UV-induced fluorescence recovery and solubility modulation of photocaged conjugated oligomers: A series of conjugated oligomers that show both increased fluorescence efficiency and pH-dependant solubility upon UV irradiation have been designed by a team at Tufts University, USA. The team behind the research say this approach is effective at tuning the properties of conjugated organics with light after traditional synthetic operations, and has potential for use in photoactivatable fluorophores or solution-processable multilayer devices.

Direct write tethered protein arrays: Protein arrays can be written directly onto a protein resistant surface. This approach eliminates the need for additional back-filling steps. The team behind the research say their method can tolerate a broad range of process conditions which allows the retention of proteins’ biological functionality. (J. Mater.

Atomic layer deposition of metal fluorides through oxide chemistry: This hot article describes the deposition of metal fluoride thin films by an atomic layer deposition process using ozone based chemistry. The team say that using hexafluoroacetylacetonate as a fluorine source increased the purity of the films by reducing the oxygen content. (J. Mater. Chem., 2011, 21, 14461-14465)
