A facile strategy for the synthesis of a NaREF4-gold nanocomposite as a dual-modal bioimaging agent
نویسندگان
چکیده
In this article, a facile strategy is developed to synthesize a nanocomposite containing both a rare earth doped upconversion nanoparticle (RE-UCNP) and gold nanoparticles (GNPs). Such a nanocomposite can serve as a dual-modal imaging agent for upconversion luminescence (UCL) imaging and photoacoustic tomography (PAT). High spatial resolution, 3-dimensional imaging of blood vessels could be achieved with the RE-UCNP/GNPs@SiO2 nanocomposite by PAT, while UCL imaging offers a high-speed, lowinterference and 2-dimensional imaging mode.

متن کاملFacile Synthesis and Potential Bioimaging Applications of Hybrid Upconverting and Plasmonic NaGdF4: Yb3+, Er3+/Silica/Gold Nanoparticles
We present a simple method for preparing water dispersible NaGdF4: Yb3+, Er3+/silica/gold nanoparticles. The emission intensity and color of the upconverting cores are modulated by the plasmonic absorbance and field enhancement from the gold nanoparticles. The applicability of hybrid NPs for multi-modal bioimaging probes is illustrated by in vitro confocal microscopy of living cancer cells.
