DNA, RNA and miniaturised sensors

How to detect microscopic amounts of genetic material in nanolitre volumes


Electronics and Computer Science


Many of us are aware of the need to make measurement of blood samples, or detect pollutants in rivers but the samples are always sent away to a lab for analysis with expensive and complex instruments. Behind the scenes, there are highly trained scientists and robots moving liquids and performing chemical analysis in test tubes. We have scaled down this entire process onto miniature microfluidics platforms. This technology is used to detect nucleic acids, DNA and RNA.

Why is this important?

With the increasing cost of healthcare and need for affordable environmental monitoring, microsensors can offer a low-cost simple alternative that be used in the field or a GP’s office.
