• Quick food allergy test - just a drop of blood

  Over 15 million people in Europe – including eight percent of all children - suffer from food allergies, and this number is growing steadily. Currently, children who portray mild symptoms may undergo a skin prick test that is not only lengthy but particularly painful and usually very traumatic. Researchers from the Positive consortium are about to change all that by putting a food allergy machine on every pediatrician's desk, a machine that produces test results in 15 minutes from a miniscule drop of blood.

• Cell-Ring - Close proximity photonic sensing of single-cell secretion

  Biological processes are dynamic and involve the interactions of cells with each other and their environment. To study the dynamics of cell signaling, measurements at the single cell level are necessary, since intra population variability and diffusion limitations tend to smear out the aggregate biochemical response of large cell populations. The aim of the Cell-Ring project is to create a nano-photonic sensor to study the biomolecule secretion of single cells in real-time. Duration: 2012-2017
