Single dot luminescence characteristics of CdSe/ZnS core-shell structured quantum dots with different ligands

Yu H., Song N.W., Moon D.W., Shin S.K., Korea Research Institute of Standards and Science, KR

Chemical derivatizations with different ligands were perfomed on CdSe/ZnS core-shell quantum dots (QDs). The role of ligands serves to increase water solubility and bio-compatibility of QDs for in-vivo biomedical fluorescence imaging. These QDs were synthesized [...]

Confocal Raman AFM, a powerful tool for the nondestructive characterization of heterogeneous materials

Schmidt U., Vargas F., Kress M., Dieing T., Weishaupt K., Hollricher O., WITec GmbH, DE

The Confocal Raman-AFM is a breakthrough in microscopy. It combines three measuring techniques in one instrument: a high resolution confocal optical microscope, an extremely sensitive Raman spectroscopy system, and an Atomic Force Microscope (AFM). Using [...]

Control of Micro-Fluidic Flow using 3D Features

Bullock L.E., Robinson A.E., University of Massachusetts Dartmouth, US

Lab-on-a-Chip sensors require precise control and mixing of samples, reagents and buffers. This paper will present new techniques for using Excimer Laser, micro-machined, three-dimensional (3D) channel and well features to pump and control fluids in [...]
