Microfluidic fuel cells on paper

Jennifer Newton writes about a HOT EES article in Chemistry World

Instrument-free point-of-care diagnostic devices could be taken to the next level with the development of microfluidic fuel cells on paper.

Paper is cheap, biodegradable, thin and flexible, making it an ideal base material for single-use tests. The paper-based microfluidic fuel cells created by Juan Pablo Esquivel, at the Barcelona Microelectronics Institute of the National Microelectronics Centre, IMB-CNM (CSIC), in Spain, and colleagues, were inspired by the convenience and simplicity of lateral flow test strips – pregnancy tests are probably the most well-known example of these – and take advantage of capillary diffusion to transport reactants without external pumps.
