DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS

DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS Dendrimers are a new class of synthetic polymers which have a tree or star shape like structure, with a central core, interior branches and terminal groups which embellish the surface. It can be synthesized by a repetitive step-growth polymerization process. They are highly branched and monodisperse… read more: http://www.pharmatutor.org/articles/dendrimer-novel-system-in-pharmaceuticals Crystal… Continue reading DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS
