Selective detection of aspartic acid in human serum by a fluorescent probe based on CuInS2@ZnS quantum dots

Advancements in semiconductor quantum dots: expanding frontiers in optoelectronics, analytical sensing, biomedicine, and catalysis

“…This probe's lower limit of detection was determined to be 78 nM. 211 The application of CQDs as a sensor is not limited to amino acids but also extends to peptides like GSH present in human serum. Yun Shu et al constructed a new fluorescent sensing platform that is intended for the quick and accurate measurement of glutathione (GSH).…”

Insight into the Synthetic Mechanism of Cadmium-Free Blue-Emissive Quantum Dots for Eco Light-Converting System

“…In this regard, CuInS 2 (CIS), a typical copper-based ternary composite, has attracted attention because its PLQY can be increased to as high as ∼0.8 with a ZnS shell overcoating onto its surface. The emission color of CIS QDs can be tuned from green to the near-infrared (NIR) spectral region by simply controlling the Cu/In molar ratio and size with lower toxicity than Cd-based QDs. − However, the absence of blue-region emission, which requires a much larger band gap, in CIS QDs has prompted further efforts to find blue-emissive probes suitable for optoelectronic applications. Meanwhile, as the Cd-free QD-based light-emitting diode (LED) systems − have been developed in these research fields, white-light-emitting diodes (LEDs) are considered a next-generation light source.…”

Differential detection of aspartic acid in MCF-7 breast cancer cells

“…Due to their simplicity, high selectivity, sensitivity, low cost, easy implementation, and real-time detection, it is always preferable to use chemosensors as an expedient tool in biological and clinical examination. [22][23][24][25][26][27][28][29] Herein, we report a pyridine-carbazole framework (PCF) to detect aspartic acid in live cell systems. The PCF probe has been characterized using UV-visible, fluorescence, 1 H NMR, 13 C NMR, and high-resolution mass spectrometry spectra, for C 20 H 18 N 3 with calc.…”
