Silver nanoparticles (AgNPs) were synthesized using two white rot fungi; the extract was acted as a reducing and stabilizing agent. The formation of AgNPs was observed by UV- Vis spectroscopy and surface plasmon resonance (SPR) occurred at 420 nm. The SEM analysis revealed that fixing of synthesised nanosilver in treated fabrics. Furthermore, the biologically synthesized AgNPs were immobilized on cotton fabrics and screened for antibacterial activity. The immobilized AgNPs on cotton cloth showed high antibacterial activity against S. aureus, M. leutes, K. pneumoniae and P. aeruginosa species. Therefore, they could be a viable alternative source in treating wounds or may help in replacing pharmaceutical band-aids.
