Palladium NPs (PdNPs) are easy to synthesize, stable, have low cytotoxicity and good biocompatibility, and can be modified for use in biomedicine. PdNPs were synthesized chemically and modified with the biopolymer chitosan and the targeting ligand transferrin (Tf). This was used to encapsulate the anticancer drugs doxorubicin (DOX) and 5-fluorouracil (5-FU) individually and as a dual-drug formulation. PdNPs were spherical, small (98.9 nm), and had good colloidal stability (zeta potential = −22.3 mV). High drug encapsulation efficiency (>70 %) was noted for both drugs, with a sustained release profile for the Tf-modified PdNPs at low pH for both drug formulations over 72 h. These PdNPs were targeted to a cervical cancer cell model (HeLa) that highly expresses the Tf receptor. Cytotoxicity was assessed on the human embryonic kidney (HEK293), breast adenocarcinoma (MCF-7), and HeLa cell lines. The anticancer activity confirmed the targeting specificity of the Tf-containing nanocomplexes to the HeLa cells, with good cell viability in the non-cancer (HEK293) cells.

The current research focused on the preparation of boric acid (BA) crosslinked PVA composite membranes with cellulose nanofiber (CNF). Herein, BA acts as an antibacterial agent against bacterial infection and together with CNF provides mechanical integrity to the composite membrane. Furthermore, these membranes were subjected to surface functionalization with plasma polymerization, a technique that controlled not only their swelling behaviour but also improved their antibacterial properties. The composite membranes were then subjected to an antibacterial performance test against <em>Staphylococcus aureus</em> and <em>Pseudomonas aeruginosa</em>, which showed remarkable bactericidal activity. The cytocompatibility was done by cell viability assays and fluorescent staining, confirming the nontoxic nature and biocompatibility of the membranes with macrophages. Besides, contact angle measurements showed favourable hydrophilicity (44 ± 1.4 °) to promote cell adhesion, and tensile testing showed optimal mechanical properties at 2.5 phr cellulose nanofiber and 8 phr BA content. The antibacterial activity, mechanical robustness, and cytocompatibility shown by plasma coated PVA-BA-CNF membrane, make them ideal candidates for biomedical applications.

This approach explores potential uses for these materials in various fields. These studies suggest that as-deposited thin films are composed of rod-shaped particles, and the shape was found to change from thick to fine with the increase in Ag content. The amount of dopant has a significant impact on its properties and crystallinity. We observed an increasing number of particles transitioning into smaller sizes with the rise in Ag content. Optical absorptions (300–900 nm) at room temperature suggest a direct bandgap that increases with an increase in doping content. This is an indication of the presence of defect states and the high density of localized states. The width of the Urbach tails in the localized states shows a narrowing trend with an increase in doping content. This could potentially be attributed to a decrease in the band tails, leading to an increase in the optical band gap. Moreover, as-synthesized material indicated superb chemical stability.
