    摘要: An aqueous synthesis methodology for the preparation of silica nanoparticles (SNPs), core-shell SNPs having, for example, a size of 2 to 15 nm and narrow size-dispersion with size control below 1 nm, i.e. at the level of a single atomic layer. Different types of dyes, including near infrared (NIR) emitters, can be covalently encapsulated within and brightness can be enhanced via addition of extra silica shells. The surface may be functionalized with polyethylene glycol (PEG) groups and, optionally, specific surface ligands. This aqueous synthesis methodology also enables synthesis of 2 to 15 nm sized fluorescent core and core- shell aluminosilicate nanoparticles (ASNPs) which may also be surface functionalized. Encapsulation efficiency and brightness of highly negatively charged NIR fluorophores is enhanced relative to the corresponding SNPs without aluminum.

    摘要: This invention relates to a method for tracking stem cells characterized in that the stems cells are labelled with at least one fluorescent conjugated polymer nanodot and the fluorescence of the labelled cells is detected. The fluorescent conjugated polymer nanodot comprises a conjugated polymer such as poly(9,9-dihexylfluorene-alt-2,1,3-benzoxadiazole) (PFBD) capped with an amphiphilic co-polymer such as DSPE-PEG2000 (1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE)-conjugated polyethylene glycol) and DSPE-PEG 2000 maleimide. The method allows for the tracking of stem cells over long periods of time after transplantation exceeding 25 days. The stem cells are not compromised in their behaviours of proliferation, migration, differentiation and secretome by the labelling method of the invention. The method may be useful as a research tool in regenerative stem cell medicine. Corresponding stem cell tracking kits are also disclosed as well as stem cells labelled with the fluorescent conjugated polymer nanodots.

    摘要: The present invention refers to a pharmaceutical formulation for injection comprising fluorescent nanoparticles as in vivo diagnostics. The present invention relates to an injectable pharmaceutical formulation for human medicine and/or veterinary use, comprising 17% to 20% per weight of poloxamer 407 and 3% - 15% per weight of poloxamer 188, 0.10 nM to 10.0 μΜ fluorescent nanoparticles and water or an aqueous buffer, wherein the pharmaceutical formulation is liquid at 4°C - 32°C and forms a gel at about 37°C, their use as an in vivo marker and methods of their preparation. The inventive formulation is useful for local control and prevention of spreading/diffusion of nanoparticles, and thus allows full utilization of their quantum physics properties for example as a tool to enable surgical precision of tumor removal; even without tumor specific epitope binding antibodies.
