New Quantum Dots Study Results Reported from Qingdao University of Science and Technology

June 3, 2014

By a News Reporter-Staff News Editor at Cancer Weekly -- Investigators publish new report on Quantum Dots. According to news reporting out of Qingdao, People's Republic of China, by NewsRx editors, research stated, "In this work, a novel polymeric quantum dot/aptamer superstructure with a highly intense fluorescence was fabricated by a molecular engineering strategy and successfully applied to fluorescence imaging of cancer cells."

Our news journalists obtained a quote from the research from the Qingdao University of Science and Technology, "The polymeric superstructure, which is composed of both multiple cell-based aptamers and a high ratio of quantum dot (QD)-labeled DNA, exploits the target recognition capability of the aptamer, an enhanced cell internalization through multivalent effects, and cellular disruption by the polymeric conjugate. Importantly, the polymeric superstructure exhibits an increasingly enhanced fluorescence with recording time and is thus suitable for long-term fluorescent cellular imaging."

According to the news editors, the research concluded: "The unique and excellent fluorescence property of the QD superstructure paves the way for developing polymeric QD superstructures that hold promise for applications such as in vivo imaging."
