Advances in Facemasks during the COVID-19 Pandemic Era

Abstract: The outbreak of coronavirus disease (COVID-19) has transformed the daily lifestyles of people worldwide. COVID-19 was characterized as a pandemic owing to its global spread, and technologies based on engineered materials that help to reduce the spread of infections have been reported. Nanotechnology present in materials with enhanced physicochemical properties and versatile chemical functionalization offer numerous ways to combat the disease. Facemasks are a reliable preventive measure, although they are not 1… Show more

“…Therefore, face masks are expected to (i) protect the wearer from contaminants such as particulates such as dust, bacteria, and sneeze droplets present in the surroundings while being permeable to air and provide blood splash resistance (for HCWs) to the wearer and (ii) prevent/ reduce expulsions of cough and sneeze by the wearer into the surroundings so as to keep the surrounding harm-free from infection especially during the pandemic situations . Some masks come with exhalation valves/ventilation fans [ 12 ] which reduce exhalation pressure drop and also reduce CO 2 accumulation. However, during the pandemic outbreak (such as COVID-19), masks with exhalation valves may leak the virus (such as SARS-CoV-2).…”

“…In most cases, a mask is also expected to be non-collapsible; therefore, a modacrylic layer is included to provide a tight fit around the wearer’s nose and mouth. Thus, most commercial masks are made from four- to five-layered fabric materials [ 12 ]. The layer contacting the skin should be soft non-woven fabric, providing comfort to the wearer, and hydrophilic in nature which holds cough droplets.…”

“…Sio et al [26] outlined how to realize non-disposable and highly comfortable respirators capable of light-triggered self-disinfection by combining bioactive nanofiber properties with stimuli-responsive nanomaterials. Karmacharya et al [27] discussed the manufacturing, practical applications, and anti-COVID-19 performance of novel masks. Melayil et al [28] investigated interactions of droplets over the most used surgical masks and studied the wetting signature, adhesion, and impact dynamics of water droplets and microbe-laden droplets on both sides of the mask.…”
