Contact-active antibacterial polyethylene foils via atmospheric air plasma induced polymerisation of quaternary ammonium salts

State of the art in nonthermal plasma processing for biomedical applications: Can it help fight viral pandemics like COVID‐19?

“…[ 91 ] Whereas the nonpolar chains of QAS/PS interact with the nonpolar, inner part of cytoplasmic membranes, the positive charges on the groups interact with the polar outer part of the membranes, disrupting the electrical and osmotic balance and other important functions of the cell to culminate in bacteriolysis. [ 92 ] QASs have been plasma‐grafted on different surfaces, namely polypropylene, [ 93 ] glass fiber membranes, [ 94 ] and polyethylene foils [ 95 ] to impart antibiofouling properties.…”

A multifunctional carbon dot-based nanoplatform for bioimaging and quaternary ammonium salt/photothermal synergistic antibacterial therapy

“…26 Additionally, the long hydrophobic alkyl chain of QAS could interact with the hydrophilic group of bacteria, then the permeability of the bacterial cell membrane was changed and cytolysis was produced, thereby causing bacterial apoptosis. 24,27 Thus, the synergy of QAS and PTT exhibits great potential for enhancing antibacterial therapy. Recently, carbon dots (CDs) as a new type of nanomaterial have attracted tremendous attention in the biomedical field, which exhibit the advantages of well-documented biocompatibility, high stability, abundant raw materials, excellent optical properties, and a simple preparation process.…”

Comparative Study of Natural Terpenoid Precursors in Reactive Plasmas for Thin Film Deposition

“…The development of two-dimensional materials, including single and multi-layer thin films fabricated from polymers and their composites, is critical for the advancement of miniaturized devices spanning energy, optoelectronics, biomedical and space applications [ 1 , 2 , 3 , 4 , 5 ]. For these devices to function efficiently over extended periods of time, the quality of these films and the precision with which they are assembled need to be sufficiently high [ 6 ].…”
