The invention relates to an oil-in-water nanoemulsion for MRI, including:
an aqueous phase,
a fluorinated phase including at least one fluorinated oil,
a surfactant at the interface between the aqueous and fluorinated phases, the surfactant comprising:
at least one amphiphilic targeting ligand,
at least one amphiphilic lipid, and
at least one diblock or triblock fluorophilic compound,
as well as to the use thereof as a contrast agent.
fluorine acceptor which defluorinates perfluoroalkanes with the partial structure (Rf)2CFCF(Rf)2 to alkenes and perfluoroalkenes to dienes. Carbon catalyzes double-bond shifts, as well as cis/trans and ring-chain perfluoro-olefin isomerizations. Carbon effectively catalyzes TFE and HFP dimerizations. Less effectively, carbon catalyzes further oligomerization of TFE to give low yields of linear, internal olefins

β-cyclodextrins (CD) in aqueoussolution to varying extents, depending on the structure of both the perfluoroalkane and the cyclodextrin. β-CD readily forms insoluble inclusion compounds, including a β-CD/C9F19· complex, prepared from the stable perfluoro-1-ethyl-1,1-diisopropylmethyl radical. Under similar conditions, only trace amounts of inclusion compounds were obtained using α-CD solutions. Three hydrocarbons
根据全氟烷烃和环糊精的结构,无环和环状全氟烷烃与水溶液中的α-和β-环糊精(CD)结合程度不同。β-CD容易形成不溶性包合物,包括由稳定的全氟-1-乙基-1,1-二异丙基甲基基团制得的β-CD/ C 9 F 19 ·配合物。在相似的条件下,使用α-CD溶液只能获得痕量的夹杂物。将三种碳氢化合物与相应的全氟化碳形成α-CD和β-CD夹杂物的趋势进行了比较。

Photosensitizer particle contrast agents are suitable for medical imaging and/or photodynamic therapy. The photosensitizer particle contrast agent has a shell and a core encased by the shell. The shell consists essentially of multiple photosensitizer conjugates. Each photosensitizer conjugate consists of a photosensitizer and at least one biodegradable polymer covalently bound to the photosensitizer. The core has an echogenic contrast-enhancing material loaded therein. The photosensitizer of at least one of the multiple photosensitizer conjugates has a magnetic contrast-enhancing agent, e.g., a paramagnetic ion, chelated thereto. Methods for medical imaging use imaging compositions containing the photosensitizer particle contrast agents.
