AgInZnS quantum dots as anodic emitters with strong and stable electrochemiluminescence for biosensing application

Potential-selective electrochemiluminescence of AgInS2/ZnS nanocrystals and its immunoassay application

“…Benefitting from the dual-stabilizer of TSC and TGA as well as the optimized electrode, the ECL potential of the proposed AIS/ZnS NCs/N 2 H 4 in this case is lower than the previously reported AIS/ZnS NCs/TEA 39 and AIS/ZnS NCs/TPrA. 34 The charge transfer for electrochemically injecting holes and electrons onto AIS/ZnS as well as the annihilation of these holes This journal is © The Royal Society of Chemistry 2024 and electrons within AIS/ZnS NCs for ECL can be described as follows: 33 According to Fig.…”

Artificial Neurons Using Ag−In−Zn−S/Sericin Peptide‐Based Threshold Switching Memristors for Spiking Neural Networks

“…[ 16 ] Three characteristic diffraction peaks of QDs located at 27.22°, 45.36°, and 53.54° have been observed in Xray diffraction (XRD) pattern in Figure S2a (Supporting Information), matching well with three phases of the hexagonal structure, that is, (002), (110), and (112) phases respectively, which demonstrates the successful synthesis of AIZS QDs. [ 17 ] In addition, the transmission electron microscopy (TEM) image shows that the average size of AIZS QDs is ≈5 nm. The particle size distribution of sericin is distinctly illustrated in Figure a, with the percentage peak (depicted by the black curve) correlating to a size of ≈60 d nm.…”

Electrochemiluminescence of Semiconductor Quantum Dots and Its Biosensing Applications: A Comprehensive Review

“…Based on the dual quenching effects, a sensitive ECL biosensing of microRNA is achieved with a wide linear range and acceptable selectivity. In addition, various signal amplification strategies have been widely explored to further improve the sensitivity of nucleic acid analysis, such as target-induced recycling amplification, cascade amplification strategies and strand displacement reactions [110][111][112][113][114][115][116]. For example, Yuan et al constructed a novel ECL biosensor to achieve the ultrasensitive detection of microRNA by combining target recycling amplification and double-output conversion strategies [110].…”
