By a News Reporter-Staff News Editor at Cancer Weekly -- Investigators discuss new findings in Quantum Dots. According to news originating from Linyi, People's Republic of China, by NewsRx correspondents, research stated, "A new photoelectrochemical (PEC) biosensor was developed using low-toxic Ag2S QDs as photoelectrochemically active species. Energy levels of Ag2S and Ag2Se QD were compared to explain their differences in the PEC performance."
Our news journalists obtained a quote from the research from Linyi University, "The preparation condition of Ag2S QD was optimized and its structure characterization was measured. Then the developed photoelectric active interface was used to detect glucose and MCF-7 cancer cell and showed the good sensitivity and specificity. Under optimal condition, detection limits of 3.2 x 10(-5) M for glucose and 98 cells/mL for MCF-7 cell were achieved."
According to the news editors, the research concluded: "Thus, the prepared Ag2S QD could serve as an excellent and promising photoelectric active material in the PEC biosensor."
