摘要：

Hypothesis: Polyphosphate nanoparticles as phosphatase-degradable carriers for Penicillium chrysogenum anti -fungal protein (PAF) can enhance the antifungal activity of the protein against Candida albicans biofilm. Experiments: PAF-polyphosphate (PP) nanoparticles (PAF-PP NPs) were obtained through ionic gelation. The resulting NPs were characterized in terms of their particle size, size distribution and zeta potential. Cell viability and hemolysis studies were carried out in vitro on human foreskin fibroblasts (Hs 68 cells) and human eryth-rocytes, respectively. Enzymatic degradation of NPs was investigated by monitoring release of free mono -phosphates in the presence of isolated as well as C. albicans-derived phosphatases. In parallel, shift in zeta potential of PAF-PP NPs as a response to phosphatase stimuli was determined. Diffusion of PAF and PAF-PP NPs through C. albicans biofilm matrix was analysed by fluorescence correlation spectroscopy (FCS). Antifungal synergy was evaluated on C. albicans biofilm by determining the colony forming units (CFU).
