9. 2. Photo-responsive functionality
• Nanoparticles have light to heat conversation capacity.
• On exposur to light heat is generated.
• Raised temperature gives antimicrobial activity.
(Applied in wound healing and wound dressing)
• Swelling and mechanical properties of nanocomposites can be
changed by altering exposure to the light.
