Dear Editor,

As we know, SARS-CoV-2 spreads when you cough, sneeze, talk, sing, laugh, or breathe out rapidly.[1] Therefore, to protect the individuals or health-care workers, the WHO and CDC have given their standard precautions to use the different types of masks depending on the load of SARS-CoV-2 in their working area.[2],[3] Furthermore, not only we should protect ourselves from SARS-CoV-2 through respiration, but also we should take a precautions not to transfer the attached virus through our clothing, e.g., surgical or homemade masks and medical clothing. For these reasons, we made a modified molecule of macrocycle (Ghanavi, United States patent; 10147951) and coated into clothing surface using spray. After its exposure to contaminated area, the attachment of virus was observed under scanning electron microscopy (SEM). As shown in [Figure 1] and [Figure 2], after using the spray with modified macrocycle, the load of SARS-CoV-2 (COVID-19) attachment increased to “64 folds” (94%) in the clothing surface and remained attached without blowing to free air. The technology can be used in any clothing materials. This means that we can stop the spread and transmission of virus from contaminated to clean area.
