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

Abstract

Cu2+ detection was performed by taking advantage of the fluorescence quenching ability of graphdiyne and the high specificity of click chemistry.

Review of Graphdiyne-Based Nanostructures and Their Applications

“…Moreover, Guo et al 157 also achieved excellent results in the detection of Cd 2+ and Pb 2+ by using N-GDY. Ge et al 158 developed a Cu 2+ detection system based on GDY. The high specificity of the copper-ion-catalyzed click reaction using the sensor has excellent selectivity against the interference of other metal ions (Figure 20d).…”

Current Advances in the Synthesis, Properties, and Biomedical Applications of Two-Dimensional Graphdiyne: A Review

“…Meanwhile, GDY has abundant chemical bonds, highly π-conjugated systems, 36 an ordered arrangement of natural gas pores, 37 high carrier mobility, 38 and high fluorescence quenching efficiency. 39 Over the past decade, GDY has achieved success in the disciplines of energy preservation, catalysis, gas separation, and water purification. Furthermore, due to its surface adsorption and conjugated structure, excellent semiconductor and photoelectric properties, good stability, and excellent biocompatibility, 40 GDY has been extensively studied in bioapplications, such as drug transport, 41 sensing, 42−44 antibacterial processes, cancer therapy, optoelectronic synapses, and so on.…”

“…[7][8][9] This can pose serious health risks like anaemia, interstitial nephritis, oxidative damage, hypertension, cardiovascular disease, severe neurological disease, etc. 10,11 Therefore, the detection of these metal ions above the threshold limit needs immediate attention to address environmental pollution and minimize impacts on biological systems. 12,13 This leads to the importance of metal ion sensors based on organic frameworks for selective recognition.…”
