A poly (acryl acid) (PAA) post-treatment method is performed to modify the surface charge of ZnO nanospheres, hematite nanocubes, and Ag nanoprisms from highly positive to very negative by adjusting the PAA concentration, to and greatly modify their photoluminescence, cytotoxicity, magnetism, and surface plasmon resonance. This method provides a general way to tune the nanoparticle properties for broad physicochemical and biological applications.
采用聚（丙烯酸）（PAA）后处理方法，通过调节 PAA 浓度，将 ZnO 纳米球、赤铁矿纳米立方体和 Ag 纳米棱柱的表面电荷从高度正电荷修饰为非常负电荷，从而极大地修饰它们的光致发光、细胞毒性、磁性和表面等离子体共振。该方法为调节纳米粒子性质提供了一种通用方法，可广泛应用于物理化学和生物学领域。
