课题组We are a research group in the State Key Laboratory of Bioelectronics at Southeast University, China. We are developing the basic science and technology for fabricating microanalytical point-of-care testing (POCT) devices using new materials and fabrication techniques.

The material we are currently interested in is simply paper or cellulose-based materials. When I was a PhD student under the supervision of Prof. Richard Crooks at UT Austin, we developed a method using the principle of origami (paper folding) for fabricating three-dimensional paper analytical devices. The devices are now called oPADs (origami paper analytical devcies, J. Am. Chem. Soc. 2011, 133, 17564; Angew. Chem. Int. Ed. 2012, 51, 6925). These oPADs are extremely cheap (e.g. several cents/device), but can be used for high-throughput multiplexed assays and even can be connected to an iPhone or Android phone to display the assay results. One prototype of the oPADs was collected by the Stetten Museum of National Institute of Health (link to the museum).

The long-term goal of our group is to provide innovative solutions to mobile health (mhealth) and medical diagnostics in under-developed areas.
