PEGylation

Graphene oxide coatings prevent Candida albicans biofilm formation with a controlled release of curcumin-loaded nanocomposites

Aim: Fabrication of graphene oxide (GO)-based medical devices coatings that limit adhesion of Candida albicans, a main issue of healthcare-associated infections. Methods: The GO composites noncovalently functionalized with curcumin (CU), a hydrophobic molecule with active antimicrobial action, polyethylene glycol (PEG) that hinders the absorption of biomolecules or a combination of CU and PEG (GO-CU-PEG) were drop-casted on surfaces and antifungal efficacy was assessed. Results: We demonstrate that GO-CU-PEG coatings can reduce fungal adhesion, proliferation and biofilm formation.

"Click" hyaluronan based nanohydrogels as multifunctionalizable carriers for hydrophobic drugs

Highly hydrophilic and biocompatible nanocarriers based on polysaccharide hydrogels (nanohydrogels,
NHs) were shown to be promising systems for drug delivery applications. Following the idea of these
emerging drug carriers, the aim of the present work was to develop self-assembled hydrogel nanoparticles
based on amphiphilic derivatives of hyaluronic acid (HA) and riboflavin (Rfv), synthesized by “click”
Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC) reaction. The obtained amphiphilic product
