The present description relates to an injectable emulsion comprising an amphiphilic compound, a first phase comprising droplets including at least one perfluorocarbon compound and a second phase, which is aqueous. The droplets have a diameter dof between 0.5 pm and 5.5 pm, and the at least one perfluorocarbon compound has a boiling point above 100° C. The present description also relates to methods comprising administering such an injectable emulsion in, for example, ultrasound ablation surgery (FIG.).

Emulsion for ultrasound ablation surgery

The present description relates to a method for extracting at least one substance of interest, the method comprising the following steps: —providing an admixture comprising water, a source comprising the at least one substance of interest or at least one precursor thereof, at least one surfactant and at least one lipophilic compound; —the emulsification of the admixture, leading to the formation of an emulsion; wherein the emulsion comprises: —a continuous aqueous phase; and a discontinuous lipidic phase comprising the at least one lipophilic compound, the at least one surfactant and at least one substance of interest extracted from the source during the emulsification; wherein the method further comprises the addition of at least one cryoprotectant to the admixture and the lyophilization of the emulsion.

Process for extracting substances of interest

The present invention is in the field of surfactants to extract a platinum group metal or gold, in particular palladium, from organic compositions. In particular, the invention concerns the use of surfactants to back-extract a platinum group metal or gold, in particular palladium, from organic compositions further comprising an extractant of said platinum group metal or gold, in particular palladium from an aqueous solution.

The present invention relates to novel amphiphilic dendrimers, hereafter denoted Dendri-TAC. The present invention also relates to perfluorocarbon nanoemulsions stabilized by these amphiphilic dendrimers and their uses for in vivo diagnostic and/or for therapy, notably as theranostic tools, for detection and/or treatment of cancer.
