Front Cover: A “Signal On” Photoelectrochemical Biosensor Based on... Bi nanocrystal and N,O‐codoped carbon (NOC) core–shell (Bi@NOC) nanohybrids have been synthesized that exhibit semiconducting features with a bandgap of 1.14 eV. These nanohybrids show good biocompatibility and their surfaces bear carboxylic groups, which facilitate further assembly of amino‐modified primer DNA. A “signal on” photoelectrochemical aptasensor has been fabricated that can detect the telomerase activity from 5.0×102 to 1.0×106 HeLa cells with a low detection limit of 60 cells. It shows a wide linear response range, high sensitivity and good reproducibility.
