Sensitive, Rapid, Low-Cost, and Multiplexed COVID-19 Monitoring by the Wireless Telemedicine Platform

To prevent the more severe spread of COVID-19 infections, sensitive, rapid, low-cost, and multiplexed detection is critical. Recently, Gao et al. reported a laser-engraved graphene-based wireless device to monitor multiple biomarkers from human biofluids, allowing for high-frequency self-testing of COVID-19 with high accuracy and low cost.
