Biofilm growth on catheter surface is a challenge for various biomedical applications. Microbial colonization on catheter’s surface leads to many infections. Silicone polymer is a routine material for catheter fabrication. In the present work, silver nanoparticles (NPs) and photosensitive non-toxic dye toluidiune blue (TB) embedded silicon polymer is synthesised by swell encapsulation method and characterised by UV spectroscopy. The embedded polymer showed high bactericidal activity against gram-positive bacteria Staphylococcus aureus (S. aureus) and gram-negative Proteus mirabilis (P. mirabilis) with least leaching effects which suggests their usage as a new weapon to fight catheter related infections.
