A nano-molar fluorescent turn-on probe for copper(II) detection in living cells

Graphdiyne nanosheets as a platform for accurate copper(ii) ion detection via click chemistry and fluorescence resonance energy transfer

“…S3B, † the viability of all selected cells was higher than 82% after incubation with high concentration (100 μg mL −1 ) of GDY NSs for 24 h, indicating the low toxicity and good biocompatibility of GDY NSs. 28,29 Similar results were obtained by using AO/PI to stain the living and dead cells (Fig. S4 † ).…”

Methods for biosensing and imaging

“…Molecular probes for metal ions detection, including Cu 2+ and Ni 2+ were developed and included in this special issue. A fluorescent turn on probe (PHC) was developed by Wei et al for Cu 2+ detection with high selectivity and sensitivity [7]. Sensing and imaging of Cu As a class of new-emerged nanomaterials, carbon dots (CDs), have gained significant attention for biosensing and imaging due to their good water solubility, strong fluorescence, excellent biocompatibility, and facile method of surface modification [14,15].…”

Recent endeavours in the development of organo chromo-fluorogenic probes towards the targeted detection of the toxic industrial pollutants Cu2+ and CN−: recognition to implementation in sensory device

“…Wu et al 75 reported a Cu 2+ -selective fluorescent ''turn-on'' chemosensor, probe 43, formed via the combination of phenyl hydrazine and coumarin-carbaldehyde. Due to CQN isomerization, it showed very weak fluorescence.…”
