By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Sulfur Amino Acids have been published. According to news reporting out of Wuhan, People's Republic of China, by NewsRx editors, research stated, "Using N-acetyl-L-cysteine (NAC) as a stabilizer, well water-dispersed, high-quality and stable CdHgSe quantum dots were facilely synthesized via a simple aqueous phase method. The as-prepared NAC capped CdHgSe quantum dots were thoroughly characterized by fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy."
Our news journalists obtained a quote from the research from the College of Chemistry and Materials Science, "A novel method for the selective determination of hemoglobin (Hb) was developed based on fluorescence quenching of the NAC capped CdHgSe quantum dots. A number of key factors including pH value of phosphate buffer solution, quantum dots concentration, the adding sequence of reagents and reaction time that influence the analytical performance of the NAC capped CdHgSe quantum dots in Hb determination were investigated. Under the optimal experimental conditions, the change of fluorescence intensity (AI) was linearly proportional to the concentration of Hb in the range of 4.0 x 10(-9)-4.4 x 10(-7) - mol L-1 with a detection limit of 2.0 x 10(-9) mol L-1."
According to the news editors, the research concluded: "The developed method has been successfully employed to determine Hb in human urine samples."
