The doping concentrations are optimized, leading to strong upconverted emissions at specific wavelengths. The size of UCNs can be customized based on the user’s need. The oleates have been removed from the nanoparticle surface through treatment with diluted hydrochloric acid, rendering UCNs dispersible directly in water and ethanol. The UCNs are of high quantum efficiency and very photostable. After proper surface modification and functionalization, the products can be used for fluorescence imaging, biodetection, photodynamic therapy and photoactivation of anti-cancer drugs and biomolecules.

Application

Upconverting nanoparticles have excellent photostability and have been widely used in biomedical applications, including in vitro bioimaging, in vivo bioimaging, bioassays, immunohistochemistry, microarray detection, photodynamic therapy, and photo-controlled drug activation.

Upconverting nanoparticles are able to convert near-infrared radiations with lower energy into visible radiations with higher energy via a nonlinear optical process. The doping concentrations and the size of upconverting nanoparticles can be customized based on your specific requirements.

Our upconverting nanoparticles can either be oil or water-dispersible. By precise surface modification, upconverting nanoparticles are available with coated, amine-functionalized and antibody conjugated forms. These photoluminescent nanoparticles can be used for bio-imaging, molecular recognition, and photodynamic therapy.
