Environmental suspects nailed

Thai researchers have developed an electrochemical method using redox catalysts for improved detection of organohalides, linked with ozone depletion and climate change. Mithran Somasundrum and co-workers utilized a better catalyst immobilized within a liquid crystal film. The redox catalyst reacts with an analyte and regenerates at an electrode, the resulting current being used to measure the analyte concentration. Future work will focus on portable hand-held sensors for on-site detection of suspected environmental contamination.

Bouncing water balls

Recent advances in the field of water repellency are discussed by Mathilde Callies and David Quéré who are based at CNRS in France. Superhydrophobicity is the unusual property of some materials to repel water, where drops of water barely stick to the surface and bounce back upon impact. This property is shown to be related to the presence of microtextures at the surface. The design of the solid surface and how the water contacts it is discussed.   

Inhibition activities

Peter Wipf and Robert Halter from the University of Pittsburgh, US, describe recent work on the synthesis, reactivity and biology of wortmannin - a potent enzyme inhibitor whose chemistry and biology has challenged scientists since it was first isolated in 1957. New potential biomedical applications of this steroid-like molecule continue to be found.   

Responsive brushes

Bacteria and proteins have been attached to stimuli-responsive polymer brushes. Poly(N-isopropylacrylamide) brushes grown on micropatterned gold surfaces by atom transfer radical polymerisation show reversible physicochemical changes around the lower critical solution temperature. The associated hydrophilic-hydrophobic switch of the brushes allows the variable attachment of bacteria and proteins to distinct areas using temperature control. This development could lead to surface arrays that can be tuned to adsorb or reject specific cell types.
