Protein patterning by microcontact printing using pyramidal PDMS stamps
Micro-contact printing, μCP, is a well-established soft-lithography technique for printing biomolecules. μCP uses stamps made of Poly(dimethylsiloxane), PDMS, made by replicating a microstructured silicon master fabricated by semiconductor manufacturing processes. One of the problems of the μCP is the difficult control of the printing process, which, because of the high compressibility of PDMS,...
متن کاملHydrophilic elastomers for microcontact printing of polar inks.
A moderately hydrophilic, thermoplastic elastomer (poly(ether-ester)) was investigated as a stamp material for microcontact printing of a polar ink: pentaerythritol-tetrakis-(3-mercaptopropionate). Stamps with a relief structure were produced from this polymer by hot embossing, and a comparison was made with conventional poly(dimethylsiloxane) (PDMS) and oxygen-plasma-treated PDMS. It is shown ...
متن کاملAn alternative method for fabricating microcontact printing stamps
In this paper, we describe the development of microcontact printing stamps from photopatternable silicone. The photopatternability of this material enables convenient and fast stamp fabrication, and allows rapid patterning of substrates for culturing biological cells. Microcontact printing stamps made of the photopatternable silicone with linewidths as small as 2 lm were fabricated and reliable...
متن کاملSubmerged microcontact printing (SmuCP): an unconventional printing technique of thiols using high aspect ratio, elastomeric stamps.
A technique for microcontact printing of thiols in liquid media is presented. Elastomeric poly(dimethyl siloxane) stamps are used to pattern gold surfaces with thiol-based self-assembled monolayers. The liquid (water in this case) has been used as an incompressible support and, advantageously, also acts as a medium in which alkylthiol ink molecules are poorly miscible. Consequently, we have bee...
متن کاملNon-Photolithographic Methods for Fabrication of Elastomeric Stamps for Use in Microcontact Printing
Thispaperdescribes severalmethods that generatepatterned relief structures for casting the elastomeric stamps required in microcontact printing (μCP). The relief structures include the following: (1) patterns etched in thin films of silver (200 nm thick) with printed SAMs of hexadecanethiolate as resists; (2) patterned polymeric structures assembled on the surface of a thin film of silver (or g...
