of AuNPs have been reported and reviewed, which include chemical reduction, photolysis, radiolysis, sonoc- hemistry and thermolysis reduction, two-phase synthesis methods and etc. Among them, the most convenient and popular method is chemical reduction in which metal ions are reduced by a reducing agent such as sodium borohydride, sodi- um citrate, hydrogen, and alcohol. TheoryIn general, preparation methods for nanoparticles make use of capping agents, such as surfactants, polymers or biomaterial, in order to confine the growth. Occasionally, the selective or preferential adsorption of ca

Polymer의 특징Core-shell Polymer는 폴리머 조성이 다른 고분자 입자의 블랜딩과 공중합 폴리머입자의 물성과는 달리 한 입자 내에서도 상반된 물성을 동시에 나타내는 특성으로 인하여 페인트, 접착제, 부직포 등의 학문적, 공업적 응용가치가 크다. V.
