Photolithographic surface micromachining of polydimethylsiloxane (PDMS).
A major technical hurdle in microfluidics is the difficulty in achieving high fidelity lithographic patterning on polydimethylsiloxane (PDMS). Here, we report a simple yet highly precise and repeatable PDMS surface micromachining method using direct photolithography followed by reactive ion etching (RIE). Our method to achieve surface patterning of PDMS applied an O(2) plasma treatment to PDMS ...
متن کاملMagnetite-doped polydimethylsiloxane (PDMS) for phosphopeptide enrichment.
Reversible phosphorylation plays a key role in numerous biological processes. Mass spectrometry-based approaches are commonly used to analyze protein phosphorylation, but such analysis is challenging, largely due to the low phosphorylation stoichiometry. Hence, a number of phosphopeptide enrichment strategies have been developed, including metal oxide affinity chromatography (MOAC). Here, we de...
متن کاملMold cleaning with polydimethylsiloxane (PDMS) for nanoimprint lithography
We present a simple and effective mold cleaning method for nanoimprint lithography. Polydimethylsiloxane (PDMS) prepolymer is spin-coated onto a contaminated imprint mold, thermally cured in ambient environment, and then peeled off afterwards. Contaminants of 100s m to sub-50 nm sizes are effectively cleaned within one cycle. During the cleaning process, a very thin PDMS film (1~2 nm) is unifo...
متن کاملCharacterization of polydimethylsiloxane (PDMS) properties for biomedical micro/nanosystems.
Polydimethylsiloxane (PDMS Sylgard 184, Dow Corning Corporation) pre-polymer was combined with increasing amounts of cross-linker (5.7, 10.0, 14.3, 21.4, and 42.9 wt.%) and designated PDMS1, PDMS2, PDMS3, PDMS4, and PDMS5, respectively. These materials were processed by spin coating and subjected to common micro-fabrication, micro-machining, and biomedical processes: chemical immersion, oxygen ...
متن کاملControlled Mechanical Cracking of Metal Films Deposited on Polydimethylsiloxane (PDMS)
Stretchable large area electronics conform to arbitrarily-shaped 3D surfaces and enables comfortable contact to the human skin and other biological tissue. There are approaches allowing for large area thin films to be stretched by tens of percent without cracking. The approach presented here does not prevent cracking, rather it aims to precisely control the crack positions and their orientation...
