NOVEL BIOSYNTHESIS OF METAL NANOPARTICLES BY HEAVY METAL-RESISTANT BACTERIA

摘要

Nanomaterials have been shown to exhibit unique physical and chemical properties that are highly size and shape-dependant. The ability to control synthesis of nanoparticles with particular shapes and sizes can lead to exciting new applications or enhancements of current systems in the fields of optics, electronics, catalytics, biomedicine and biotechnology. Due to increased chemical pollution and health concerns, biological synthesis of nanomaterials has quickly emerged as being an eco-friendly, scalable, and clean alternative to chemical and physical synthesis. In this study, the inference that the heavy metal-resistant bacteria, Paenibacillus castaneae, has the propensity to synthesize metal nanoparticles (NPs) was validated.
