摘要
An upconversion nanoparticle includes at least one host selected from LiYF4, NaY, NaYF4, NaGdF4, and CaF3, at least one sensitizer selected from Sm3+, Nd3+, Dy3+, Ho3+, and Yb3+ doped in the at least one host, and at least one activator selected from Er3+, Ho3+, Tm3+, and Eu3+ doped in the at least one host. The upconversion nanoparticle is designed using a calculation from first principles to absorb light in the near-infrared wavelength range whose stability is ensured. Further, a hyaluronic acid-upconversion nanoparticle conjugate, in which the upconversion nanoparticle as described above is bonded to hyaluronic acid, is provided to be used in various internal sites with a hyaluronic acid receptor, particularly enables targeting, and increases an internal retention period and biocompatibility thereof.
