Abstract:
The present invention is directed towards a method and means for molecularly patterning a surface to promote the patterned attachment of a target adherent. In some preferred embodiments the target adherent is a biological cell, but it can more generally be a biological or chemical species for which attachment at specific sites is desired. The method generally involves using a stamp to microcontact print a first type of molecule on the surface. With the stamp remaining in situ, the process then involves fluidic patterning of a second type of molecule through selected openings defined by selected recesses in the stamp and the surface itself. The second type of molecule should have an adhesion property relative to the target adherent that is complementary to that of the first type of molecule. The stamp is removed only after both the first and second types of molecules have been transferred to the surface.
