Avalon Nano-Biotech (HK) Limited has provided a donation to the ME department of 3 million Hong Kong dollars to support Prof. Wallace Leung in further developing and commercializing advanced air filtration nanofiber technologies to capture airborne viruses (e.g. COVID-19) and air pollutants. Facemasks production line has been established in Hong Kong utilizing nanofiber-based filter. The fiber diameter of the nanofiber is 1/10 of the commercially available microfibers in the market and therefore will have better filtration efficiency, especially for capturing airborne COVID-19 with only 60-140nm size, which can be attached to small particulates of the infected person or small droplets.

Besides, Prof. Leung will be involved in the filter projects with Avalon and MTR to improve the air quality for passengers riding the railway.
