Method for preparing malonate methylidene nanoparticles, nanoparticles optionally containing one or several biologically active molecules

摘要

The invention relates to a method for the preparation of nanoparticles formed from a random polymer of at least one compound of formula (I) chemistry chemdraw filechemistry mol file;group ;R₁ and R₂, identical or different, represents a linear or branched C₁-C₆ alkyl group; ;n1, 2, 3, 4 or 5, ;characterised in that the monomer is dissolved beforehand in a water-miscible aprotic organic solvent forming, with the polymerization medium, a non-solvent mixture of the polymer formed. ;The invention also relates to said nanoparticles, which optionally contain one or more biologically active molecules, and the pharmaceutical compositions containing them.
