Antimicrobial Properties of Semiconductor Nanoparticles

Several metals have been reported to possess antimicrobial properties. Out of these metal nanoparticles, some semiconductor nanoparticles are expectant solutions to the pathogenic activities of microorganisms. Many studies have proved that these nano-sized particles are effective against several Gram-positive as well as Gram-negative pathogenic bacteria. Different types of nanoparticles are synthesized from different metals, and according to their size, they show effective responses against the target microorganisms. The exact mechanism of the antimicrobial effect has not been confirmed, but some supposed methods have been described. These particles also help to decrease antibiotic pollution as the hefty use of antibiotics can bring drastic changes in the environment and livings beings in the form of side effects. nbsp;
