Abstract: The invention relates to a method of producing microcapsules containing a material to be encapsulated. The method is characterized in that a mixture of at least one solubilized vegetable protein and a polyelectrolyte with an opposite charge to the protein is subject to complex coacervation in an aqueous medium, possibly followed by hardening, in the presence of the material to be encapsulated. The invention also relates to the microcapsules provided by the method and their uses in pharmaceutical, veterinary, cosmetic, agrofood, chemical or biomedical compositions.

Abstract: The invention relates to a filament comprising thermoluminescent particles that are evenly distributed in a polymer matrix, characterized in that the polymer matrix is a thermoplastic polymer having sufficient adhesion with respect to said thermoluminescent particles in order to ensure the cohesion of said filament and being such that the thermoluminescent response (signal) of the filament corresponds substantially to the dose of radiation absorbed and obtained after the filament is placed in contact with a physiological medium. The invention also relates to a method for thermoluminescence-based measurement of doses of beta radiation delivered by a transmitter on a target organ of a mammal, characterized in that a group of inventive filaments is introduced to the desired spot, whereby part of the length of said filaments remains outside the irradiated area, and in that the filaments are removed after irradiation and thermoluminescence is determined.
