Subnanometer replica molding of molecular steps on ionic crystals. [PDF]
Nano Lett, 2010 Replica molding with elastomeric polymers has been used routinely to replicate features less than 10 nm in size. Because the theoretical limit of this technique is set by polymer-surface interactions, atomic radii, and accessible volumes, replication at subnanometer length scales should be possible.

Fabrication, densification, and replica molding of 3D carbon nanotube microstructures. [PDF]
J Vis Exp, 2012 The introduction of new materials and processes to microfabrication has, in large part, enabled many important advances in microsystems, lab-on-a-chip devices, and their applications. In particular, capabilities for cost-effective fabrication of polymer microstructures were transformed by the advent of soft lithography and other micromolding ...

Polydimethylsiloxane based dry adhesives produced using a replica molding technique. [PDF]
RSC AdvA replica molding technique is used to produce micron-sized pillars on the surface of polydimethylsiloxane (PDMS). The shear adhesion strength of the sample is determined to be 0.12 N cm−2.

Replica-molded high-Q polymer microresonators [PDF]
Optics Letters, 2004 Ultrahigh-Q microtoroids on a chip are applied as replication masters to demonstrate replica-molded high-Q microresonator arrays. Replica Q factors are nearly material loss limited, affirming the integrity of the replication process, and are as high as 5 x 10(6), or nearly a factor of 40 greater than previous polymer-based devices.

Polycarbonate Masters for Soft Lithography
Micromachines, 2021 Fabrication of microfluidic devices by soft lithography is by far the most popular approach due to its simplicity and low cost. The approach relies on casting of elastomers, such as polydimethylsiloxane (PDMS), on masters fabricated from photoresists on ...

Diffractive lens fabrication by replica molding [PDF]
Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Technical Digest (IEEE Cat. No.01CH37170), 2001 Summary form only given. Diffractive lenses and 2-D gratings were fabricated using electron-beam lithography and replica molding. With electron-beam lithography, feature sizes smaller than 60 nm can be achieved. We demonstrate that we can achieve similar feature sizes with replica molding.

A Bio‐Mimetic Leaf Wetness Sensor from Replica Molding of Leaves
Advanced Sensor Research, 2023 Plant diseases cause hundreds of billions of dollars in global crop production each year. Many plant diseases develop when pathogens germinate and proliferate in the fertile environment of excess water on the leaf surfaces.

Gaining Micropattern Fidelity in an NOA81 Microsieve Laser Ablation Process
Micromachines, 2020 We studied the micropattern fidelity of a Norland Optical Adhesive 81 (NOA81) microsieve made by soft-lithography and laser micromachining. Ablation opens replicated cavities, resulting in three-dimensional (3D) micropores.
