A paraffin-wax-infused porous membrane with thermo-responsive properties for fouling-release microfiltration

Rishun Li et al.

Summary: In this study, a temperature responsive paraffin-wax-infused membrane was developed to achieve both stability and slippery feature of lubricant. The paraffin wax could cover the entire membrane surface, including the micropore wall. When the paraffin wax was in liquid phase, the membrane surface exhibited a slippery state that resisted bovine serum albumin and bacterial adhesion. After three cycles of fouling and cleaning, the membrane with the optimum amount of paraffin wax showed significantly higher flux and flux recovery compared to the control membrane without paraffin wax.

Improved Recovery of Captured Airborne Bacteria and Viruses with Liquid-Coated Air Filters

Daniel P. Regan et al.

Summary: The COVID-19 pandemic has highlighted the importance of detecting airborne pathogens. This study presents composite air filters with a bioinspired liquid coating that enhances the removal of captured aerosolized bacteria and viruses for further analysis. The results show that coating the polytetrafluoroethylene (PTFE) and high-efficiency particulate air (HEPA) filters with liquid improves the detection rate of pathogens, while liquid-coated HEPA filters also increase the total number of recovered cells. However, coating cellulose nanofiber mats (CNFMs) filters did not improve the release rate or total number of captured cells. These findings suggest that liquid-coated filters can improve air sampling efforts, enhancing biosurveillance and early warning of global pathogens.
