Low-Cost, Reliable and Large-Scale Virus Surveillance
VirusTrack Sampling Tube (preloaded with PSAP beads)
Encapsulation and Stablization of Viruses by PSAP Beads
The PSAP beads can extract and stabilize viruses in water samples for long-term storage at room temperature, thus bypassing the reliance on cold chain and enabling low-cost virus surveillance.
Potential Viral Pathogen Dissemination via Waterborne Pathways
Wastewater-based Epidemiology for COVID Surveillance
