The present invention relates to a process for manufacturing stable and monodisperse biocompatible bismuth metallic (0) nanoparticles, in aqueous solution, using a water-soluble bismuth precursor, a water-soluble reducing agent and a coating agent. The process can be carried out in continuous flow. The invention also relates to corresponding stable biocompatible bismuth metallic (0) nanoparticles having hydrophilic, hydrophobic or fluorophilic properties and uses thereof, especially medical applications thereof such as theranostic applications.
Binding an analyte can cause a change in fluorescence emission of a sensor. The change in fluorescence can be related to the amount of analyte present. The sensor can include a semiconductor nanocrystal linked to a fluorescent moiety. Upon excitation, the fluorescent moiety can transfer energy to the semiconductor nanocrystal, or vice versa.

Provided are an organopolysiloxane that exhibits good dispersion stability within not only organic oil agents but also cosmetic materials that contain a powder, and is able to produce a cosmetic material that exhibits excellent skin affinity, an organopolysiloxane that does not impart a sticky feeling, and exhibits excellent skin affinity and skin adhesion, and a cosmetic material including such an organopolysiloxane. The organopolysiloxane is represented by formula (1) below:
in which R1 represents a hydrocarbon group such as an alkyl group, R2 represents a group represented by formula (3) or formula (4) below:
in which either R4 represents a specific hydrocarbon group and R5 represents a hydrogen atom or a specific hydrocarbon group, or alternatively, at least one of R4 and R5 represents a hydroxyalkyl group, and
A represents a group containing an organosilyl group or organosiloxane residue.
