The machine for your microprinting process

DESCRIPTION
A low cost fully automated instrument (microcontact printer) has been developed in the laboratory. It allows the chemical patterning of parts (silicon, glass, polymer) at very high resolution for the first time (400 nm resolution, for example to make Au optical graftings on polymer parts). High resolution printing is achieved thanks to a patented monitoring of the load on the stamp during contact printing.
The machine allows also reproducible printing of superimposable patterns with a series of chemical products (for example to silanize microfluidic devices and print biomolecules at define locations).

STAGE OF DEVELOPMENT
A second improved functional prototype has been made by the laboratory.
