Back Cover: Our manuscript deals with highly efficient detection of cysteine using a complex of water-soluble hyperbranched conjugated polymer and cobalt ion. Upon exposure to cysteine, a more favorable cysteine–cobalt ion complex is formed which screens the incoming energy to excite the polymer, resulting in a quenching effect. The image illustrates the screening of blue excitation energy – the energy cannot reach the polymer. The Robot Taekwon V reflects the incoming excitation irradiation to protect the earth from a beam attack. Further details can be found in the article by D. Kim, G. Jang, J. Kim, S. Seo , W. H. Park, and T. S. Lee* on page 1510.
