3D microelectrode chip helps soil nutrient analysis

Researchers have developed a novel microfluidic chip with capacitively coupled contactless conductivity detection (C4D) integrated 3D microelectrodes to rapidly and quantitatively determine abundant nutrient ions in soil.

Microfluidics

Microfluidics deals with the behavior, precise control and manipulation of fluids that are geometrically constrained to a small, typically sub-millimeter, scale. Typically, micro means one of the following features:

It is a multidisciplinary field intersecting engineering, physics, chemistry, microtechnology and biotechnology, with practical applications to the design of systems in which such small volumes of fluids will be used. Microfluidics emerged in the beginning of the 1980s and is used in the development of inkjet printheads, DNA chips, lab-on-a-chip technology, micro-propulsion, and micro-thermal technologies.
