Seller: borna_vista (638) 100%, Location: Fremont, California, Ships to: US, Item: 173226313401 Information Very RARE Silver Nanowire Patterning Photomask Dimension: 2 ½” by 2 ½” inches Condition: Vintage Truly a great collector’s item. Technical Information Silver Nanowire Patterning Method Based on Poly (Ethylene Glycol) Photolithography and Its Application for Soft Electronics: Fabrication of AgNW patterns on various substrates via two consecutive solution-only processes. (A) Schematic illustration for fabrication of AgNW-based micropatterns on the hydrogel: (i) AgNW dispersion solution was spin-coated on a glass substrate; (ii) PEG photolithography process using UV light via a photomask; (iii) peeling off of the PEG hydrogel layer by detaching the silane-treated cover glass to construct AgNW patterns on the glass substrate; (iv) second gel precursor solution (agarose or polyethylene glycol, or polyacrylamide) was poured onto the AgNW-patterned glass, and a second gelation process was conducted; and (v) peeling off of the second gel layer and transfer of the AgNW patterns from the glass to the hydrogel substrate. (B) Photographs showing the procedure used to fabricate AgNW-based micropatterns: (a) peeling off of the PEG hydrogel layer by detaching the silane-treated cover glass; (b) AgNW micropatterns on the glass substrate; (c) peeling off of the second gel layer; and (d) transfer of the AgNW patterns from the glass to the hydrogel substrate. Recent advancements in the fabrication of flexible and stretchable microelectrodes based on various conductive materials (i.e. graphenes, carbon nanotubes (CNTs), metals, conductive polymer, etc.) and novel patterning techniques have led to the development of novel bioelectronics such as wearable and implantable devices. In particular, hydrogel-based, molecularly-permeable microelectrodes are potentially valuable for soft bioelectronics applications. This is the case because hydrogels are well suited for interfacing with dynamic human tissues due to their biocompatibility, molecular permeability, and tunable mechanical properties. Additionally, microelectrodes are amendable to rapidly detecting disorder in biological signals originating from various diseases. Despite the innovative utilization of hydrogel-based microelectrodes, there are fewer reports investigating hydrogel-based microelectrodes compared to glass- or silicone-based microelectrodes. This discrepancy is related to the difficulty associated with constructing conductive patterns on wet hydrogel substrates. Payment PayPal is accepted for all transactions.
