Claim 0:
1. A method for degrading an organism, comprising:
providing a composite structure, wherein the composite structure comprises:
a degradation activity donor having a piezoelectric property, wherein the degradation activity donor is a two-dimensional material with a non-centrosymmetric structure; and
a supporter carrying the degradation activity donor, wherein the degradation activity donor is completely or partially covered by the supporter, and the supporter is made of a polymer or asphalt;

conducting a contacting step, wherein the composite structure is contacted with a medium, and the medium comprises the organism and water; and
conducting a degrading step, wherein a mechanical perturbation is generated in the medium to polarize the degradation activity donor, and a separation of an electron-hole pair is generated for degrading the organism.
