Patent Application Titled "Paper-Based Sample Testing Devices And Methods Thereof" Published Online (USPTO 20230349008).

A patent application titled "Paper-Based Sample Testing Devices And Methods Thereof" has been published online. The inventors, David Erickson and Ruisheng Wang, have developed a user-friendly paper-based test that can visually detect test results, such as bacterial antibiotic susceptibility or the presence of COVID-19. The test utilizes on-chip paper microfluidics to enable testing of multiple samples with a single step. It has advantages such as low sample volume requirement and flexibility in incubation conditions. The method involves loading test and control samples, adding a supplementary liquid, incubating the chip, and examining the testing and control areas for a signal indicating the presence of the target. The inventors also propose a portable system that can process a larger number of tests, be cost-effective, and integrate with contact tracing apps to address the need for large-scale screening of asymptomatic carriers of COVID-19.
