High‐Throughput Contact Flow Lithography
High-throughput fabrication of graphically encoded hydrogel microparticles is achieved by combining flow contact lithography in a multichannel microfluidic device and a high capacity 25 mm LED UV source. Production rates of chemically homogeneous particles are improved by two orders of magnitude. Additionally, the custom-built contact lithography instrument provides an affordable solution for p...
متن کاملContact Thermal Lithography
Contact thermal lithography is a method for fabricating patterns based on thermal effects. In contrast to photolithography, where resolution is limited by the wavelength of light used in the exposure process, thermal lithography is limited by thermal diffusion. A traditional metal-glass photomask is brought into contact with a wafer coated with a thermally sensitive polymer. The mask-wafer comb...
متن کاملHigh-throughput Synthesis of Encoded Hydrogel Particles for Biosensing Using Contact Flow Lithography
We report an automated cost-efficient method for the high-throughput fabrication of graphically encoded hydrogel microparticles for use in multiplexed biosensing. By combining automated flow lithography in a multichannel microfluidic device with contact lithography and a high capacity 1-inch UV source, we improve our production rate of chemically homogeneous particles by at least two orders of ...
متن کاملTalbot Lithography as an Alternative for Contact Lithography for Submicron Features
In this paper we show that using optical photolithography it’s possible to obtain submicron features for periodic structures using the Talbot effect. To use the Talbot effect without the need of an absolute distance measurement between the mask and the wafer we integrate over several exposures for varying wafer mask distances. Here we discuss the salient features of ‘integrated Talbot lithograp...
متن کاملStop-flow lithography in a microfluidic device.
Polymeric particles in custom designed geometries and with tunable chemical anisotropy are expected to enable a variety of new technologies in diverse areas such as photonics, diagnostics and functional materials. We present a simple, high throughput and high resolution microfluidic method to synthesize such polymeric particles. Building off earlier work that we have done on continuous flow lit...
