Abstract: Disclosed are a leaf vein absorption method and a functional modification material for plant. The functional modification material has a covering with a functional material and a protector with a polymeric stabilizing material. The functional material is a unitary, a multivariate, or a high-entropy compound, or a semiconducting or an optoelectronic material. The covering covers a surface of a plant organ, wherein the covering comprises a stomata expansion material to enable the functional material to be absorbed into a plant through stomata. The protector covers a surface of the covering. The functional material is capable of maintaining its functional presence on a surface of the plant until the plant organ undergoes natural apoptosis. Through an absorption technology of leaf veins on the surface of the plant, special functions can be achieved without modifying or implanting plant genes.

Abstract: A method for preparing an inorganic nano-material is provided. The method includes steps of providing a first solution including plural metal ions; mixing the first solution with a surfactant and adding a reduction agent to generate a second solution, wherein the second solution generates plural metal atoms reduced from the plural metal ions; and adding an oxidation agent into the second solution for oxidizing the plural metal atoms so as to generate plural metal oxides and form the inorganic nano-material.
