Gold nanoparticle conjugation enhances berberine's antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA).

Nanoparticle (NP) conjugation with various biomolecules is one of the most promising approaches for targeting Methicillin-resistant Staphylococcus aureus (MRSA). In this study, berberine (BER) was conjugated with gold nanoparticles (AuNPs) to enhance its antibacterial activity against MRSA. Chemically synthesized AuNPs were characterized by UV-vis spectroscopy, size distribution and Field Emission-Scanning Electron Microscope (FE-SEM) analysis.
