A photothermal pH-reporting nanoprobe was developed for intraoperative tumor detection by "turn-on" fluorescence of the probe inside viable tumor cells, photothermal tumor therapy, and in situ monitoring of tumor killing by non-fluorescence of the probe in damaged cells.
A novel type of bimodal imaging nanoprobe based on (19)F-based magnetic resonance imaging and near-infrared optical imaging has been synthesized and applied for the labeling and imaging of dendritic cells both in vitro and in vivo.
A novel dextran-based nanoprobe was synthesized and demonstrated the pH-activated near-infrared (NIR) fluorescence in the physiologically acidic aqueous solutions and acidic compartments in human glioblastoma cancer cells.
Hybrid nanoprobe specifically designed to use as a contrast agent targeting phagocytic cells in an animal model of ischemic stroke and imaging using MRI, intravital two-photon microscopy phase X-rays imaging.
A ratiometric, multifunctional nanoprobe was prepared consisting of a self-assembled polymeric micelle as the carrier, tetraphenylethene (TPE) as the donor, fluorescent boronate as the H2O2-responsive acceptor, and triphenylphosphonium as a mitochondria-targeted moiety. The assembled nanoparticles could detect both exogenous and endogenous mitochondrial H2O2 changes in living cells.
Surface-enhanced Raman scattering (SERS) optical nanoprobes offer a number of advantages for ultrasensitive analyte detection. These functionalized colloidal nanoparticles are a multifunctional assay component. providing a platform for conjugation to spectral tags, stabilizing polymers, and biorecognition elements such as aptamers or antibodies. We demonstrate the design and characterization of...
In order to delineate the location of the tumor both before and during operation, we developed targeted bi-functional polymeric micelles for magnetic resonance (MR) and fluorescence imaging in liver tumors. Hydrophobic superparamagnetic iron oxide nanoparticles (SPIONs) were loaded into the polymeric micelles through self-assembly of an amphiphilic block copolymer poly(ethylene glycol)-poly(ϵ-c...
The Nanoscopium 155 m-long beamline of Synchrotron Soleil is dedicated to scanning hard X-ray nanoprobe techniques. Nanoscopium aims to reach ≤100 nm resolution in the 5-20 keV energy range for routine user experiments. The beamline design tackles the tight stability requirements of such a scanning nanoprobe by creating an overfilled secondary source, implementing all horizontally reflecting ma...
Extracellular vesicles (EVs) can mediate intercellular communication by transferring cargo proteins and nucleic acids between cells. The pathophysiological roles and clinical value of EVs are under intense investigation, yet most studies are limited by technical challenges in the isolation of nanoscale EVs (nEVs). Here, we report a lipid nanoprobe that enables spontaneous labelling and magnetic...
