General description

Reactive group: Octadecylamine.

Application

Highly purified CdSe/ZnS quantum dots with an octadecylamine surface contain extremely low free organic ligands and impurities. They are well suited for display, solid state lighting and solar cell applications. They can be used as an electroluminescence emitter in quantum dot based LEDs or embedded in a polymer matrix as the backlight of an LCD display. CdSe/ZnS quantum dots in solid form can be dispersed in most non-polar organic solvents such as toluene, chloroform, and hexane.

Recent Advances in the Use of Cadmiumfree Quantum Dots for Bioimaging

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
