Lanthanide‐doped rare earth nanoparticles for near‐infrared‐II imaging and cancer therapy

open access: yesBMEMat, 2023
The optical nanoprobes with emissions in the second near‐infrared window (NIR‐II, 1000–1700 nm) show low tissue autofluorescence and photon scattering; therefore, they provide high spatial resolution and acceptable tissue penetration depth.
