“…The morphology, size and charges of biosynthesized nanocomposites have influential roles in their bioactivities (e. g. antimicrobial actions), as the diminish size of biopolymers NCs can facilitate their attachment and interaction with microbes’ cells, along with the encapsulated antimicrobials in these NCs [24–26] . Furthermore, the synergistic antimicrobial bioactivities of biopolymers‐based NCs were reported, were they could provide much biosafety to the encapsulated nanometals within such NCs matrix, [26–28] which have great importance for their antimicrobial potentialities and safety toward mammalian tissues.…”

“…The biopolymers‐based nanocomposites (NCs) could be defined as the conjugation of different nanomaterials that include biopolymers to generate novel complexes with diverse structures and activities and have particles sizes in “nano” scale [24,25] . The biopolymers NCs were advised to provide pioneering bioactivities (e. g. antioxidant, anticancerous, antimicrobial ….…”

Skin health and protection are paramount in the pursuit of well‐being and beauty. In this study, we introduce an innovative approach to develop skin protectant agents by nanocomposites derived from natural sources, involves the synthesis of selenium nanoparticles (SeNPs) using squash plant mucilage (SqM), and their integration with nano chitosan (NCht) to create a stable, antimicrobial and efficacious composite. The interactions between nanomaterials were proved via infra‐red analysis and electron microscopy. The SqM‐biosynthesized SeNPs had 11.47 nm diameter. Different blends were nanocomposited from NCht and SqM/SeNPs; the NC‐2 nanocomposite (with equal ratios from them) had mean diameter of 241.38 nm and negatively charged. The antimicrobial actions of produced nanomaterials/nanocomposites were validated against skin pathogens, Staphylococcus aureus and Candida albicans, using antimicrobial assays and electron microscopy. The most effectual antimicrobial was NC‐2; the loading of it onto cotton textile provided potent antimicrobial fabrics toward both skin pathogens. The innovative biosynthesis of SeNPs using SqM and their nanocompositing with NCht provided pioneering powerful antimicrobial complexes to control skin pathogens, either through direct interaction or by fabricating hygienic antimicrobial textiles.

“…Two supplementary synthesis routes have evolved from this main reaction manifold. The first alternative, devised by De Jaeger and coworkers in France, , is to obtain poly(dichlorphosphazene) by heating Cl 3 PN–POCl 2 with the concurrent loss of POCl 3 . The second alternative (developed through a collaboration between the Manners group, then in Toronto, and our program at Penn State) starts from a chlorophosphoranimine monomer (top right in Scheme ).…”

Although the best-known examples of synthetic polymers are derived from carbon-based monomers, there exists another large and growing family of macromolecules based on the chemistry of phosphorus. These are the poly(organophosphazenes): polymers with a backbone of alternating phosphorus and nitrogen atoms and with two organic side groups attached to each phosphorus. The methods of synthesis of these polymers allow access to property combinations not found in all-organic counterparts, and this provides pathways to new materials that are important in biomedical research, energy generation and storage, aerospace materials, and numerous other specialized applications.
