Molecular Imprinted Polymers: A Review

Design of molecularly imprinted polymers for diphenylamine sensing.

A series of the polymers imprinted with diphenylamine (DPA) and respective non imprinted polymers were synthesized using precipitation polymerization. Synthesized polymers were characterized by Fourier Transform Infra-Red spectroscopy with Total Attenuated Reflectance (FTIR-ATR), Scanning Electron Microscopy (SEM) and equilibrium batch re-binding experiments. Influence of the synthesis conditio...

Droplet-based interfacial capacitive sensing.

This paper presented a novel droplet-based pressure sensor using elastic and capacitive electrode-electrolyte interfaces to achieve ultrahigh mechanical-to-electrical sensitivity (1.58 μF kPa(-1)) and resolution (1.8 Pa) with a simple device architecture. The miniature transparent droplet sensors, fabricated by one-step laser micromachining, consisted of two flexible polymer membranes with cond...

Bisphenol A analog-imprinted polymers prepared by an immobilized template on a modified silica microsphere matrix.

Bisphenol A (BPA)-recognizing imprinted polymers were synthesized using a template immobilized on silica where the template was grafted to aminopropyl silica. The silica-template conjugate was co-polymerized with a cross-linker (ethylene glycol dimethacrylate) and a functional monomer (4-vinylpyridine or methacrylic acid). The synthesized silica-polymer composites were treated with an aqueous N...

Molecularly imprinted polymers in chemical and biological sensing.

In recent years the field of sensor technology has developed enormously, and biosensors in particular have attracted increased interest. This can be attributed to an extended demand for sensor devices for monitoring and control in biotechnology, the food industry, in the biomedical field, and in environmental analysis. Being highly sensitive and specific, biosensors provide an attractive altern...
