Handheld Microfluidic Filtration Platform Enables Rapid, Low-Cost, and Robust Self-Testing of SARS-CoV-2 Virus (Small 52/2021)

ABSTRACT

COVID-19 Diagnostics In article number 2104009, Jiang Xu, Yan Zhang, Taotao Lao, and co-workers present a handheld microfluidic filtration platform that enables rapid, low-cost and robust self-testing of the SARS-CoV-2 virus. The cover design emphasizes its important advantages (1) Equipment-free handheld injection, represented by the hands manipulation;(2) Visible and easy readout a Taichi diagram is used to distinguish the negative/positive results, which is in line with the meaning of Taichi (Yin/Yang) in traditional Chinese culture. The Taichi eyes are filled with illustrational structures of negative/positive nanocomplexes;(3) Reusable chips the flow arrows at both inlet and outlet indicate that the chip can be repeatedly cleaned and injected.
