Abstract
The invention relates mainly to a particle comprising at least one biopolymer which is degradable under the effect of an electromagnetic wavelength, notably the wavelength of which is in the spectrum of the wavelengths emitted by the sun, this biopolymer comprising nucleosides. The invention also relates to compositions containing such particles with the aim of delivering an active principle. These particles can be used mainly in cosmetics, in dermatology, in pharmacy, in agri-food or en agro-industrials.
