Medical masks proved effective in protecting against the virus during the Covid-19 pandemic. However, conventional masks are poorly biodegradable. For this reason, the presented paper produced environmentally friendly chitosan/silver/plant fiber membranes for masks, which also exhibited antibacterial and thermal properties.
The corona virus disease COVID-19 has changed the world. To combat the pandemic, researchers and companies around the world are working to develop vaccines and medicines. Chitosan also has potential in the area of vaccine development and functionalization of protective equipment such as respirators. We have prepared summaries of recent publications on chitosan as an aid in the fight against corona.
Chitosan is a promising drug delivery system for pulmonary applications and is therefore of particular interest for vaccine development in the Corona Pandemic. The biodegradable and biocompatible polymer's mucoadhesive, permeation-increasing and site-/cell-specific properties are useful in this context. Nanocarriers based on various microencapsulation and micro-nano mixing systems have already been developed. The aerodynamic character is important to enable efficient pulmonary aerosol formation and inhalation. In this article we present research on chitosan as pulmonary particulate anti-infective drug carrier.
