A Nontoxic Battery with 3D-Printed Housing for On-Demand Operation of Microcontrollers in Microfluidic Sensors.

Microcontrollers have a low energy consumption and are convenient tools for the operation and readout of small lab-on-a-chip devices. The operation of microcontrollers for data collection and analysis is key for measurements and statistics in field experiments. However, for portable lab-on-a-chip or point-of-care systems in low-resource settings, the availability of energy sources is a bottleneck.

An indirect microfluidic flow injection analysis (FIA) system allowing diffusion free pumping of liquids by using tetradecane as intermediary liquid.

We suggest an indirect microfluidic flow injection analysis (FIA) system which uses tetradecane (C14H30) as intermediary liquid allowing the diffusion free handling of liquids in a fluidic system which is suitable for single use applications as required, e.g., biomedical applications.
