Container from linear polymer is the polymer main chain and side as the container the primitives of the novel, the structure of the tree-polymer. Use of the drug carrier can be made hydrophobic drugs to the target, for the drug, drug side effects.

The tree cladodification polymer is by the linear polymer principal chain and one kind which is composed as the side group tree cladodification element new, the structure neat shape of tree polymer.Uses this medicine carrier to be able to cause the hydrophobic medicine target tropism, pointed obtain

Branches of polymers are linear polymer main chain and side groups made up of branches of the primitive tree-like polymers, structure of a new regular. Using the drug carrier could turn a hydrophobic drug targeting, targeted improved drug side effects decrease.
