27-Jun-2022: N95 mask with nanoparticle coating developed using 3D printing technology
Researchers have developed a reusable, recyclable, washable, odourless, non-allergic and anti-microbial N95 mask by using 3D printing technology. The four-layer mask whose outer layer is made up of silicon has a shelf life of more than 5 years depending upon the use.
Apart from its well-known uses to prevent infections like COVID 19, the mask can also be used by workers in different industries where they are exposed to high volumes of dust like cement factory, brick kilns, cotton factories and pain industries. It can be modified according to the requirement by changing the filter configuration according to the place in which it will be used and can help prevent severe lung diseases such as SILICOSIS. A trademark and a patent have also been filed for the mask called Nano Breath.
A 4-layer filtration mechanism has been provided in the mask wherein the outer and first layer of the filter is coated with nanoparticles. The second layer is a high-efficiency particulate absorbing (HEPA) filter, third layer is 100 µm filter and fourth layer is moisture absorbent filter.
Dr. Atul Thakur, Dr. Preeti Thakur, Dr. Lucky Krishnia, and Prof. P. B. Sharma, Dinesh Kumar research scholar from Amity University Haryana (AUH) and Prof. Rakesh Srivastava from University of Nebraska, USA have jointly developed this product that has immense potential as a prophylactic.
A Zetasizer Nano ZS, a facility supported by ‘Fund for Improvement of Science & Technology Infrastructure’ (FIST) project of the Department of Science & Technology (DST), Government of India which enables high temperature thermal analysis for ceramic materials and catalysis applications, has been used to carry out this work. It is a high performance, versatile system for measuring particle size, zeta potential, molecular weight, particle mobility and micro-rheology.
4-Feb-2022: Scientists develop self-disinfecting, biodegradable face masks to combat COVID-19
A team of Indian Scientists in collaboration with an industry partner have developed a self-disinfecting ‘Copper-based Nanoparticle-coated Antiviral Face Mask to fight against the COVID-19 pandemic. The mask exhibits high performance against the COVID 19 virus as well as several other viral and bacterial infections, is biodegradable, highly breathable and washable.
Public mask wearing is most effective in reducing the spread of the virus COVID-19 caused by SARS-CoV-2, an enveloped positive sense single-stranded RNA virus, where the mode of transmission is via respiratory particles that are mainly airborne.
With the science around the use of masks to impede transmission is advancing rapidly, the Indian market is selling expensive masks that neither exhibit antiviral nor antibacterial properties. Hence, it is very difficult to control the transmission by wearing the conventional mask particularly in densely populated places like hospitals, airports, stations, shopping malls and so on where the virus load is very high. In the present scenario, where mutations in coronavirus causing the COVID-19 pandemic are fast emerging, it is an urgent necessity to develop a low-cost antiviral mask.
To this end, Scientists at International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous R&D Centre of Department of Science and Technology (DST), Govt. of India, in collaboration with the Centre for Cellular & Molecular Biology (CSIR-CCMB) and Resil Chemicals, a Bengaluru based company have developed the self-disinfecting ‘Copper-based Nanoparticle-coated Antiviral Face Masks’ under the DST sponsored Nano-Mission project, to fight against the COVID-19 pandemic.
ARCI developed copper-based nanoparticles of around 20 nanometres by a Flame Spray Pyrolysis (FSP) processing facility. FSP process involves conversion of solution precursors into nanopowders by high temperature pyrolytic decomposition. Stable nanoparticle suspension were obtained 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 coated fabric exhibited an efficacy of more than 99.9% against bacteria. CSIR-CCMB tested the efficacy of this fabric against SARS-CoV-2 for their disinfection properties and reported 99.9% disinfection, as evident from the standard results. Prototype masks having different designs such as single layer and triple layers with nanoparticle coated fabric as outer layer have been demonstrated. A single layer mask is especially useful as a protective antiviral outer mask over a regular mask.
Their Industrial partner Resil Chemicals Bengaluru is now producing such double layer masks on large scale. The present-day face masks only retain the viruses by filtering and do not kill them and hence, are prone to transmission if the masks are not properly worn or disposed. Simple multi-layer cloth masks present a pragmatic solution for use by the public in reducing COVID-19 transmission in the community and wearing these self-disinfecting cloth masks is definitely one of them.
Additionally, a huge concern is expressed around the globe regarding the disposal of used masks. Most of the conventional masks effective against COVID-19 are for single-use and are not bio-degradable, creating serious environmental concerns and waste-management issues. The present antiviral mask which is made from cotton fabric that is biodegradable would eliminate that problem too besides making it highly breathable and washable.
31-Dec-2021: Union Minister Dr Jitendra Singh says, Tele-medicine technology is going to be the main pillar of India’s future health care system
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 today said that Tele-medicine technology is going to be the main pillar of India’s future health care system.
Launching the Tele-Digital Healthcare Pilot Program at BHU, Varanasi, Dr Jitendra Singh said, innovative healthcare solutions like Tele-medicine could save India between 4-5 billion US dollars every year and replace half of in-person outpatient consultations. The Minister said that Prime Minister Narendra Modi’s Digital Health Mission is the next frontier to ensure healthcare delivery is accessible, available, and affordable to all, particularly the poor living in rural and inaccessible terrain. He said, Telemedicine in the country has proven to be cost effective by about 30% less than equivalent in-person visits.
Dr Jitendra Singh said that though Telemedicine technology was in vogue for quite some time in the country, but it got a fillip in post-COVID era and in the wake of PM Modi’s push to Digital Health Ecosystem in India.
Referring to Drone delivery of vaccines in some parts of India, the Minister said, with rapid advancement in technology, Robotic Surgery will also become a reality very soon and future doctors will increasing don the mettle of Tele-Doctors.
Pointing out to very low doctor-patient ratio in India that is about one per 1,457 Indian citizens, Dr Jitendra Singh said, Tele-medicine is no longer an option but a necessity. He said, about 65 percent of India’s population that lives in rural villages, where the doctor-patient ratio is as low as one doctor per 25,000 citizens and therefore they must get best of medical advice from doctors based in towns and metropolitan cities. He said, Telemedicine will not only help the patients save their time and money, but also the doctors who can quickly assist their patients over a call for the same and actively engage in promptly treating patients with major ailments.
Dr Jitendra Singh said, the project starting in three districts of Varanasi, Gorakhpur and Kamjong in Manipur will cover 60,000 patients in the initial phase and it will be scaled up gradually to cover the entire country in the coming years. Technology Information, Forecasting and Assessment Council (TIFAC), an autonomous body of Department of Science and Technology at the Centre has designed a pilot Tele-diagnostics project in collaboration with IIT Madras-Pravartak Foundation Technologies & CDAC Mohali. This will also generate Electronic Health Record (EHR) for Indian population.
The Minister said, the project is a scalable pilot PLUG and PLAY model oriented to provide quality medical care to underprivileged women and children living in remote areas at affordable costs. The key activities include examination of the patients: women/ children with wearable devices, transferring the health data record through the e-Sanjeevani cloud to a pool of doctors for analysis, and concurrently for development of EHR. The parameters that would be analysed include: ECG, Heart Rate, Blood Pressure, Lipid Profile, Haemoglobin & Foetal Doppler.
It may be recalled that Dr Jitendra Singh has established tele-consultation facility in his Lok Sabha Constituency of Udhampur-Kathua-Doda from his MP-LAD Fund, in the District Hospital Udhampur with all the Panchayats connected with it and it is being monitored on a regular basis.
Dr Jitendra Singh said that Prime Minister Narendra Modi has given very high priority to the Health Sector and this year’s budget increased the spending on healthcare by 137%, which is in line with industry expectations of 2.5%-3% of the GDP. The Minister informed that India will spend Rs 2.23 lakh crore on healthcare this fiscal including Rs 35,000 crore on Covid-19 vaccines.
The Minister said that various health care schemes launched by Modi Government such as PM Ayushman Bharat Health Infrastructure Mission, Ayushman Bharat Jan Arogya Yojana, Ayushman Health and Wellness Centres, Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) and Ayushman Bharat Digital Mission have made healthcare facilities accessible and affordable to millions of poor people in the country.
