A specific fluorescence probe for chromium (VI) anions and its application

Solid-Phase Pyrolysis Synthesis of Highly Fluorescent Nitrogen/Sulfur Codoped Graphene Quantum Dots for Selective and Sensitive Diversity Detection of Cr(VI)

“…To date, numerous fluorescence probes such as organic dyes, 8 carbon dots, 9 semiconductor nanocrystals, nanoparticles (NPs), 10 metal−organic frameworks, 11 and metal nanoclusters 12 have been employed for Cr(VI) detection, among which carbon dots have gained increasing attention due to their high biocompatibility, good solubility in water, excellent chemical stability, and high and tunable optical properties. 13 As a newly developed member of carbon dots, graphene quantum dots (GQDs) have gained significant research interest in various fields ranging from energy storage, 14 catalysis, 15 to biological and chemical sensing 16 due to their extraordinary thermal, optical, and electronic properties.…”

A polystyrene-based ESIPT fluorescent polymeric probe for highly sensitive detection of chromium(vi) ions and protein staining

“… 7 As a result, the World Health Organization (WHO) has suggested the maximum allowable concentration for Cr( vi ) in the ground and drinking water should not exceed 50 μg L −1 , which were set by many nations. 8 Consequently, to develop a sensitive, simple and rapid analytical method is highly desirable for monitoring Cr( vi ) in water, environmental, food and biological samples.…”

A new aggregation induced emission enhancement (AIEE) dye which self-assembles to panchromatic fluorescent flowers and has application in sensing dichromate ions

“…2,3 In 2001, Tang et al for the very first time reported 1-methyl-1,2,3,4,5-pentaphenylsilole AIE molecules. 3 This was groundbreaking research that led to the design of different AIE dyes, with a wide range of applications in various fields such as tissue engineering, 4 cell tracking, 5 OLEDs, 6 bioprobes, 7 sensing, [8][9][10][11][12] etc. The most recognized and prevalent scaffold for the design of AIE dyes is tetraphenylethylene (TPE) 13 and hexaphenylsilol (HPS).…”
