Peptide−Nanowire Hybrid Materials for Selective Sensing of Small Molecules

Selective functionalization: Shields for small molecules.

P rotecting groups have a long history in synthetic chemistry 1. A protecting group is covalently attached to one functional group to block its reactivity while a second functional group undergoes a chemical transformation, after which the protecting group is then removed (Fig. 1a). The use of protecting groups requires both protection and deprotection steps, so efficiency considerations dictat...

Graphene Hybrid Materials in Gas Sensing Applications †

Graphene, a two dimensional structure of carbon atoms, has been widely used as a material for gas sensing applications because of its large surface area, excellent conductivity, and ease of functionalization. This article reviews the most recent advances in graphene hybrid materials developed for gas sensing applications. In this review, synthetic approaches to fabricate graphene sensors, the n...

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Electrophoretic exclusion for the selective transport of small molecules.

A novel method capable of differentiating and concentrating small molecules in bulk solution termed "electrophoretic exclusion" is described and experimentally investigated. In this technique, the hydrodynamic flow of the system is countered by the electrophoretic velocity to prevent a species from entering into the channel. The separation can be controlled by changing the flow rate or applied ...

Conducting Polymers for Ammonia Sensing: Electrodeposition, Hybrid Materials and Heterojunctions

Polyaniline (PANI) with electrodonating and electrowithdrawing substituents were electrodeposited and studied as sensing materials in resistors and heterojunctions. Whereas the dimethoxyaniline leads to a highly conductive material, the tetrafluoroaniline leads to a poor conducting polymer. However, this latter was used in heterojunctions, associated with a highly conductive material, the lutet...
