By a News Reporter-Staff News Editor at Clinical Trials Week -- Investigators publish new report on Immunology. According to news reporting out of Mexico City, Mexico, by NewsRx editors, research stated, "The paper presents a comparative study of the photoluminescence (PL) and Raman scattering spectra of the core-shell CdSe/ZnS quantum dots (QDs) in nonconjugated states and after the conjugation to anti-Interleukin 10 antibodies (anti-IL10). All optical measurements are performed on the dried droplets of the original solution of nonconjugated and bioconjugated QDs located on the Si substrate."
Our news journalists obtained a quote from the research from National Polytechnic Institute, "CdSe/ZnS QDs with emission at 605 and 655 nm have been used. PL spectra of nonconjugated QDs are characterized by one Gaussian shape PL band related to the exciton emission in the CdSe core. PL spectra of bioconjugated QDs have changed essentially: the core PL band shifts into the high energy spectral range ('blue' sift) and becomes asymmetric. Additionally two new PL bands appear. A set of physical reasons has been proposed for the 'blue' shift explanation for the core PL band in bioconjugated QDs. Then Raman scattering spectra have been studied with the aim to analyze the impact of elastic strains or the oxidation process at the QD bioconjugation. The variation of PL spectra versus excitation light intensities has been studied to analyze the exciton emission via excited states in QDs."
According to the news editors, the research concluded: "Finally the PL spectrum transformation for the core emission in bioconjugated QDs has been attributed to the electronic quantum confined effects stimulated by the electric charges of bioconjugated antibodies."
