Fabrication of conical microneedles array using photolithography
Background and Aim: Microneedle technology has led to huge changes in the field of drug delivery medicine. Using microneedles, the drug can be injected locally, painlessly, and in very low and controlled doses with high precision. Local drug delivery through the skin with microneedles has many advantages over other methods of drug delivery. In this method, the drug does not enter the gastrointe...
متن کاملA scalable fabrication process of polymer microneedles
While polymer microneedles may easily be fabricated by casting a solution in a mold, either centrifugation or vacuumizing is needed to pull the viscous polymer solution into the microholes of the mold. We report a novel process to fabricate polymer microneedles with a one-sided vacuum using a ceramic mold that is breathable but water impermeable. A polymer solution containing polyvinyl alcohol ...
متن کاملLithography Assisted Fiber-Drawing Nanomanufacturing
We present a high-throughput and scalable technique for the production of metal nanowires embedded in glass fibres by taking advantage of thin film properties and patterning techniques commonly used in planar microfabrication. This hybrid process enables the fabrication of single nanowires and nanowire arrays encased in a preform material within a single fibre draw, providing an alternative to ...
متن کاملRapid local anesthesia in humans using minimally invasive microneedles.
OBJECTIVE This study tested the hypothesis that minimally invasive microneedles cause less pain during injection of lidocaine, but induce local anesthesia in humans with the same rapid onset and efficacy as intradermal lidocaine injection using hypodermic needles. METHODS This study was a randomized, single-blinded, within participants, controlled design. Hollow, 500-μm long microneedles were...
متن کاملInvestigation on fabrication of nanoscale patterns using laser interference lithography.
Nanoscale patterns are fabricated by laser interference lithography (LIL) using Lloyd's mirror interferometer. LIL provides a patterning technology with simple, quick process over a large area without the usage of a mask. Effects of various key parameters for LIL, with 257 nm wavelength laser, are investigated, such as the exposure dosage, the half angle of two incident beams at the intersectio...
