DST FUNDED STARTUP DEVELOPS CHEMICAL FREE SILVER BASED DISINFECTANT TO FIGHT COVID 19

Why in news?
 

A Department of Science and Technology funded startup has developed chemical free silver based disinfectant to fight the COVID 19 pandemic. 

Details:

  • Weinnovate Biosolutions, a Pune based startup supported jointly by the Department of Science and Technology (DST) and Department of Biotechnology (DBT), has come up with a non-alcoholic aqueous-based Colloidal Silver solution for disinfecting hands and environmental surfaces.
  • This liquid is noninflammable and free of hazardous chemicals and can be an effective sanitizer to prevent the spread of the COVID-19 infection.
  • It has been developed through the NanoAgCide technology 
  • This sanitizer is based on the ability of the silver nanoparticles to prevent the synthesis of viral negative-strand RNA and viral budding.
  • An Indian patent has been filed for the process of making colloidal silver, and a test license for making hand sanitizers and disinfectants has been granted. 

Nanoparticles:

  • Nanoparticles are rapidly emerging as effective solutions to a variety of issues related to COVID-19, from theranostics (therapy plus diagnostics) to disinfection and imaging. 
  • The relevance of nanoparticles is owing to their size (less than 100 nm), which is comparable to that of COVID-19 virus, and a plethora of functionalities such as targeting and drug delivery that can be tailored to match the needs.
