Nitrogen-doped carbon nanoparticle modulated turn-on fluorescent probes for histidine detection and its imaging in living cells

Nitrogen-doped carbon nanoparticle modulated turn-on fluorescent probes with excellent biocompatibility for rapid and selective detection of histidine were developed, and were applied for a histidine imaging assay in living cells, which presented great potential in the bio-labeling assay and clinical diagnostic applications.
