**11. Silver nanoparticles for catheter modification**

In generalmicrobes adhere on the surface of the catheters and growsrapidly forming biofilmsin such environmental conditions leading to bloodstream infections, even worse. Silver impregnated catheters have already been used in clinical fields and silver nanoparticles are applied in number of biomedical devices. Methods like solvent casting, electrospinning, electrospraying, and silver iontophoretic technology were being used for the synthesis of silver impregnated catheters. The nature of silver nanoparticles and the coating incorporation will determine the efficacy and durability of the medical devices.
