Microcontact printing (µCP) is a versatile soft lithographic technique that can be used to ‘print’ (bio)molecules with a pattern on the surface of a substrate (such as glass, silicium, gold etc). The patterning is carried out through ‘inking’ a polydimethylsiloxane (PDMS) stamp containing the relief pattern and then ‘stamping’ the substrate with the PDMS stamp.

µCP ensures high spatial control of the surface functionalization down to the nano-scale, which allows various applications ranging from FRET sensors to flow cell applications. Current research focusses both on the formation of new functionalized surfaces and the application of these surfaces in, e.g., biomedical or catalysis applications.
