PEG Coated Upconverting Nanoparticles

Upconverting Nanoparticles:
Upconverting nanoparticles are innovative nanomaterials with the ability to convert low-energy near-infrared photons into higher-energy visible or ultraviolet photons. Their unique optical properties, including deep tissue penetration, low background noise, and high photostability, make them highly suitable for a wide range of applications in bioimaging, photodynamic therapy, sensing, and drug delivery.
Upconverting nanoparticles are commonly doped with lanthanide ions, such as erbium (Er³⁺), ytterbium (Yb³⁺), and thulium (Tm³⁺). Yb³⁺ ions often serve as sensitizers, absorbing infrared light and transferring energy to activator ions like Er³⁺ or Tm³⁺, which then emit light at shorter wavelengths. The energy transfer between sensitizer and activator ions is crucial for the upconversion process.
