Amphotericin B Polymer Nanoparticles Show Efficacy against Candida Species Biofilms.

ABSTRACT: Chronic infections of Candida albicans are characterised by the embedding of budding and entwined filamentous fungal cells into biofilms. The biofilms are refractory to many drugs and Candida biofilms are associated with ocular fungal infections. The objective was to test the activity of nanoparticulate amphotericin B (AmB) against Candida biofilms. AmB was encapsulated in the Molecular Envelope Technology (MET, N-palmitoyl-N-monomethyl-N,N-dimethyl-N,N,N-trimethyl-6-O-glycolchitosan) nanoparticles and tested against Candida biofilms in vitro. Confocal laser scanning microscopy (CLSM) imaging of MET nanoparticles' penetration into experimental biofilms was carried out and a MET-AmB eye drop formulation was tested for its stability. MET-AmB formulations demonstrated superior activity toward
