The synthesis of non-soluble polyampholytes was modified to obtain water-soluble oligomers, by a sequential reaction at 60 °C of imidazole (IM), ethyleneglycol diglycidyl ether (EGDE) and methacrylic acid (MAA). The hydrogel Poly(EGDE-IM) with …
In this work, we present two novel nanostructured hybrid materials based on a chitin matrix loaded with increasing amounts of graphene oxide and reduced graphene oxide nanosheets (nGO and rGO, respectively). Both kinds of material (Chi:nGO and …
Antimicrobial finishings protect users from pathogenic and odor-generating microorganisms, which are of medical and hygiene concerns. Controlled release is a useful approach to obtain antimicrobial finishings in several materials because it provides …
This work presents the synthesis of chitin (Chi) and chitin/graphene oxide (Chi:nGO) hybrid gels in mild conditions and their use as biosorbents in solid-liquid batch systems. The graphene oxide nanosheets, obtained from natural graphite through …
Previous studies by our group demonstrated the key role of iron in Schwann cell maturation through an increase in cAMP, PKA activation and CREB phosphorylation. These studies opened the door to further research on non-transferrin-bound iron uptake, …
A coating comprising quaternary ammonium salts (QAS) and aliphatic moieties was formed on the poly(vinyl chloride) (PVC) surface in order to confer antibacterial activity. This was achieved by grafting mercaptopropyltrimethoxysilane onto PVC, …
Linear poly(ethylenimine hydrochloride) (PEI·HCl) polymers with different molecular weights (22, 87, and 217 kDa) and their copper complexes (Cu-PEI) were studied with particular attention to the crystalline/amorphous character of the polymeric …
Chitin hybrid materials reinforced with graphene oxide nanosheets (nGO) have been prepared. The chitin : nGO ratio ranged from proportions where chitin was the main component to ones where nGO exceeded chitin. SEM and TEM images showed that high …
The hospital environment is particularly susceptible to contamination by bacterial pathogens that grow on surfaces as biofilms. An increased risk of disease may be a direct consequence of their formation. Understanding bacterial adhesion to surfaces …
