Multilevel self-aligned microcontact printing system.
A multilevel microcontact printing (μCP) system that avoids the use of optical alignment and precision manipulation equipment is demonstrated. Most of the complexity is transferred to the poly(dimethylsiloxane) (PDMS) stamp itself by forming the features, a mechanical self-alignment mechanism, and an elastic membrane by wafer scale replica molding on a Si master. Flexible 50-μm-thick photoetche...
متن کاملPatterning small-molecule biocapture surfaces: microcontact insertion printing vs. photolithography.
Chemical patterns prepared by self-assembly, combined with soft lithography or photolithography, are directly compared. Pattern fidelity can be controlled in both cases but patterning at the low densities necessary for small-molecule probe capture of large biomolecule targets is better accomplished using microcontact insertion printing (μCIP). Surfaces patterned by μCIP are used to capture biom...
متن کاملSilicon microcontact printing engines
A method of self-aligned, microcontact printing that avoids the need for dedicated alignment and stamping equipment is demonstrated. Complete miniature print engines combining elastically supported print heads with alignment structures that mate with corresponding features on etched substrates to allow mechanical registration are constructed from silicon parts. The impression can be transferred...
متن کاملBiocatalytic microcontact printing.
Immobilized biocatalytic lithography is presented as an application of soft lithography. In traditional microcontact printing, diffusion limits resolution of pattern transfer. By using an immobilized catalyst, the lateral resolution of microcontact printing would depend only on the length and flexibility of the tether (<2 nm) as opposed to diffusion (>100 nm). In the work, exonuclease reversibl...
متن کاملMicrocontact Printing With Octadecanethiol
We investigate various alkanethiol self-assembled monolayer inks for microcontact printing patterns on gold substrates. Our research compares hexadecanethiol with an alkanethiol of higher molecular weight, octadecanethiol. Transport mechanisms of alkanethiols along the gold surface and through the ambient are highly dependant upon the molecular weight of the thiols used, and thus are of particu...
