摘要：BiOBr nanosheets are important photocatalytic nanomaterials.However,their biological effects remain to be explored.In this study,we investigated the antifungal effect of BiOBr nanosheets on Candida albicans.Strikingly,the nanosheets strongly inhibited the growth of C.albicans [IC50=(96±4.7) mg/L],hyphal development and biofilm formation.Compareed to the antifungal effect of the cationic surfactant cetyltrimethylammonium bromide,the inhibitory effect of the nanosheets on fungal pathogen was attributed to cetyltrimethylammonium bromide adsorbed by the nanosheets.Thermal gravity analysis and cetyltrimethylammonium bromide release experiment indicated that only 0.42％ cetyltrimethylammonium bromide on BiOBr nanosheets was released.Taken together,this study uncovers the contribution of surfactant released from the nanosheets to their antifungal activity.
