Quantum Dots Microspheres


By embedding the quantum dots in the inorganic material, Mesolight microspheres can make the quantum dots less susceptible to the influence of the external environment, and significantly improve the stability and detection sensitivity. With hydrophilic coated of the surface, Mesolight microspheres is an excellent material for high-sensitivity biological detection, which has good biocompatibility and low non-specific adsorption.
