研究チームはGoldshield 75を評価し、この特許製品がマスクの繊維を劣化させることなく新型コロナウイルスを効果的に殺傷し、毒性もないことを確認しました。また、コーティングされたマスクは、テストサイクルを繰り返しても、また高温で保管しても、ウイルスにさらされた24時間後には無菌状態であった。

Abstract
The application of antiviral coatings to masks and respirators is a potential mitigating step toward reducing viral transmission during the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic. The use of appropriate masks, social distancing, and vaccines is the immediate solution for limiting the viral spread and protecting people from this virus. N95 respirator masks are effective in filtering the virus particles, but they cannot kill or deactivate the virus. We report a possible approach to deactivating SARS-CoV-2 by applying an antimicrobial coating (Goldshield 75) to masks and respirators, rendering them suitable for repeated use. Masks coated with Goldshield 75 demonstrated continuous inactivation of the Alpha and Beta variants of the SARS-CoV-2 over a 3-day period and no loss of inactivation when stored at temperatures at 50 °C.
