The PDMA-modified UCNPs/Poly(N,N-dimethylacrylamide)-coated upconverting NaYF4:Yb,Er@NaYF4:Nd core–shell nanoparticles,808 nm excitation,Water Soluble can be used for in vivo and ex vivo imaging due to their low toxicity and high signal intensity.The nanoparticles can be utilized in photodynamic therapy (PDT) or photothermal therapy (PTT) for cancer treatment, where the upconversion emission can activate photosensitizers or induce thermal effects.The functionalization potential of PDMA allows for targeted drug delivery applications, where drugs can be conjugated to the PDMA layer for controlled release.
