A Review on Antimicrobial Effect of Silver Nanoparticle against Biofilm Producing Bacteria

In recent era multi drug resistant biofilm forming bacteria band Nanotechnology is a burning field for the researchers. Microbial infection caused by Biofilm forming bacteria due to ability of these bacteria to form Biofilm. Formation of biofilm is characteristic for various gram negative and gram positive bacteria hence Staphylococus aureus are most common biofilm producing bacteria. Biofilm composed by several layers of bacterial encased with in an exopolysachharide matrix. In this review it has been observed that Nanotechnology play a key role in control and prevention of the infection occur due to multidrug resistant biofilm forming bacteria. In most of the observation antimicrobial effect of silver nanoparticle it has been determine by disc diffusion and microdilution technique. For the determination of biofilm production Congo Red agar technique and Tube technique has been used. Due to the significance of biofilm in medical science and increase of drug resistance, silver nanoparticle can play a vital role for the prevention and control of biofilm
