Mechanical interlock effect by micro scale pattern can be increased by nano scale surface morphology effect promoting additional adhesion strength at the interfaces.
In this paper, soft lithography techniques were applied to microfabricate polydimethylsiloxane molds with precisely controlled micro-scale patterns.
Milli- to micro-scale patterns can be designed to create a fast, cost-effective device that uses small amounts of reagents and samples.
Two different types of micro-scale patterns, including a sharp microprismatic pattern and a smooth microlens pattern, were embossed on the surface of the PVAc/PU multilayer films by a PDMS replica mold using the soft lithography method.
Hong et al. prepared a direct mixture of polytetrafluoroethylene (PTFE) nanoparticles into SU-8, spin-coated the PTFE-SU-8 nano-composite on transparent substrates such as glass and polymers, and photo defined micro-scale patterns with a minimum feature size of 50 μm [33].
The EC has long been used to study micro-scale patterns of evolution and several works have found differences in interslope biodiversity across life involving bacteria, fungi, plants, and animals [ 26].
Compared with photolithography, this has the advantage that the PDMS mask can be re-used and has a micro-scale pattern.
Plasma processes of interest for tissue engineering, biosensors and related applications have been utilized for micro-scale patterning polymers with 'physical masks'.
The single quantum sensitivity (zero-dark current noise level) combined with per-pixel spectrometry and micro-scale pattern recognition analysis of single particle tracks enables the composition (particle type) and spectral characterization (energy loss) of mixed radiation fields to be determined.
The resulting three-dimensional whole-cell views indicate that the arrangement and dynamics of microtubules and actin are the major contributors to meso- and micro-scale patterning of silica in diatoms.
Micro- and nanometer scale patterns can be obtained by photolithography [1 4], electron beam lithography [5, 6], soft lithography [7], micro-contact printing (μCP) [8 11].
