New Sun Screen Lotion made of Engineered Zinc Oxide Nanoparticles (E-ZnO NPs) by IIT Bombay

• Sunscreens have core ingredient called zinc oxide nanoparticles (NPs) which block a portion of Ultra violet Rays -  UVA – but they also emit some UVA of their own which then penetrates the dermal layer of the skin and enhances the generation of ‘cancer-inducing radicals’. 
• IIT Bombay has made what they call engineered zinc oxide nanoparticles (E-ZnO NPs) 
• New E-ZnO NPs can bypass harmful UVA and UVB emission while at the same time make it a “broadband UV absorber and broadband visible emitter”
• This visible emission is neither harmful nor dangerous for the skin when compared to UVA emission from normal zinc oxide NPs
• The scientists also said E-ZnO NPs can impart a “brightening effect” or glow to the human skin. 
• With its camouflaging effect, it will find its utility in wrinkle-free creams
• Harmful Impacts of UVA
• Damages DNA and other biomolecules due to its ability to generate ‘reactive oxygen species’ which damages human genetic material, thereby leading to cancer. 
• A recent WHO report said one of every three cancer cases was of the skin and UV rays were a major culprit.
