Upconverting Nanoparticles:
Upconverting nanoparticles are nanoscale particles that exhibit photon upconversion. At the beginning of this century, with the advancement of nanotechnology in the preparation of small, high-quality and high-brightness nanoparticles, upconverting nanoparticles were investigated for biological applications. Their key advantage is their ability to overcome the limitations of conventional organic dyes and fluorescent probes, such as photobleaching, low photostability and low tissue penetration. Upconverting nanoparticles also have tunable emission spectra, making them attractive for various biomedical applications.

Our Products
Ligand-free upconverting nanoparticles are nanomaterials capable of converting low-energy photons into high-energy photons through an upconversion process. Unlike traditional upconverting nanoparticles that are coated with ligands for stabilization, ligand-free nanoparticles do not have any surface ligands attached to them. This lack of ligands can lead to several advantages, including improved stability, enhanced optical properties, and reduced potential for toxicity in biological applications.
These nanoparticles can be excited by near-infrared light and emit light in the visible or ultraviolet range, making them useful for a variety of applications such as bioimaging and photodynamic therapy.
