Abstract:
The Coronavirus disease 2019 (COVID‐19) emergency has demonstrated that the utilization of face masks plays a critical role in limiting the outbreaks. Healthcare professionals utilize masks all day long without replacing them very frequently, thus representing a source of cross‐infection for patients and themselves. Nanotechnology is a powerful tool with the capability to produce nanomaterials with unique physicochemical and anti‐pathogen properties. Here, we outline how to realize non‐disposable and highly comfortable respirators with light‐triggered self‐disinfection ability by bridging bioactive nanofiber properties and stimuli‐responsive nanomaterials. The visionary road highlighted in this Concept is based on the possibility to develop a new generation of masks based on multifunctional membranes where the presence of nanoclusters and plasmonic nanoparticles arranged in a hierarchical structure enables the realization of a chemically‐driven and on‐demand anti‐pathogen activities. Multilayer electrospun membranes have the ability to dissipate humidity present within the mask, enhancing the wearability and usability. The photo‐thermal disinfected membrane is the core of these 3D printed and reusable masks with moisture pump capability. Personalized face masks with smart nano‐assisted destruction of pathogens will bring enormous advantages to the entire global community, especially for front‐line personnel, and will open up great opportunities for innovative medical applications.
