Beschreibung
Zusammenfassung:	The invention discloses tree-type high-molecular polyamide-amine wrapped platinum nanometer particles, and its preparation method, wherein the tree-type high-molecular polyamide-amine is shown as a formula (1). The tree-type high-molecular polyamide-amine and potassium chloroplatinate are used as raw materials, a sodium borohydride solution is used in a reduction reaction, and the tree-type high-molecular polyamide-amine wrapped platinum nanometer particles are omitted. The invention further provides application of the tree-type high-molecular polyamide-amine wrapped platinum nanometer particles as a catalase simulation enzyme. The tree-type high-molecular polyamide-amine wrapped platinum nanometer particles has small cytotoxicity, can effectively and safely remove active oxygen in a cell, can be used as the catalase simulation enzyme, and has advantages of high efficiency and low toxicity.
