PVP-coated ultrasmall Nd-doped Gd₂O₂S nanoparticles for multimodal imaging

Abstract

Rare-earth (RE) based inorganic nanoparticles (NPs) are emerging nanoprobes, have been widely explored. Single RENP as contrast agent for multimodal bioimaging is able to combine optical, ultrasonic, magnetic and electronic...

Multimodal optoacoustic imaging: methods and contrast materials

“…Rare-earth oxysulfide (Gd 2 O 2 S) NPs have shown excellent optical performance and low cytotoxicity. 126 Vanadium carbide (V 2 C) QDs modified with TAT peptides and packaged into engineered exosomes could realize nucleus targeting and further destroy tumor cells by low-temperature photothermal therapy. 142 Ultrasmall carbon dots without excess modification could further penetrate deeper into tumors for improved therapeutic outcomes.…”
