Summary: A facile methodology using glutaraldehyde as a cross-linking reagent was explored for in situ modification of PVA electrospun nanofibers doped with AgNPs. The different cross-linking degrees achieved through controlling glutaraldehyde amounts effectively controlled the release rates of Ag. Cross-linked PVA doped with AgNPs exhibited good antibacterial efficacy and low cytotoxicity against various cell lines.

Summary: This study presents a facile method to enhance the antibacterial and antiviral performance of plant fibers through fiber design and in situ assembly of silver nanoparticles (AgNPs). Mechanical refining allows for fiber splitting and improved conformability, while polydopamine (PDA) is precipitated onto the fiber surface and acts as a binder for AgNPs. The resulting fibers exhibit excellent antibacterial and antiviral performance due to the high AgNP loadings and strong bond between AgNPs and fibers.

Summary: In this study, multifunctional and durable textile sensors were developed with a metal coating process. The metal coating was confirmed through the deposition of particles on microfibers, filling the micro spaces between the fibers and facilitating electrical conduction. Further analysis showed optimized plating parameters resulting in improved electrical resistivity, EMI shielding, and Ohmic heating properties. The durability of the conductive textiles was also observed against severe washing, showing good retention of the metal coating.
