Micropatterns of fluorescent fibronectin on glass surface
Micropatterning is the art of miniaturisation of patterns. Especially used for electronics, it has recently become a standard in biomaterials engineering and for fundamental research on cellular biology by mean of soft lithography. It generally uses photolithography methods but many techniques have been developed.
In cellular biology, micropatterns can be used to control the geometry of adhesion and therefore the orientation of the cell division axis.
Micropatterns can be made on a wide range of substrates, from glass to polyacrylamide and Polydimethylsiloxane (PDMS), allowing a lot of forces-related experiments.
Aerosol micropatterning for biomaterials uses spray microscopic characteristics to obtain semi-random patterns particularly well adapted for biomaterials.
