The invention discloses a magnetic pollen nano carrier using pollen as a template and a preparation method thereof. Wherein, the magnetic pollen nanocarrier includes: degreasing pollen particles, magnetic nanoparticles, polymer functional layers, gold nanoparticles or antitumor drugs. The magnetic pollen nano carrier has magnetism; a polymer functional layer is deposited on the surface of the pollen particles; gold nanoparticles or antitumor drugs are deposited on the surface of the polymer functional layer. Since pollen nanocarriers are magnetic, the directional movement of the carrier can be achieved by controlling the magnetism, thereby driving the directional movement of surface catalysts or anti-tumor drugs, which can achieve site-specific catalysis of organic pollutants and site-specific delivery of anti-tumor drugs. At the same time, because pollen can be metabolized in the body, the metabolized products will not have toxic and side effects on the body, which helps to improve the safety of drugs. |
