Union Minister Dr Jitendra Singh says, India has developed copper based nanoparticle coatings on fabric which can be used as self-disinfection masks which give 99.9% protection from the infection
Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said that India has developed copper based nanoparticle coatings on fabric which can be used as self-disinfection masks which give 99.9% protection from the infection.
In a written reply to a question in the Lok Sabha today, Dr Jitendra Singh said, the unique mask has been developed by International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI), Hyderabad and Centre for Cellular & Molecular Biology (CCMB), Hyderabad and Resil Chemicals Pvt Ltd, Bangalore.
The Minister informed that Copper-based nanoparticles have been prepared by a Flame Spray Pyrolysis (FSP) processing facility established at ARCI and stable nanoparticle suspension is prepared by optimizing the solid loading and pH. A uniform layer of this nano-coating on the cotton fabric with good adhesion was achieved using a suitable binder. The efficacy of the coated fabric against SARS CoV2 was evaluated by CCMB and also tested for other virus and bacteria.
Few thousands of masks have been produced by the industry partner, Resil Chemicals Ltd for pilot scale demonstration and they are being tested for certification. The mask cannot be compared with other masks as the technology of other masks available in the market is not well known.
