Despite of wide range of potential applications, 3D functional microparticles with nanostructures cannot be prepared readily by conventional synthetic schemes. Here, we will consider two different routes for the microparticles: namely, self-organization of photo-responsive complex colloids inside microfluidic devices and holographic lithography directly on pre-patterned microfluidic channels. The...
An integrated pressure/flow sensor using a direct UV written planar Bragg grating situated inside a flexible diaphragm of thickness 200 mum has been fabricated. The diaphragm is created by etching away the underlying silicon support.
A microstructured arrayed microfluidic waveguide structure for infrared radiation focussing and transfer is proposed and demonstrated. The arrayed waveguide structure comprises Masterbond UV-curable epoxy UV15 optimised using ZEMAX optical design software to achieve high efficiency of heat capture through far-infrared light focussing and subsequent absorption of the radiation on a centralised fluid...
We present the concept of a refractive index sensor based on integration of a three dimensional photonic crystal with a microchannel by femtosecond laser fabrication. The sensor performance was characterized by FTIR spectroscopy.
In this paper, fluid flow generated by laser irradiation in a high-frequency electric field was investigated with a view to using it as the driving force for a micropump. We discovered an optoelectrostatic phenomenon known as optoelectrostatic microvortex (OEMV) ten years ago. The OEMV is generated around the focal point of a laser beam located in the center of an intense high-frequency electric field...
