Microcontact Printing of Self-Assembled Monolayers

Moreover, its elastic properties allow for conformal surface contact with other materials over relatively large areas, and make operations, such as printing and demolding, easy [2]. 

The harder thin layer then exhibits the patterned structures, whose size can be reduced while minimizing deformations. Another possibility is the use of a metal lamella covered with a thin structured PDMS ]17]. Because of the stiffness of the metal, roof collapse between the structures is reduced still, the metal is flexible enough to compensate macroscopic inhomogenities and to pattern curved surfaces ]11]. 

The main advantages of p,CP are that is an easy, inexpensive, readily accessible processing method. Moreover, it is possible to use it on nonplanar surfaces and to generate three-dimensional structures furthermore, it is a parallel method that allotvs the patterning of large areas even with nanometer size features.

PET and poly(ethylene naphthalate) (PEN) were activated using oxygen plasma [8]. Patterns of self-assembled monolayers of trichlorosilane initiators were then deposited using microcontact printing. Microstructured thermoresponsive poly(iV-isopropylacrylamide) (PNIPAM) brushes were generated by ATRP. 

Microcontact printing (12-14) of self-assembled monolayers was carried out using a patterned polydimethylsiloxane stamp to print a 2mM ethanolic solution of the relevant thiol onto gold-coated silicon substrates.

Microcontact Printing. An ink of alkanethiols is spread on a patterned PDMS stamp. The stamp is then brought into contact with the substrate, which can range from coinage metals to oxide layers. The thiol ink is transferred to the substrate where it forms a self-assembled monolayer that can act as a resist against etching.
