PHOTO-ELECTRO-CHEMISTRY AND NATURE-INSPIRED SYSTEMS

Advanced Materials and Systems for Biomedical Applications

The development of advanced materials and systems has opened new possibilities for biomedical applications, particularly in areas such as bioimaging, enzyme immobilization, and innovative textile technologies. One notable advancement involves carbon dots (CDs) with tunable fluorescence, which have been validated as effective fluorescent probes for bioimaging applications. In enzyme purification, carbon xerogels (CXs) have emerged as a cost-effective one-step solution for the purification of L-asparaginase (ASNase) from Bacillus subtilis fermentation extracts. Significant efforts have been made to develop efficient strategies for immobilizing L-asparaginase onto multi-walled carbon nanotubes and carbon xerogels. By optimizing immobilization conditions and tuning surface chemistry, these methods enhance enzyme stability and reusability, which is crucial for applications in biomedicine and biotechnology.

Innovative materials are also transforming the textile industry, especially with the introduction of photosensitive nanoparticles such as titanium dioxide (TiO₂). These nanoparticles revolutionize cotton textile cleaning by replacing harsh industrial bleaching methods, offering a greener and more sustainable alternative. Graphitic carbon nitride (GCN-T), a metal-free photocatalyst, further enhances textiles by providing eco-friendly self-cleaning and antimicrobial properties when combined with budget-friendly LED setups.

In the realm of electromagnetic interference (EMI) shielding, materials like TiO₂, Fe₂O₃, and PEDOT have shown exceptional promise. These materials are incorporated into advanced clothing designs, achieving over 30 dB shielding effectiveness, which is crucial for protecting against unwanted electromagnetic radiation. Additionally, textiles coated with 70 wt.% Bi₂O₃ dispersed in a polymeric matrix have surpassed traditional heavy lead-based solutions, offering superior flexibility and efficiency in high-frequency radiation protection.
