Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
We participate in the EU-COST actions MP1102: Coherent Raman microscopy (MicroCor) and CM1202: Supramolecular photocatalytic water splitting (PERSPECT-H2O)


Hyperspectral CARS imaging to detect cancerous tissue

  • Rick Krabbendam - PhD student

  • Using nonlinear optics such as CARS and SRS, we try to collect hyperspectral images of molecular vibrations in both healthy and cancerous tissue samples. Due to different concentrations of for example lipids and DNA in those tissues, spectra of both samples will differ. This hopefully enables an fast and relatively easy way to distinguish healthy tissue from cancerous tissue.
