“…An unconventional application of polymeric materials was also reported in the bio-medical field, considering the development of a novel adsorbent capable of adsorbing influenza viruses in the form of aerosols in the air [ 5 ]. In particular, a functional group, i.e., N-acetylneuraminic acid, was introduced into a microfiber nonwoven fabric, manufactured through radiation-induced graft polymerization (RIGP), and sialic acid was immobilized to mimic the sugar chain cluster effect.…”
