The present invention relates to a surface modification method for improving the dispersion of nanoparticles, and to nanoparticles having improved dispersion properties prepared by the method. More particularly, the present invention relates to a method in which amphoteric compounds are bonded to the surfaces of nanoparticles to improve dispersion at the surfaces of nanoparticles. The present invention also relates to nanoparticles using the method. Both anions and cations are formed on the surfaces of the nanoparticles according to the present invention, and therefore the nanoparticles are electrically stable so as to achieve stability in a wide pH range, are stably dispersed in the event of a high concentration of salts, and the non-specific adsorption thereof is reduced. Novel specific substances or sensors having minimized non-specific adsorption may be produced using the nanoparticles of the present invention.
本发明涉及一种用于改善纳米颗粒分散性的表面修饰方法,以及通过该方法制备的具有改善分散性能的纳米颗粒。更具体地说,本发明涉及一种方法,其中将两性化合物键合到纳米颗粒表面,以改善纳米颗粒表面的分散性。本发明还涉及使用该方法的纳米颗粒。根据本发明,在纳米颗粒表面形成阴离子和阳离子,因此纳米颗粒在广泛的pH范围内具有电稳定性,即使在高浓度的盐溶液中也能稳定分散,并且其非特异性吸附减少。可以使用本发明的纳米颗粒制备新型的特定物质或传感器,其非特异性吸附最小化。
