Upconverting Nanoparticles:
Upconverting nanoparticles are nanoparticles that can absorb two or more low-energy (near-infrared) photons and emit a higher-energy photon through a process known as upconversion. They are useful in bioimaging, sensing and other applications requiring deep tissue penetration and minimal background fluorescence.
Polyethylene glycol (PEG) amino coated upconverting nanoparticles are advanced nanomaterials with unique optical properties and biocompatibility. These properties make them ideally suited for a variety of biomedical applications. The PEG coating ensures stability and compatibility in biological environments, while the amino groups provide reactive sites for further conjugation with targeting ligands, drugs, or other biomolecules.
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.
