Microcontact printing (p-CP) is another technique that can be used to place NAs onto different target surfaces. This technique makes use of an elastomeric stamp of polydimethylsiloxane (PDMS) and produces features with lateral resolution in the submicrometer range. The PDMS stamp is topographically structured by casting a PDMS prepolymer against a 3D master. The stamp is then inked with the molecules of interest, rinsed with buffer, blown dry under a stream of nitrogen, and then used to print the material onto the substrate surface (see Fig. 20).

Microcontact printing (pCP) is a technique that uses an elastomeric stamp with relief on its surface to generate patterned SAMs on the surface of both planar and curved substrates [87,88]. SAMs are highly ordered molecular assemblies that form spontaneously by chemisorption of functionalized long-chain molecules on the surfaces of appropriate substrates [79,89]. Well-established systems of SAMs include alkanethiolates on coinage metals (Au, Ag, Cu) [90] alkyl-siloxanes on hydroxyl-terminated surfaces (Si/Si02, glass) [91] carboxylic and... 

Microcontact printing (pCP, see Fig. 10 for an example) has been used for the spatially resolved modification of gold, silver, or titanium surfaces with SAMs of methyl-terminated alkanethiolates, which favor protein adsorption [99-101], Backfilling around the patterned protein-attractive islands was performed by a subsequent self-assembly of an ethylene-glycol-terminated alkanethiol. In a next step, the hydrophobic methyl-terminated SAMs were covered by adsorbed FN or other cell-adhesion-mediating proteins.
