Non-allergic and anti-microbial N95 mask with nanoparticle coating through 3D printing technology

by Aug 20, 2022Health0 comments

In collaboration with the University of Nebraska, USA , researchers from Amity University (Haryana) 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.

The product, developed through the two universities, one Indian and the other American, can be called a true Indo-US venture that has immense potential as a prophylactic.

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 factories, 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, to be called NanoBreath.

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, the third layer is a 100 µm filter and the fourth layer is a moisture absorbent filter.

It is a high performance, versatile system for measuring particle size, zeta potential, molecular weight, particle mobility and micro-rheology.

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.

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.
