The invention discloses a preparation method of a doped nano-
enzyme preparation for treating and diagnosing
cartilage diseases as well as a product and application of the doped nano-
enzyme preparation. The preparation method comprises the following steps:
doping miscellaneous metals into single
metal oxide nano-
enzyme to obtain doped nano-enzyme; performing positive
electricity modification on the doped nano enzyme to prepare an injectable preparation; injectable formulations are used for the treatment, alleviation and diagnosis of
cartilage disease. According to the nano-enzyme preparation for
cartilage prepared by the invention, the
medication frequency can be reduced, and the injection
infection risk and economic burden can be reduced; the continuous anti-inflammatory effect is enhanced, and the protection effect on the body is prolonged; physiological
toxicity is avoided; the multi-enzyme activity can be regulated and designed, and personalized customization is carried out aiming at diseases; the method can be used for rapidly diagnosing the cartilage health degree of the joint
pathological section.
