Program 3: Microfluidics and miniaturised separation technologies

The following projects are undertaken in the research area of
Program 3: Microfluidics and miniaturised separation technologies


Microreactors for organic synthesis

In this project microreactors are developed for heterogeneous catalysis. Ligands for palladium are attached to polymer monolithic supports inside capillaries or microchannels and loaded with Pd. The performance of these microreactors is evaluated using Suzuki-Miyaura, Sonogashira and Heck reactions.



Contactless conductivity detection

Contactless conductivity detection is an universal detection technique that can be incorporated in microfluidic devices by integration of detection electrodes. Different detector designs are compared based on sensitivity, noise level and linearity of the detector response.

Participants: Rosanne Guijt

Direct writing lithography





Novel approach to study mechanisms of Na+ transport in plants using lab on a chip technology





CE separation of drugs with Laser Induced Fluorescence (LIF) detection

A LIF detection system was build in-house. Using in-house made microdevices (PDMS/glass hybrids), CY-5 labeled analytes are separated by CE and detected using the LIF detector. Results form the microchips are compared with results from capillary CE with LIF.



Integrating polymer electrodes

In collaboration with the Dalian Institute for Chemical Physics (DICP, China), a novel and cheap method is developed for integrating polymer electrodes on Lab-on-a-Chip devices.
