IIT Hyderabad researchers develop their own hand sanitizer
IIT Hyderabad (Indian Institute of Technology Hyderabad) researchers have developed their own hand sanitizer. Sources say, the hand sanitizer would be put to use inside the premises of the educational institution.
Sanitizer was prepared in tandem with the World Health Organisation (WHO) standards and has 70% alcohol which can penetrate the cell wall, coagulate all proteins leading to the death of micro organism.
The sanitizer was developed by Dr. Shivakalyani Adepu who was a research scholar at the Department of Materials Science and Metallurgical Engineering, IIT Hyderabad along with Dr. Mudrika Khandelwal, Associate Professor, Department of Materials Science and Metallurgical Engineering, IIT Hyderabad.
Around ten liters of this hand sanitizer have already been deployed in the campus for the benefit of the students, staff and faculty at locations such as faculty lounge, Shiru Café, meeting halls and laboratories and other areas.

Placing the sanitizer at various locations inside the IIT Hyderabad will allow more people to use it which will help stop the spread of germs and promote good health and hygiene.
Mudrika Khandelwal said their research group has always believed in doing scientific research and outreach for the benefit of society. This is their small contribution at the time of need. ‘I am glad we would make this happen and hope to make similar contributions in the future.’
The 70 per cent IPA solution penetrates the cell wall, coagulates all proteins and therefore the micro organism dies,’ said Mudrika. Dr. Shivakalyani who completed her PhD last month said this was done purely to support the community at this time when it is critical to adopt safe and hygienic practices.
‘We have not thought of commercialization. Our motto is to help people around us. We can assure that these are as safe as any commercial sanitizer and possibly more effective.’
Our laboratory conducts a lot of microbiological studies and we have tested these kinds of materials before and have been using the same for several years now. Its efficacy is well known and has been reported, she said.
According to WHO and CDC, hands account for transmitting nearly 80 per cent of the infections due to frequent touching of eyes, nose, mouth and ears which leads to the entry of germs.
Nearly one in five people do not regularly wash their hands. Of those who do, 70 per cent do not use soap. The alcohol-based hand sanitizers kill most bacteria and fungi and stop some viruses present on hands within 30 seconds of application.
If 70 percent of alcohol is poured to a single-celled organism, the diluted alcohol also coagulates the protein, but at a slower rate, so that it penetrates all the way through the cell before coagulation can block it. Then the entire cell is coagulated and the organism dies.
