In situ encapsulation of SQDs by zinc ion-induced ZIF-8 growth strategy for fluorescent and colorimetric dual-signal detection of alkaline phosphatase

ALP-assisted chemical redox cycling signal amplification for ultrasensitive fluorescence detection of DNA methylation

“…The sensitivity is comparable to or even better than many reported works (shown in Table S2†). 33–38 The high sensitivity is attributed to the usage of ALP-assisted chemical redox cycling dual signal amplification, demonstrating its potential applications in fluorescence sensing. These results further demonstrate the feasibility of the proposed ALP-assisted redox cycling signal amplification strategy.…”

Fabrication of highly luminescent and thermally stable composites of sulfur nanodots through surface modification and assembly

“…This is caused by a significant decrease in the PL QY after processing the S-dots in colloidal solution to the solid state, together with the relatively low melting point of sulfur-based materials. 28 Some groups engaged in promoting the solid photophysical properties of S-dots by modulating their surface states through producing their composite materials with BaSO 4 , 29 metal–organic frameworks (MOFs) 30–32 and polymers. 33,34 An improved PL QY was achieved on these composite materials.…”

Simultaneous Detection and Adsorptive Removal of Cr(VI) Ions by Fluorescent Sulfur Quantum Dots Embedded in Chitosan Hydrogels

“…Tan et al also found that SQDs treated by hydrogen peroxide could be utilized as a fluorescent probe for sensing Cr­(VI) ions . However, SQDs generally exhibit poor photostability and their surfaces are prone to photooxidization, leading to significant fluorescence attenuation in aqueous solution. − As such, the practical sensing applications of SQDs are severely limited.…”
