Ratiometric fluorescence detection of Hg2+ based on gold nanocluster/carbon quantum dots nanohybrids

“…1,2 Mercury can enter the human body via the food chain, the respiratory system, or skin contact, and causes substantial harm to human health; 3,4 even modest quantities of mercury ions ($5 ppb) have been found to damage the organs. 5 Various analytical methods, including atomic absorption spectrometry (AAS), 6 electrochemical methods, 7 and UV-vis spectroscopy, 8 among others, have been used to detect mercuric ions (Hg 2+ ) in environmental and biological samples. However, these techniques have substantial downsides and limitations, such as being costly, ineffective, time consuming and limited in scope.…”

3D Biomass‐Derived Carbon Materials for Electrochemical Biosensors

“…In recent years, as a member of the carbon family, BC, especially 3D-BC structures, has received increasing attention from researchers. Compared to other carbon-based electrode modification materials such as graphene and carbon nanotubes, BC is designed and obtained from natural biomaterials, which reduces the cost of sensor preparation and creates great economic [27,28,[37][38][39][40][41][42] The performance improvement diagrams of BC-based materials in b) DA, [16,24,[43][44][45][46][47][48][49] c) Pt 2+ , [38,41,[50][51][52][53][54][55][56] and d) H 2 O 2 [23][24][25]28,[57][58][59][60][61] in recent years. e) Comparison of the sensing performance of BC-based modified materials for DA, Pt 2+ , and AP.…”

“…We compiled a timeline of the development of BC electrode modification materials, which provides a good overview of the progress reported each year (Figure 1a). [27,28,[37][38][39][40][41][42] We also summarize the performance improvement maps of BC-based materials in recent years for health (Figure 1b), [16,24,[43][44][45][46][47][48][49] environment (Figure 1c), [38,41,[50][51][52][53][54][55][56] and biomolecules (Figure 1d). [23][24][25]28,[57][58][59][60][61] BC has shown continuous research hotspots in life and health fields with breakthroughs in its sensing performance.…”
