Abstract
A method of preparing a patterned micro-contact printing stamp for micro contact printing including the making of a submaster of e.g. epoxy, against which a micro-contact printing stamp from polydimethylsiloxane or other stamp forming material can be formed. The micro-contact printing stamp can then be exposed to an inking material while the micro-contact printing stamp is still against the submaster, resulting in a micro-contact printing stamp capable of making numerous impressions before the inking material is exhausted.
Claims22
A method of preparing a patterned micro-contact printing stamp for micro contact printing, comprising:
- providing a master of the desired pattern;
- applying stamp forming material to the master;
- hardening the stamp forming material to form a micro-contact printing stamp;
- and
- placing a quantity of an inking material on the micro-contact printing stamp and exposing the micro-contact printing stamp to the inking material while the micro-contact printing stamp is still in contact with the master, wherein the inking material comprises chemical species that form self-assembled monolayers.
A method of preparing a patterned micro-contact printing stamp for micro contact printing, comprising:
- providing a master of the desired pattern;
- applying negative-making material to the master to obtain a negative of the desired pattern;
- preparing a submaster from the negative;
- applying stamp forming material to the submaster;
- hardening the stamp forming material to form a micro-contact printing stamp;
- and
- placing a quantity of an inking material on the micro-contact printing stamp and exposing the micro-contact printing stamp to the inking material while the stamp is still against the submaster, wherein the inking material comprises chemical species that form self-assembled monolayers.
