Deposition of colloidal quantum dots by microcontact printing for LED display technology
… previous QD-LEDs'. Through a modification of the polydimethylsiloxane (PDMS) stamp with a parylene-C coating, quantum dots solvated in chloroform were successfully inked and stamped onto various substrates, including different molecular organic layers. The ability to control the placement and the …

Printed electronics and micro-electromechanical systems
… actuators is described In liquid embossing a polydimethylsiloxane (PDMS) stamp with bas-relief features is brought into intimate contact with a thin liquid film such as a metal or semi-conductor nanoparticle colloid, spin-on-glass, or polymer to create patterns as small as 100 nm. A simulation …

The effect of P-selectin pattern width on HL-60 cell rolling behavior
… was produced via microcontact printing using a polydimethylsiloxane (PDMS) stamp. HL-60 cells were flowed across the pattern using a syringe pump at low and high volume flow rates, and the lengths of the cells' tracks along the edge and velocities along the edge were obtained using a designed …

Elastomeric Stamping: Design Considerations for Long -Term Maintenance of Neuronal Networks
… new patterning process uses a microfabricated polydimethylsiloxane (PDMS) stamp with micrometer length features to transfer multiple types of biomolecules to surfaces prepared with (3-aminopropyl)silane (3-APS) or (3-mercaptopropyl)silane (3-MPS) using glutaraldehyde or …

3D integration of micro- and nanostructures into bio-analytical devices
… takes advantage of an intermediate thin flexible stamp such as PDMS from soft lithography and a hard mold such as brass from hot embossing process. However, the use of a thin intermediate polydimethylsiloxane (PDMS) stamp inevitably causes dimensional changes in the 3D molded channel, with respect …

Microassembly via polymeric stamp-based transfer printing
… to complement conventional microfabrication. Polydimethylsiloxane (PDMS) or shape memory polymer (SMP) as “stamp material,” working in conjunction with 3-dimensional positioning stage, provides reliable and precise relocation method of a micro-scale object for device assembly. Theoretical …
