NanoEarth Researcher Evaluating Respirators and Mask Materials

Since March, NanoEarth's Deputy Director Linsey Marr, an expert in the airborne transmission of infectious disease, has been testing the efficacy of sterilized N95 respirators and alternative mask materials in filtering out particles. The rapid science experiments conducted by Marr's team aim to help quantify how well these forms of personal protective equipment and homemade face coverings shield their wearers against COVID-19, especially in the face of shortages. This work has been featured extensively in news articles from various sources including several New York Times pieces and in a Virginia Tech news article. All of this work is being done in NanoEarth facilities.

TNF Supporting COVID-19 Sensor Research

Dr. Kyle Michelson is a research associate in the department of chemistry, UT Austin. He and his group are trying to develop a detector/sensor for the novel coronavirus which causes COVID-19. The research involves making a sensor with gold decorated with graphene, attachment of an antibody, and detection of a captured virus using Raman spectroscopy. The graphene quantum dots of the size of 2-3 nm required for the detection have been made, and TEM images have been obtained using one of the electron microscopy tools at TNF. 

Nanoearth snorkle

NanoEarth Supports Multiple COVID-19 Projects

NanoEarth co-PI and director of the Nanoscience degree program, Marc Michel, is using his expertise in inverse stereolithography, a type of additive manufacturing (3D printing), for two development purposes: 1) to design and fabricate 3D printed adapters that convert snorkel masks into reusable passive respirators with viral filters; and 2) to address shortages of COVID-19 test swabs. Testing includes mechanical properties and bench scale tests. Michel is working towards scaling up fabrication to meet regional testing needs. Additionally, NanoEarth Assistant Director for Innovation and Entrepreneurship, Matthew Hull, is leading an effort to develop a kit for rapidly converting surgical helmet systems into integrated powered air-purifying respirators (PAPRs). The PAPR retrofit kit is being evaluated for use in settings where direct exposure to CoVID-19 aerosols are likely. Hull’s team has fabricated a prototype and tested its performance using quantitative fit testing with the Naval Surface Warfare Center and a 100 nm diameter silicon dioxide nanoaerosol challenge with NanoSafe, Inc. The solution is being shared with healthcare providers around the US. These efforts are summarized in a Virginia Tech news article.

NCI-SW Laboratories Study the Germicidal UV Treatment of N95 Face Masks

Impact on Removing Nano-sized Particles During Reuse of Masks Investigated

The NCI-SW LCnano Center at ASU (with teams led by Profs. Westerhoff, Herckes and Sinha) is going beyond just building UV treatment systems capable of disinfecting N95 masks. Local physicians and first responders indicated they were unsure about the capability of disinfected masks to perform equally well during subsequent reuse. The center tested removal of new and UV disinfected (1 and 10 J/cm2) N95 masks. The results showed the new and disinfected masks both achieved  >97% removal of aerosolized particles in the 90 to 220 nm size range, similar to diameters of the coronavirus, and had no noticeable change in polymer structure or chemistry. This is reassuring, and the medical community have now asked for the UV treatment systems. At the same time the center has been considering feedback from the public, and been testing homemade face masks sewn using common cotton cloth fabrics. While not as efficient at capturing nanoparticles as the N95 masks, they remove between 30% to 60% of aerosolized particles in the 90 to 220 nm size range.

sewage monitoring

Monitoring for Coronavirus in Sewage led by NanoEarth Researchers

Building off of NanoEarth Co-PIs Peter Vikesland and Amy Pruden’s national and international network where they are using nanopore DNA sequencing to monitor for antibiotic resistance in sewage, they are building on the same network to monitor for SARS-COV-2 in sewage. This could provide a useful early warning system to identify communities shedding the virus and appropriately allocate resources. The initial network was built in part through NSF funding of a Partnership in International Research and Education (PIRE) grant (PIRE#1545756) and recently they were also awarded a Cyberinfrastructure for Sustained Scientific Innovation grant (CSSI#2004751) that will aid in building the appropriate cyberinfrastructure for this effort.
