Abstract
BackgroundRising global mortality due to antibiotic-resistant pathogens necessitates novel antibacterial and antifungal agents. This study focuses on synthesizing gold nanoparticles (GNPs) via tricyclic microwave irradiation (TMI) to combat Multi-Drug-Resistant Bacteria and Fungus. The demand for sustainable synthesis methods has led to the exploration of TMI for GNP production.ResultsCharacterization demonstrates consistent, uniform, and dispersed GNPs with trigonal and hexagonal shapes. GNPs sized 20–55 nm exhibit superior antibacterial and antifungal activity, particularly against drug-resistant Gram-positive bacteria. Notably, GNPs display consistent efficacy against drug-resistant fungus and demonstrate potential for broad-spectrum antimicrobial applications.ConclusionTMI-synthesized GNPs, characterized by their favorable physical properties and size-dependent efficacy, show promise as effective agents against drug-resistant pathogens. Their ability to combat Gram-positive bacteria, Gram-negative bacteria, and drug-resistant fungus positions them as valuable tools in biomedical sciences. By addressing the urgent need for novel antimicrobial agents, TMI-synthesized GNPs offer a sustainable solution to the escalating global health challenge of antibiotic resistance.
