Rapidly responding in situ analysis methods, such as mid-infrared optochemical sensors utilizing evanescent field absorption techniques, may inherently provide qualitative and quantitative information on multiple volatile organic contaminants in water. In their Communication on page 2265 ff., B. Mizaikoff et al. describe a planar infrared attenuated total reflection (IR-ATR) fiberoptic sensor that was coated with an ethylene/propylene copolymer. Such a system may be used for continuous monitoring of the water quality.

High-Throughput Screen

Graphene oxide was used as the substrate for a screen for inhibitors of DNA helicases by D.-H. Min et al. in their Communication on page 2340 ff. Several inhibitors of disease-related helicase targets were identified using this method.
