Chemical modification of SU-8 gives rise to produce micro optical wave guides owing to changes in the refractive indices by insert nanoparticales and using thermal processing.

Our product can be used for Micro-mirror, Beam splitters, Dielectric layer, Spacer for lenses , Photonique Crystal, Inkjet printing of micro lenses. SU-8 wave guides have high thermal stability and very good adhesion properties to various substrates materials as well as good transparency values in the visible wavelength range that give you the possibility to change the refractive indices to design different types of wave guides devices.

In some case it is interesting to bring integrated microchannels to the different electrodes. Gersteltec product can be use for this topics as Organotypic brain slice cultures, Dissociated neuron Cultures and  Heart muscles cells (courtesy of Qwane Biosciences and Guillaume Petitpierre LMIS4 EPFL),

These watch industry is taking advantage from Gersteltec technology to produce all types of complex and innovative movements and components, from springs to balance wheels, spirals and bridges, gears and cases. The accurate and complex 3D shapes that can be ensured, the tribological behavior of the materials, the transparency and the esthetical effects that can be created on the pieces are only some of the main advantages of the technique (resolution typically of about 1–2 μm in plane and aspect ratio of 10), (courtesy of SURON Israel and Mimotec Switzerland).

Microfluidics refers with the behavior and manipulation of precise amounts of fluids that are geometrically constrained to a small sub-millimeter channels which allow different analytical measurement technique as DNA chips, lab-on-a-chip technology, integrated electrodes on chips, micro-propulsion, energy generation and micro-thermal technologies. Microfludics are being used in BioMEMS applications
