The present study processed the absorption spectrum of CdSe nanocrystals (Ncs) which was modified by mercaptoacetic acid (MA). Based on this, the LEDs whose emission peak is near the absorption peak of the NCs were selected to form a LED array. The leukemia cell line HL60 was cultured in two 96-well plates and incubated with different concentrations of MA-Coated CdSe NCs. One of the 96-well microplates...
Nanoparticles are increasingly being recognised for their potential utility in biomedicine. Here, the authors present a low-temperature, solvothermal method to synthesise zinc oxide (ZnO) nanorods using ZnO nanoparticles as precursors, with the addition of low-density polyethylenimine (PEI). This surfactant, which is in regular use in biology, has a double advantage: (i) it catalyses the synthesis...
Before using semiconductor quantum dots (QDs) in biomedical applications in vivo, it's important to know about their interaction with biological surroundings, stability in living organisms, intracellular distribution and cytotoxicity. We have investigated CdTe-MPA and (CdSe)ZnS-MUA QDs in the osteosarcoma U2-OS cell culture. The changes in photoluminescence spectra of QDs, the localization of QDs...
