Abstract Fluorescence imaging in the second near-infrared window (NIR-II) allows visualization of deep anatomical features with an unprecedented degree clarity. NIR-II fluorophores draw from a broad spectrum materials spanning semiconducting nanomaterials to organic molecular dyes, yet unfortunately all water-soluble molecules >1,000 nm emission suffer low quantum yields that have limited temporal resolution and penetration depth. Here, we report tailoring supramolecular assemblies...

Trading up: A bioimaging system that is based on caged D-luciferin/upconversion nanoparticle conjugate has been developed. The nanoparticles upconvert near-infrared light into UV light, which triggers the photorelease of D-luciferin (see scheme) and leads to enhanced fluorescence bioluminescence signals in vitro vivo. use enables deep penetration tissue vivo with minimum cellular damage. Detailed facts importance specialist readers are published as "Supporting Information". Such documents...

The effect of nanoparticle size (30−120 nm) on magnetic resonance imaging (MRI) hepatic lesions in vivo has been systematically examined using polyvinylpyrrolidone (PVP)-coated iron oxide nanoparticles (PVP-IOs). Such biocompatible PVP-IOs with different sizes were synthesized by a simple one-pot pyrolysis method. These exhibited good crystallinity and high T2 relaxivities, the relaxivity increased nanoparticles. It was found that cellular uptake changed both surface physiochemical...
