Advancements in nanoparticle-based therapies for multidrug-resistant candidiasis infections: a comprehensive review

Candida auris, a rapidly emerging multidrug-resistant fungal pathogen, poses a global health threat, with cases reported in over 47 countries. Conventional detection methods struggle, and the increasing resistance ofC. auristo antifungal agents has limited treatment options. Nanoparticle-based therapies, utilizing materials like silver, carbon, zinc oxide, titanium dioxide, polymer, and gold, show promise in effectively treating cutaneous candidiasis. This review explores recent advancements in nanoparticle-based therapies, emphasizing their potential to revolutionize antifungal therapy, particularly in combatingC. aurisinfections. The discussion delves into mechanisms of action, combinations of nanomaterials, and their application against multidrug-resistant fungal pathogens, offering exciting prospects for improved clinical outcomes and reduced mortality rates. The aim is to inspire further research, ushering in a new era in the fight against multidrug-resistant fungal infections, paving the way for more effective and targeted therapeutic interventions.

Photocatalytic and antibacterial activities of green synthesized Ag doped MgO nanocomposites towards environmental sustainability

The utilization of MgO nanoparticles (NPs) for Photocatalytic and antimicrobial activities has gained lots of attention in recent years. Since silver is an expensive material, it's of interest to check that doping of very small concentration of silver will increase the pollutant degradation efficiency of composites. Here Aloe Vera plant extract was used for synthesis of MgO, Ag NPs and Ag/MgO-nanocomposites (NCs). Green synthesized NPs and NCs were confirmed by using different techniques like UV-Vis, BET, TGA, FTIR, PL, XRD (optical, functional, Thermal, Structural) EDX, TEM, SEM, XPS, EIS and EPR (morphological, elemental, photoelectrical and ROS) studies respectively. Then NPs and NCs were applied for the photocatalytic activity of methylene blue (MB), phenol and antimicrobial studies of E. coli bacteria. Ag/MgO-NCs showed 90.18% dye and 80.67% phenol degradation in 120 min which killed E. Coli pathogenic bacteria in 25 min under solar light irradiations. In disk diffusion methods, it inactivates 24 mm area of bacterial cell growth. Thus, among these green synthesized NPs and NCs, Ag/MgO-NCs exhibited enhanced photocatalytic and antimicrobial activities.
