(FR) PLAQUETTES DE SYNTHÈSE
Abstract
(EN) Provided herein are various functionalized particles comprising a shell, dendritic linkers, and functional moieties. The dendrimer linkers allow very large numbers of functional moieties to be bound to the shell. The functional moieties may comprise peptides which synergistically promote platelet aggregation and hemostasis in wounded tissues. The functionalized particles may further be effectors of wound healing, thrombolysis and other functions, depending on the selection of functional moiety. Functionalized polymers having these functions are provided as well.
(FR) L'invention concerne diverses particules fonctionnalisées comprenant une coque, des lieurs dendritiques, et des fractions fonctionnelles. Les lieurs dendrimères permettent à de très nombreuses fractions fonctionnelles d'être liées à la coque. Les fractions fonctionnelles peuvent comprendre des peptides qui promeuvent de façon synergique l'agrégation plaquettaire et l'hémostase dans des tissus lésés. Les particules fonctionnalisées peuvent en outre être des effecteurs de la cicatrisation des plaies, de la thrombolyse et d'autres fonctions, selon la sélection de fragment fonctionnel. La présente invention concerne en outre des polymères fonctionnalisés ayant ces fonctions.
