چکیده
We report on the fabrication of micropatterned polymer surfaces that allow the reversible inversion of surface topography, charge, and wettability. Micropatterned surfaces were prepared by grafting two oppositely charged polyelectrolytes (poly(acrylic acid) and poly(2-vinylpyridine)) using a combination of photolithography, "lift off", and "grafting to" techniques. The switchable surfaces are of interest in microprinting and for the design of microfluidic devices and programmed protein adsorption.

A switchable Fresnel zone plate lens is demonstrated using a polymer-stabilized liquid crystal. The fabrication process is relatively simple and the device can be operated below 10 volts with fast response time. Such a device works well for a linearly polarized light.
متن کاملMaskless liquid-crystal-display projection photolithography for improved design flexibility of cellular micropatterns.
We previously developed an all-in-one photopolymerization device by modifying a commercially available liquid crystal display projector (LCDP) for the preparation of micropatterned surfaces and microfluidic channels without the need for expensive photomasks. In the present study, we demonstrate a simple and reliable method for rapid prototyping of cell micropatterning with high resolution using...
متن کاملElectrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals using a Michelson interferometer
Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
متن کاملFabrication of polymer-SiO2 nanocomposite optical fibers with a new method
At first step polymer optical fibers (POFs) are used in short distance for optical data transmissions. At second step SiO2 nanoparticles were prepared by sonochemical-assisted method. Silica nanoparticles were added to polymer matrix to prepare polymer based nanocomposites. Most of the POF applications are in the medical and electrical devices. There are several methods for fabrication of POFs,...
متن کاملFabrication of an Electrochemical Sensor Based on a New Nano-ion Imprinted Polymer for Highly Selective and Sensitive Determination of Molybdate
In this work a new chemically modified carbon paste electrode was constructed for accurate, simple, sensitive and selective determination of molybdenum (VI) ions. The results of modified electrode by an ion imprinted polymer were compared with those obtained with carbon paste electrode. The results showed the stripping peak currents had a dramatic increase at the modified electrode. Under the o...
