“…Li et al [81] prepared a composite photocatalyst CDs/ Cs 4 PW 11 Fe(III) by modifying CDs on the surface of Cs Silver phosphate (Ag 3 PO 4 ) has been aroused much attention for its excellent activity in visible light-driven photocatalytic degradation of organic pollutants. [82] However, the negative charge generated on Ag 3 PO 4 is not sufficient to reduce O 2 to •O 2 − , which limits its application in the field of catalysis.…”

extensive research in the fields of drug delivery, chemical sensing, bioimaging, and specifically catalysis. [7][8][9] For instance, Liu's group has prepared CDs-confined CoP-CoO nanoheterostructure, Ru@CDs, RuM/CDs (M = Ni, Mn, Cu), and RuCo/ CDs catalysts with excellent catalytic performance, which can be widely used for electrolysis of hydrogen. [10][11][12][13] Catalysis, especially photocatalysis, is a topic that has received a lot of attention recently. Conventional photocatalysts include titanium dioxide, zinc oxide, and cadmium sulfide and many other oxide sulfide semiconductors, but these catalysts are basically limited in their use by low light utilization and high lightinduced electron-hole complexation rates. [14,15] As functional nanomaterials with excellent optical and electronic properties such as efficient light harvesting, extraordinary UCPL, and excellent photoinduced electron transfer, CDs combined with photocatalysts can broaden the photoresponsive region and improve the separation ratio of photoinduced carriers. [16,17] CDs are therefore considered to be an effective component for the construction of high-performance photocatalysts, and this area has been extensively investigated by researchers. CDs/Bi 2 MoO 6 composite photocatalysts were prepared by Samanta et al. [18] CDs led to an increase in catalyst light absorption and carrier separation efficiency. Zha et al. [19] synthesized a photocatalyst CDs/BiOCl using Chlorella vulgaris as a carbon source for CDs (CBOC). The introduced CDs broadened the response range of the spectrum, promoted the separation of electron-hole pairs, and enhanced the photocatalytic efficiency.The photocatalytic mechanism of CDs can be the photoexcitation and charge separation of the core carbon. [20] In general, the photocatalytic process based on CDs is divided into the following three processes. First, the absorption of light leads to the generation of electron-hole pairs. Second, the separation and transfer of electron-hole pairs create prerequisites for the reaction. Finally, a redox reaction takes place on the photocatalytic surface. [21] The main factors limiting the photocatalytic process are light absorption and the rate of electron-hole pair complexation, and many approaches have been taken to alleviate these problems.In view of the excellent performance of CDs in photocatalysis, previous reviews have summarized the approaches to improve the photocatalytic efficiency of CDs and the applications of CDs-based photocatalytic materials. [22][23][24][25][26] However, this thesis provides a review of the recent literature in this With their unique optical and electronic properties, carbon dots (CDs) are showing great momentum in many fields such as biosensing, imaging, drug delivery, and photocatalysis. Due to their efficient light harvesting, extraordinary upconversion photoluminescence, and excellent photoinduced electron transfer capabilities, the combination of CDs with photocatalytic materials will promote light absorption resulting in increased generation...

“…Especially since the appearance of novel carbon materials, significant progress has been obtained in detective research on selectivity, sensitivity and on-site detection. Among them, carbon quantum dots (or carbon dots, CDs, CQDs), due to their solubility, biocompatibility and lower toxicity, have been thought more efficient functional materials in the construction of a biosensor, since it was recognized by Sun et al, at first [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. As semiconductor quantum dots, CDs are quasizero dimensional materials with spherical shape, and their size in three dimensions is less than 10 nm, which limited internal electrons to move in this space.…”

Depression has become the leading cause of disability worldwide and is a global health burden. Quantitative assessment of depression-related neurotransmitter concentrations in human fluids is highly desirable for diagnosis, monitoring disease, and therapeutic interventions of depression. In this review, we focused on the latest strategies of CD-based electrochemical biosensors for detecting a depression-related neurotransmitter. We began this review with an overview of the microstructure, optical properties and cytotoxicity of CDs. Next, we introduced the development of synthetic methods of CDs, including the “Top-down” route and “Bottom-up” route. Finally, we highlighted detecting an application of CD-based electrochemical sensors in a depression-related neurotransmitter. Moreover, challenges and future perspectives on the recent progress of CD-based electrochemical sensors in depression-related neurotransmitter detection were discussed.
