From micro-pillars to wells and grooves,

PRIMO allows rapid prototyping of all the shapes you can imagine to create substrates adapted to each and every experiment!

PEG-biotin successively photopolymerized with PRIMO
PEG-DA mixed with PEG-FITC (green), PEG-TRITC (blue) or PEG-biotin successively photopolymerized with PRIMO. Streptavidin incubated afterward specifically stains the outer surface of the PEG-biotin hydrogel (red). Courtesy of C. Stoecklin and V. Viasnoff

And go even further with the microfabrication of complex structures in 3D!

The projection of gray levels by the PRIMO system allows for the microfabrication of complex structures such as stairs, linear or curved ramps, etc.

Pattern loaded into Leonardo software to do microfabrication in gray levels.
Optical profilometer analysis of the positive resin after illumination in gray levels by PRIMO and after development.

Experiment conducted with Institut Pierre-Gilles de Gennes.
