Nanocapsules with glycerol monolaurate: Effects on Candida albicans biofilms

Candida albicans does not only occur in the free living planktonic form but also grows in surface-attached biofilm communities. Moreover, these biofilms appear to be the most common lifestyle and are involved in the majority of human Candida infections. Nanoparticles can be used as an alternative to conventional antimicrobial agents and can also act as carriers for antibiotics and other drugs. In view of this, the aim of the study was develop, characterize and verify the anti-biofilm potential of GML Nanocapsules against C. albicans. The GML Nanocapsules showed mean diameter of 193.2 nm, polydispersion index of 0.044, zeta potential of −23.3 mV and pH 6.32. The microdilution assay showed MIC of 15.5 μg mL−1 to GML Nanocapsules and 31.25 μg mL−1 to GML. The anti-biofilm assay showed the significantly reduction of biomass of C. albicans biofilm treated with GML Nanocapsules while the GML does not exhibit effect. The kinetic assay demonstrated that at 48 h, the GML Nanocapsules reduce 94% of formed biofilm. The positive results suggest the promisor alternative for this public health problem that is biofilm infections. •The nanocapsules showed acceptable values of characterization.•The GML Nanocapsules have activity against formed biofilm.•There was inhibition of biofilm formation by GML Nanocapsules.•On 48 h the GML Nanocapsules virtually exterminated the biofilm.
