Aminah earned her master degree and Ph.D. at Korea Advanced Institute of Science and Technology (KAIST), South Korea, under supervision of Prof. Sung-Min Choi. Throughout her master studies, she worked on the synthesis of oppositely charged one dimensional gold nanoparticles and investigated their aggregation behavior.
During her Ph.D. studies, she developed a new synthesis method to obtain various shapes of monodisperse polyhedral gold nanoparticles with tunable sizes, such as cubes, octahedra, cuboctahedra, rhombic dodecahedra, and plate/prism.
