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)


Characterization of Nanostructured Solar-to-Fuel devices

  • The objective of our research is the design, synthesis, characterization and optimization of nanostructured solar-to-fuel devices based on silicon micro/nano pillars functionalized with WO3-based photocatalysts. A typical example of our nanostructures is shown in Figure 1.
