The ongoing global pandemic due to the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) is in the crucial stage. The vaccine is still at the
developing stage. Currently, the only way to check the spreading of this virus is
self-isolation. It is reported that a good number of health workers are infected
while treating patients suffering from COVID 19. Therefore, an effort is made to
develop a system that can enhance safety and check unwanted viruses. Although the
complete specification of the SARS-CoV-2 is yet to be evaluated, the present work
considers the characteristic of SARS-CoV-1, which closely relates to that of
SARS-CoV-2. The proteins are one of the most important structural and functional
molecules of the virus; therefore, few properties of a protein are considered. In
this work, we propose a sanitization procedure of the personal protective
equipment (PPE), such as gloves and masks, before and after the use, by employing
high voltage charge generator (30 kV) from a very low DC source of 5 V to
eliminate the virus from the surface of PPE. The positive output is connected to
a metallic surface coated with carbon nanotubes (CNT) or a metallic surface
ablated using lithography to achieve desired nano-grooves of 200 nm. At the tip
of these nano-grooves, a very high electric field is generated which readily
ionises the air in the vicinity of the tip. The high electric field alters the
induced dipole of the protein of the virus, causing permanent damage in terms of
electroporation. Further positive salt ions diffuse into the protein of the
viruses, causing it inactive and disintegrate.
