Resumo
Introduction: The increasing prevalence of fungal infections, particularly those caused by Candida albicans, presents a significant clinical challenge due to the emergence of drug-resistant strains. Silver (I) coordination complexes show promise as antifungal agents; however, their poor water solubility limits clinical application. Methods: In this study, we developed and characterized a lipid nanoemulsion (Ag-LN) to enhance the delivery and activity of a silver (I) complex. Results: The formulation exhibited nanoscale size, spherical morphology, and stability for up to 60 days. Ag-LN showed potent antifungal effects, preventing biofilm formation and eradicating mature biofilms. Importantly, nanoencapsulation preserved antifungal activity while reducing mutagenic potential and acute toxicity compared with the free compound. Conclusions: These findings support Ag-LN as a promising antifungal platform for future preclinical studies.
