We have some very colourful images this July on the covers of Analytical Methods. The front cover image comes from Japan, where Takashi Jin from Riken, and colleagues have been developing quantum dots to be used as fluorescent probes for measuring the cytoplasmic viscosity of a single living cell.

Still in Asia for our inside front cover, the image comes from Xiaocheng Weng and Xiang Zhou from Wuhan University, who together with colleagues have been developing a sensor to detect silver and cysteine with the use of graphene oxide and G-quadruplex DNA.

We also have a back cover this month! It features the work of Sabato D’Auria and colleagues at the Institute of Protein Biochemistry of the Italian National Research Council, and Selex-SI, Italy. Ephedrine is a precursor for the illegal preparation of amphetamines, therefore a quick and reliable detection system for its presence is essential.
