Upconverting Nanoparticles:
Upconverting nanoparticles are a class of nanomaterials that can convert lower-energy (longer wavelength) photons, typically in the infrared (IR) or near-infrared (NIR) region, into higher-energy (shorter wavelength) photons in the visible or ultraviolet region. They are typically composed of a host inorganic crystal lattice in which the dopants can reside.
Mesoporous silica coated upconverting nanoparticles are promising nanomaterials that combine the unique properties of upconverting nanoparticles with the versatile surface chemistry and porosity of mesoporous silica to create a multifunctional nanoplatform. The mesoporous structure provides a high surface area that can be easily functionalized with various chemical groups, enhancing the versatility of the nanoparticles. Additionally, the pores can be loaded with drugs or other molecules for targeted delivery and controlled release applications.
Our products offer unique optical properties, enhanced stability and multifunctional capabilities that open up possibilities for a variety of advanced applications, especially biomedical applications.
