摘要

The synthesis of metal nanoparticles (NPs) loaded on the ultrasonic-assisted (MNPs/UASP) was investigated using the green synthesis method. The algal extract was taken as a reducing agent. The formations of metal NPs were characterised using UV-visible spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy. The antimicrobial activity of different metal NPs demonstrated various inhibitory activities against one gram-positive bacteria (), four gram-negative bacteria (, , and ) and one fungus (). Both CrNPs/UASP and ZnNPs/UASP show good antimicrobial activity when compared with other MNPs/UASP against microorganisms. This MNPs/UASP is effective in preventing and treating the microbial infection and water pollution in the environment.
