Upconverting Nanoparticles:
Upconverting nanoparticles are nanoparticles that can convert low-energy near-infrared (NIR) light into higher-energy visible or ultraviolet (UV) light through a process known as upconversion. This is typically achieved using rare-earth ions such as Ytterbium (Yb3+), Erbium (Er3+), or Thulium (Tm3+) doped in a host lattice.
Polyethylene glycol (PEG) carboxyl coated upconverting nanoparticles are a type of nanomaterial with unique optical properties and surface modifications that make them suitable for various biomedical applications. The carboxyl groups on PEG can be used for further functionalization. They provide active sites for covalent attachment of biomolecules such as antibodies, peptides, or drugs, facilitating targeted delivery and specific interactions with biological targets.
The unique optical properties of our products are highly dependent on their material composition. They typically consist of a host matrix, activators, and sensitizers. The activator ions mainly provide luminescent centers, while the sensitizer ions absorb near-infrared light and transfer the absorbed energy to the activator ions, facilitating light emission. The matrix provides a crystalline host lattice structure for activating ions and sensitizing ions to the correct place, giving it the proper light conditions.
