Water Disinfection using Immobilized Silver Nanoparticles Dead bacterium Sharda Bharti 1, Prof. Soumyo Mukherji 2 & Prof. Suparna Mukherji 1 1 Centre for Environmental Science & Engineering 2 Department of Bioscience & Bioengineering IIT Bombay, Mumbai, India Sharda Bharti 1, Prof. Soumyo Mukherji 2 & Prof. Suparna Mukherji 1 1 Centre for Environmental Science & Engineering 2 Department of Bioscience & Bioengineering IIT Bombay, Mumbai, India Summer Institute on Nanotechnology IC-IMPACTS 2016

Project Objectives Schematics of experimental set-up Fabrication of a robust nanodevice using immobilized silver nanoparticles Point-of-use water disinfection Unique, easy to operate and cost-effective

Performance Evaluation of the Reactor Larger number of BV processed and lower AER value in case of 100ml/min revealed the better performance. Results

Analysis of silver leaching and mechanism of Action AgNPs Cell wall and membrane disruption Denaturation of protein and DNA ROS generation Inhibition of signal transduction Predominant Mode: contact mode killing Multiple mechanism of action of AgNPs proved them as a potential nanoantimicrobial.
