Background: For the nanoparticulate system and the transportation of cellular elements for the fabrication of microelectronic devices, self-assembled nanoclusters arrange the components into an organized structure. Nanoclusters reduce transcytosis and increase endocytosis in intestinal mucin to strengthen the retrograde pathway that helps for delivery of actives to the Golgi apparatus.
Objectives: This review article focuses on the self-assembled nanoclusters for cellular transportation, applications of self-assembled structures in the delivery of essential elements like using a peptide in targeted and stimuli-responsive drug delivery systems, and self-assembly of tocopherol nanoclusters that promote vitamin E delivery across the endothelial barrier.
Methods: Current innovation in the self-assembly of peptides includes the formation of nanostructures like vesicles, fibers, and rod-coil in various applications of wound healing, tissue engineering, atherosclerosis treatment, sensing heavy metals from biological and environmental samples, and advanced drug delivery.
Results: Self-assembled biodegradable nanoclusters are used as biomimetic structures for a synergistic effect. For temperature-triggered drug release nanoclusters, modifications in preparation methods, such as the inclusion of a copolymer, are made.
Conclusion: Green synthesis of nanoclusters, nanocluster-based biosensors, and artificial intelligence are future concepts in the manufacturing and prevention of toxicity in humans.

The increase in computational power demand led by the development of Artificial Intelligence is rapidly becoming unsustainable. New paradigms of computation, which potentially differ from digital computation, together with novel hardware architecture and devices, are anticipated to reduce the exorbitant energy demand for data-processing tasks. Memristive systems with resistive switching behavior are under intense research, given their prominent role in the fabrication of memory devices that promise the desired hardware revolution in our intensive data-driven era.

The clinical application of curcumin (CUR) is restricted by its low solubility, instability, and poor bioavailability. To overcome these limitations, we developed a novel stearic acid-grafted inulin-based nano-delivery system for CUR encapsulation. The structure of stearoyl inulin (SA-IN) was characterized using Fourier-transform infrared spectroscopy, hydrogen nuclear magnetic resonance, thermogravimetric analysis, and contact angle measurements.

Proteases are overexpressed at various stages of conditions such as cancers and thus can serve as biomarkers for disease diagnosis. Electrochemical techniques to detect the activity of extracellular proteases have gained attraction due to their multiplexing capability. Here we employ an electrochemical approach based on a 3 × 3 gold (Au) microelectrode array (MEA) functionalized with (2-aminoethyl)ferrocene (AEF) tagged specific peptide substrates to monitor cathepsin B (CB) protease activity.

Aptamers and aptamer-drug conjugates (ApDCs) have shown some success as targeted therapies in cancer theranostics. However, their stability in complex media and their capacity to evade lysosomal breakdown still need improvement. To address these challenges, we herein developed a one-step self-assembly strategy to improve the stability of aptamers or ApDCs, while simultaneously enhancing their delivery performance and therapeutic efficiency through a lysosome-independent pathway.

Nanoparticle-based drug delivery systems hold great promise for improving the effectiveness of anti-tumor therapies. However, their clinical translation remains hindered by several significant challenges, including intricate preparation processes, limited drug loading capacity, and concerns regarding potential toxicity. In this context, pure drug-assembled nanosystems (PDANSs) have emerged as a promising alternative, attracting extensive research interest due to their simple preparation methods, high drug loading efficiency, and suitability for large-scale industrial production.
