A direct and continuous spectrophotometric method was developed for determining arginine kinase (phosphoarginine synthesis) activity. Protons are produced during the phosphoarginine synthesis course, so adding the complex acid-base indicator to this solution and monitoring the decrease of absorbance of the

A simple general synthetic concept to build dendritic core-shell architectures with pH-labile linkers based on hyperbranched PEI cores and biocompatible PEG shells is presented. Using these dendritic core-shell architectures as nanocarriers, the encapsulation and transport of polar dyes of different
