Urea-Based Imprinted Polymer Hosts with Switchable Anion Preference

A Zipper-Like On/Off-Switchable Molecularly Imprinted Polymer

Thiosquaramides: pH switchable anion transporters.

The transport of anions across cellular membranes is an important biological function governed by specialised proteins. In recent years, many small molecules have emerged that mimick the anion transport behaviour of these proteins, but only a few of these synthetic molecules also display the gating/switching behaviour seen in biological systems. A small series of thiosquaramides was synthesised...

Electrically 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...

Urea Biosensor based on Conducting Polymer Transducers

Urea is one of the final products of protein metabolism. In clinical analysis and dairy industry urea is a very significant parameter as excess in blood serum from its permissible range causes dysfunction of the kidney. Hence, its analysis is significant and is carried out frequently in various laboratories [1, 2]. Urea is an omnipresent compound present in blood and various organic fluids. It ...

Molecularly Imprinted Polymer Sensors

An interdigitated electrode sensor was designed and microfabricated for measuring the 11 changes in the capacitance of three phosphate selective molecularly imprinted polymer (MIP) 12 formulations, in order to provide hydroponics users with a portable nutrient sensing tool. The 13 MIPs investigated were synthesised using different combinations of the functional monomers 14 methacrylic acid (MAA...
