Building a biochemistry lab on a chip

Miniaturized laboratory-on-chip systems promise rapid, sensitive, and multiplexed detection of biological samples for medical diagnostics, drug discovery, and high-throughput screening. Using micro-fabrication techniques and incorporating a unique design of transistor-based heating, researchers at the University of Illinois at Urbana-Champaign are further advancing the use of silicon transistor and electronics into chemistry and biology for point-of-care diagnostics.

The InLiveTox project explores the impact of nanoparticles on the immune system

The InLiveTox project, which has been funded by the EU over the past three years, has significantly advanced the capability of in vitro testing of nanoparticles. The project focused on the impact of nanoparticle exposure on the gut, cardiovascular system and liver. Exposure via ingestion is particularly relevant due to the inclusion of nanoparticles in food, food packaging and oral medicines.
