIF), and University of Oslo (UiO) are highly engineered metal-organic frameworks (MOFs) composed of unique components necessary for the formation of crystals with exceptional porosity, large surface areas, large pore sizes, crystalline structures, tunable properties, excellent chemical and thermal stability for environmental remediation. This study provides detailed and combined applications of UiOs, MILs, and ZIFs as adsorbents for capturing the new class of emerging pollutants (PPCPs) from the liquid phase. MOFs as ideal candidates for PPCP decontamination were discussed, followed by the MOF porosity and factors that affect MOF stability. Various synthetic approaches for MILs, ZIFs, and UiOs were discussed, as well as their corresponding pros and cons. An in-depth performance of these three MOFs for adsorptive removal of PPCPs from the liquid phase was discussed, assessing the state-of-the-art for specific applications and the effectiveness of UiOs, MILs, and ZIFs as adsorbents for PPCP decontamination . The unique performance garnered from the study provided a way forward/potential for real-life/practical applications of these sorbents and insight into corresponding mechanisms and synergistic relationships. To foster the advancement of the field, viable shortcomings and strengths associated with these novel classes of MOFs, treatment options, and knowledge gaps to explore specific research directives for large-scale or industrial-scale applications were highlighted.

Diverse collectors are employed in mineral flotation; they are categorized into distinct families distinguished by a particular characteristic that enables their adsorption onto a given mineral. All these collectors are designed to increase the hydrophobicity of a mineral's surface to improve its floatability and separation in the froth flotation process. Phosphate ore enrichment using flotation has long utilized anionic collectors in the form of synthetic fatty acids derived from petrolic raw materials. This nonrenewable material has several disadvantages, including lack of biodegradability, possible toxicity and difficult conditions of use. This paper aims to explore the effect of eco-friendly and promising alternatives that can substitute the conventional collectors and introduce some new non-toxic reagents into the flotation additives industry. For this purpose, the different compounds used as biobased collectors are examined and their performance is evaluated, relying on some fundamental studies and flotation tests. The adsorption behavior and efficiency of these compounds are assessed based on the analysis of previous zeta potential measurements, Fourier transform infrared spectra, adsorption tests, contact angle determinations, and flotation test findings. Selectivity of the collector is a key factor in determining the effectiveness of this reagent. Therefore, this review discusses the main factors affecting the selectivity of biobased collectors toward phosphate ore minerals. Additionally, the different strategies to improve this selectivity are emphasized. Lastly, a comparison of the performance of biobased collectors to conventional reagents is established with the aim of determining their main advantages and disadvantages.

Porous covalent organic frameworks (COFs) are promising materials used for separation and purification during environmental remediation. This critical review focuses on two key aspects. First, it critically examines strategies to improve COF design and structure and evaluates their impact on separation performance. Second, engineering approaches for enhancing the interactions between COF-based adsorbents and metals for enhanced separation and capture are elucidated. The latest body of research on separating metals (e.g., Li, K, Sr, Hg, Cd, Pb, Cr, Au, Ag, Pd, and U) using COF-based adsorbents is discussed to understand the factors that influence their performance. However, it is to be noted that COF-based adsorbents are still in their infancy and remain largley unexplored, mainly hindered by synthetic complexities and suboptimal crystalline structures. This highlights the need for further research and development to fully unlock the excellent potential of COFs for metal separation applications, particularly in environmental and energy applications.

Hydrogen-bonded organic frameworks (HOFs) are widely used in environmental and energy fields because of their high crystallinity, solution processability, and easy regeneration. Although there have been some reviews focusing on the specific environmental or energy applications of HOFs, a comprehensive research summary and analysis of research trends across the entire field is still lacking. To facilitate the advancement of HOFs, a bibliometric analysis method was used to examine all relevant literature on the subject. Initially, the general bibliometric distribution of the dataset by year, country, institute, reference source, and research focus are determined. Subsequently, the research hotspots covering adsorption, separation, sensing, catalysis, and energy storage are thoroughly explored. To conclude, an analysis of the potential opportunities and obstacles that lie ahead for HOFs is presented, offering a novel perspective to propel their advancement in the fields of environmental remediation and energy utilization.

Recent advances in computational capabilities have revolutionized the modeling of nanoporous carbons, enabling a transition from idealized pore descriptions to versatile three-dimensional molecular models. This review traces the evolution from traditional continuous potential methods and simple pore models to modern simulation techniques that generate realistic carbon structures incorporating surface heterogeneity, pore connectivity, and framework flexibility. We examine various approaches including Hybrid Reverse Monte Carlo, Quench Molecular Dynamics, and Annealed Molecular Dynamics methods, discussing their respective strengths and limitations. Particular attention is given to the choice of interatomic potentials and their impact on structural predictions. The development of million-atom models captures long-range ordering effects previously inaccessible to simulation. Applications of the 3D models demonstrate their ability to quantitatively predict adsorption behavior and provide the improved characterization of practical carbons using novel methods such as 3D-VIS and APDM. Recent hybrid MD/MC approaches, which incorporate the effects of structure flexibility, offer new insights into adsorbate-induced structural changes. This review highlights how advancing computational methods are bridging the gap between molecular-level understanding and practical applications in the carbon materials design and modeling of adsorption processes.
