Nanomaterials can be used to increase the performance and safety of PPE, such as air filters and masks. They may be used to not only capture aerosol droplets but also inactivate the virus upon contact with the surfaces of PPE. 

Opportunities for nanotechnology-based solutions to increase the efficiency and safety of air filter and mask devices include (i) improving particle capture and retention characteristics, particularly, in the 300 nm diameter size range; (ii) reducing the effects of exhaled humid air on particle redistribution; (iii) rapid inactivation of membrane-bound microbes including enveloped viruses upon capture; and (iv) thin, high-efficiency filtration media for personal masks that are able to be reused repeatedly without loss of efficiency (e.g., novel electrospun nanofibers).

Nanomaterials for COVID-19 Treatment 

Combining the excellent electrical and optical properties of nanomaterials with biological or synthetic molecules as receptors to detect selectively any kind of analyte, nanobiosensors are a valuable alternative to conventional diagnostic tools. 

- Graphene-based Field-Effect Transistor (FET) Biosensor

- Dual-Functional Plasmonic Biosensor

Paper/nanomaterial-based sensors, in general, and, particularly, NP-based lateral-flow devices that are observed with the naked eye or operated through a smartphone are now the most reported testing platforms for the analysis of COVID-19-related biomarkers. Nanopaper and nanochannels may also offer cost-efficient alternatives for detection of viruses and related biomarkers.
