Antiviral surface for Covid-19 – the new research which can control the spread of virus. This can be a new hope for India’s COVID crisis. The more the virus spreads, the more likely it is to mutate and develop variants, which will potentially resist existing vaccinations that aim to disrupt the pandemic success of other nations. The researchers came up with a new study that can help control the virus spread through surfaces designed with antiviral properties.
India’s difficulty in controlling COVID-19 spread
The health sector of India is on the verge of failure. Oxygen equipment, ventilators and beds storage in hospitals across the country. People are looking out for remedies, causing prices to rise, while laboratories are struggling to process the growing COVID 19 test.
It will devastate the humanitarian situation for approximately 1.4 billion people of the country. The poor heath care system, shortage of medication, beds, ICU, ventilators, oxygen and many more are causing deaths and the spread of virus. The vaccine shortage is also one of the major issues and that can lead to more cases in future.
Antiviral Surface for Covid-19
A potential source of disease transmission is a respiratory droplet from a person tested positive with the coronavirus on the surface. The process of disease propagation, which acts as a medium to the virus survival, is known as the fomite phase of the respiratory droplet. Antiviral Surface for Covid-19 to get under control is a need of the hour in India.
The duration of the droplet is determined by the probability of spreading a virus on the surface land. Whereas 99.9 per cent of the liquid content of the droplet evaporates in a couple of minutes, the virus will thrive from a small residual film.
The possibility of designing surfaces to limit virus survival, like the COVID-19.
In the field of Fluid Physics, IIT Bombay researchers discuss how the rate of evaporation of residual thin films can be increased with the adjustment of the weight of surfaces and geometrical micro-textures.
A surface that is perfectly engineered will dissolve quickly and reduce the risk of viruses spreading.
In physics, the combined surface technology and disjoining pressure in the remaining, thin-film improve the solid-liquid interfacial force, which will accelerate the drying of the thin layer.
The shocking outcome
The scientists were shocked to find that its antiviral effects are determined by combining the weakening and the actual texture of a rock.
If one of these parameters is continually adapted, the optimal outcomes could not be achieved. The most leading antiviral result is a range of wettability and texture that is optimised.
In prior research, the nature of superhydrophobic surfaces (spreads the water), shows that surface hydrophilicity can be accomplished using antiviral design (attracts water).
“Our work today shows that it is possible to design anti-COVID-19 surfaces,” said Janini Murallidharan, co-author of the book. “We also suggest a technique of architecture and specifications for engineering surfaces with the shortest period of virus survival.”
Antiviral effect on surface design
The researchers found the best anti-viral effect or the shortest drying period on surfaces with wider, densely packed pillars with an angle of touch of about 60 degrees.
This research paves the way for the production of antiviral surfaces that are valuable in the construction of the hospital, medical and pathological devices or surfaces often affected, such as door handle systems, mobile displays or surfaces inside outbreak-prone areas.
“Through fomite transmission, our model will easily apply to respiratory conditions such as influenza A,” said Rajneesh Bhardwaj, co-author.
“This model will be expanded. Since the antiviral effects have been analyzed by a general model separate from the particular texture geometry, some geometric structures can be manufactured based on various ion beam or chemical gravure techniques, so that the same results can be achieved.”
