Nano-structured anti-reflective surfaces replicated by hot embossing
We developed a fabrication technique of anti-reflective structures for applications in the visible spectral range. The depth and duty cycle of the grating structures optimised for wavelengths around 500 nm were calculated using rigorous diffraction theory. We used electron-beam lithography for the manufacturing of linear and crossed grating patterns with pitches of 200 nm and various duty cycle...
متن کاملUltrasonic Hot Embossing
Ultrasonic hot embossing is a new process for fast and low-cost production of micro systems from polymer. Investment costs are on the order of 20.000 € and cycle times are a few seconds. Microstructures are fabricated on polymer foils and can be combined to three-dimensional systems by ultrasonic welding.
متن کاملWhole-Teflon microfluidic chips.
Although microfluidics has shown exciting potential, its broad applications are significantly limited by drawbacks of the materials used to make them. In this work, we present a convenient strategy for fabricating whole-Teflon microfluidic chips with integrated valves that show outstanding inertness to various chemicals and extreme resistance against all solvents. Compared with other microfluid...
متن کاملModeling of large area hot embossing
Today, hot embossing and injection molding belong to the established plastic molding processes in microengineering. Based on experimental findings, a variety of microstructures have been replicated so far using the processes. However, with increasing requirements regarding the embossing surface and the simultaneous decrease of the structure size down into the nanorange, increasing know-how is n...
متن کاملHot embossing for fabrication of a microfluidic 3D cell culture
Clinically relevant studies of cell function in vitro require a physiologically-representative microenvironment possessing aspects such as a 3D extracellular matrix (ECM) and controlled biochemical and biophysical parameters. A polydimethylsiloxane (PDMS) microfluidic system with a 3D collagen gel has previously served for analysis of factors inducing different responses of cells in a 3D microe...
