Antibacterial Graphene masks can prevent Corona virus too ?

          Until now face masks have been one of the effective means to decrease the spread of respiratory virus diseases . But the same mask, if improperly used or inappropriately discarded, can negate the insignificant protection offered by the mask. Studies have shown that outside area of the used masks are highly contaminated and it is directly proportional to air quality of the working environment. Majority of bacteria on the mask remain alive even after 8 hours of use. To tackle this problem, a group of researchers from City University of Hong Kong, China demonstrated that by using Laser-Induced Graphene (LIG) in masks, the antibacterial property can be significantly improved. And if combined with photothermal effect (sun light) , the bactericidal property can be increased up to 99.99% within 10 minutes. According to the preliminary report of the study published in ACS Nano, the team of researchers demonstrated the antibacterial activity of LIG using Escherichia coli ( E. coli

Russia’s SPUTNIK V finds an Indian partner- Dr Reddy’s Laboratory

  Russian Direct Investment Fund  (RDIF), a sovereign wealth fund in Russia has allied Dr Reddy’s Laboratories (DRL), the Hyderabad-based drug manufacturer to cooperate on clinical trials and distribution of Sputnik V vaccine in India. This arrangement claims to deliver the vaccine for general use probably beginning late 2020. After obtaining regulatory approvals from DCGI (Drug Controller General of India) for conducting trials in India, DRL will receive 100 million doses of the Covid19 vaccine — developed by the Gemaleya National Center of Epidemiology and Microbiology (Moscow, Russia). The results of the early phases (Phase 1 and 2) of trials with the vaccine were recently published in Lancet in September 2020, while both India and Russia were laying the groundwork to pursue further trials and production of the vaccine in India. The Indian Council of Medical Research (ICMR) expresses that Russia has a good track record in development of vaccines. Sputnik V is based on proven va
