Photonics lab-on-chip

research research-tracks lab-on-chip

The B-PHOT photonics lab-on-chip team focuses on multifunctional opto-microfluidic systems that can combine optical absorption, fluorescence, surface-plasmon-resonance, and/or Raman spectroscopy in combination with optical trapping as on-chip optical detection techniques. These photonic labs-on-a-chip are fabricated in-house using B-PHOT’s highly advanced prototyping and pilot-line for polymer and glass micro-opto-fluidic components. Currently the team develops labs-on-chip for measuring the concentration of hazardous substances such as aflatoxins in food, the detection of pathogens in drinking water such as E-Coli and Salmonella, the authentication of olive oils, beer, honey or other products, and the testing of medical drugs using human-organs-on-chip to minimize the use of test-animals.

3D printing of microstructures for labs-on-chips

Our labs-on-chips can also be foreseen of scaffold structures to facilitate cell growth, which can then result in the realization of organs-on-chip. As an example, seeding and culturing hepatocyte-like cells in 3D scaffolds allow for the creation of an artificial liver on chip, which can then be used as an in-vitro testing platform for drug testing. By putting the cells in a 3D scaffold with microfluidic flow, one creates an environment wherein the cells are organised in a human-relevant configuration and will allow the model to be much more representative than cell cultures in Petri dishes without flow. In time, we want to contribute to reducing the need for using animals for drug testing.

Another important feature that can be added to microfluidic labs-on-chips by means of laser direct writing is nanostructured surfaces for surface-enhanced Raman spectroscopy (SERS). Since the intensity of Raman scattering is very low, working with SERS surfaces allows to strongly increase the Raman signal to allow a better detection.
