Antimicrobial activity of Leucas aspera engineered silver nanoparticles against Aeromonas hydrophila in infected Catla catla.

This research describes green synthesis of silver nanoparticles (AgNPs) utilizing Leucas aspera. The synthesized nanoparticles were characterized by UV-visible spectroscopy (UV-vis), dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infra-red spectroscopy (FTIR) and inductively coupled plasmon optical emission spectroscopy (ICP-OES). UV-vis analysis proved the wavelength of the sample to be 429 nm, resembling the surface resonance peak (SPR) specific for AgNPs.
