TL;DR: This communication demonstrates an approach to generate simple nanostructures with critical dimensions down to 30 nm over cm2-sized areas using composite PDMS masks that generated arrays of structures in photoresist with line widths as small as 30 nm.

TL;DR: In this article, a patterned polymer film was grown on SiO2/Si surfaces by a process starting with microcontact printing (μCP) of octadecyltrichlorosilane (OTS), formation of a monolayer derived from norbornenyl trichlorosa (Nbn-SiCl3) in areas not protected by OTS, activation of the surfaces derived from Nbn-siCl3 with a ruthenium catalyst, and surface-initiated ring-opening metathesis polymerization of derivatives of norbornene by the

TL;DR: This mechanism finds further support in the observations that rcaction of I with borohydride and oxygen in solutions containing2,2,6,6-tetramethylpiperidoxyl radical leads to good yields of thc prodr-rct of coupling of neophyl radical with the nitroxyl.

TL;DR: A simple method for fabricating electromagnets with micron-scale dimensions in poly(dimethylsiloxane) (PDMS) in close proximity (ca. 10-mm separation) to microfluidic channels to manipulate superparamagnetic beads magnetically is described.

TL;DR: A brief introduction to materials and techniques used for microfabrication can be found in this article, where the authors illustrate how non-traditional materials and methods for fabrication can yield simple, cost-effective routes to micro-systems and now they can expand the capabilities of these systems.
