Abstract

Abstract: Invited for the cover of this issue are Anil Chandra, Loretta L. del Mercato and co‐workers at the Institute of Nanotechnology of National Research Council and the University of Salento. The image depicts how negatively charged pH‐sensitive pyranine (HPTS) molecules were successfully immobilized on silica microparticles (SMPs) without compromising the molecules′ pH sensitivity. These resulting sensors can be used to measure pH in vitro and in vivo due to the cytocompatibility of HPTS molecules and SMPs. Read the full text of the article at 10.1002/chem.202101568 . Abstract : "In this work, we successfully embedded HPTS molecules in silica microparticles but still retained their pH sensitivity. The synthesized pH‐sensitive microparticles were stable and showed a remarkable sensitivity to pH change."
