In this study, a simple and reliable method for substrate prepatterning by soft imprinting, using a diffusion-reaction-controlled wet chemical etching method, is developed thus avoiding the use of sophisticated device fabrication procedures.
The first approach is to pattern the TiO2 film by various lithographic methods such as soft imprinting [1], polystyrene sphere templating [2 4], 3-dimensional holography [5], and glass texturing [6, 7].
In addition to self-assembly approaches, the introduction of non-conventional top-down techniques including IL, soft imprinting, and DW, and hybrid techniques overcome the tendency for inadvertent defect formation during self-assembly as well as the ability to precisely design a particular geometry and composition.
This study developed the magnetic fluid bag micro-roll imprinting system equipment, and compared the roll imprinting behavior of the general rigid roller and soft roller imprinting systems.
Soft mold imprinting provides a simple and good alternative to the conventional wafer imprinting as multiple copies of the soft mold are easily produced using a simple and low-cost method [59], besides the fact that the low surface energy of PDMS allowed it to be used directly for imprinting without the need for anti-stick layers [16, 58].
ROBIN MORGAN New York To the Editor: I enjoyed Winterson's thoughtful reappraisal of "Tropic of Cancer" but wanted to respond to her offhand reference to Henry Miller's first publisher as a "soft-porn imprint".
First published in Paris in 1934 by Obelisk, a soft-porn imprint, it had been banned as obscene in America until a landmark legal victory overturned the ban, allowing Grove to print it legally in 1961.
And there is much beauty on every page — the "sooty tapestry" of a fellow-traveller's hairy torso, or Pronek's skin first thing in the morning, "soft, with crease imprints, the fossils of slumber".
The flexibility of soft templates allows imprinting over uneven substrates but today they suffer from laterally varying residual layer thickness in-between the imprinted structures, which cannot be removed by conventional processes.
Additionally, SAMs were used in conjunction with soft lithographic techniques to imprint substrates with specific patterns, resulting in patterned DNA complex deposition and transfection, with transfection efficiencies in the patterns nearing 40%.
