Abstract:
Gadolinium chelate and Quantum Dots (QDs) decorated single walled carbon nanotubes (SWNTs) nanohybrids (SWNT-Gd-QDs) were designed for dual-modal cellular imaging via magnetic resonance imaging (MRI) and optical imaging. The nanohybrids were prepared via a simple and novel layer-by-layer (LBL) assembly in combination with covalent connection strategy. The SWNT-Gd-QDs nanohybrids showed a strong near-infrared photoluminescence (PL) emission at room temperature and enhanced T1-weighted and T2-weighted MRI signals in water. Thus, the nanohybrids combine magnetic and fluorescent properties and can

Abstract:
In this paper, we demonstrate multifunctional upconversion nanoparticles with intense near-infrared emission and unique magnetic properties for dual-modal upconversion luminescent bioimaging and T2-weighted magnetic resonance imaging. High-quality BaYbF5:Tm3+ nanoparticles are synthesized via a hydrophobic method and then converted to be hydrophilic via a hydrochloric acid treatment. The as-synthesized nanoparticles are cubic phase and about 6 nm in diameter with narrow size distribution. The intense near-infrared emission makes these nanoparticles can be acted as bio-probes in upconversion lu

Abstract:
We report a reliable and facile procedure to prepare near infrared fluorescence (NIRF)-magnetic resonance dual-modal imaging probes (DMIPs) using Cy5-labeled, Gd–Al co-doped mesoporous silica nanoparticles. High intensity NIRF and a relaxation rate (17.7 mM<sup>−1</sup>s<sup>−1</sup>) can be observed. Furthermore, the DMIPs in saline were injected into mice through the tail vein for imaging.

Abstract:
Dual-modal imaging by combining magnetic resonance (MR) and near-infrared (NIR) fluorescence can integrate the advantages of high-resolution anatomical imaging with high sensitivity in vivo fluorescent imaging, which is expected to play a significant role in biomedical researches. Here we report a dual-modality imaging probe (NIR/MR-MSNs) fabricated by conjugating NIR fluorescent heptamethine dyes (IR-808) and MR contrast agents (Gd-DTPA) within highly aminated mesoporous silica nanoparticles (MSNs-NH2). The dual-modality imaging probes NIR/MR-MSNs possess a size of ca. 120 nm. The NIR/MR-MSNs

Abstract:
Upconverting nanoparticles (UCNPs) are promising, new imaging probes capable of serving as multimodal contrast agents. In this study, monodisperse and ultrasmall core and core–shell UCNPs were synthesized via a thermal decomposition method. Furthermore, it was shown that the epitaxial growth of a NaGdF4 optical inert layer covering the NaGdF4:Yb,Er core effectively minimizes surface quenching due to the spatial isolation of the core from the surroundings. The mean diameter of the synthesized core and core–shell nanoparticles was ≈8 and ≈16 nm, respectively. Hydrophobic UCNPs were converted int

Abstract:
L’imagerie par fluorescence (IF) et l’imagerie de résonance magnétique (IRM) comptent parmi les outils de diagnostic les plus efficaces. Dans ce contexte, des QDs possédant à la fois des propriétés fluorescentes et magnétiques sont d’un grand intérêt en tant que sondes bimodales. Dans ce travail, des QDs Ag-In-Zn-S (AIZS) et Ag-In-Ga-Zn-S (AIGZS) ont été préparés et dopés afin de développer de nouvelles sondes de sondes bimodales pour l’IF et l’IRM. Des QDs AIZS très fluorescents ont été préparés en milieu organique à l’aide de DDT et d’OAm comme ligands. Les QDs Mn:AIZS possèdent des propriét
