A geometric structure analyzing method, a geometric structure analyzing system, and a computer program product are provided, to analyze a two-dimensional geometric structure of a model composed of at least one magnetic building block. A magnetic field intensity image of the model is obtained, and a shape of the magnetic field intensity image is used as a contour of the model. The contour of the model is skeletonized to obtain the two-dimensional geometric structure of the model, and the two-dimensional geometric structure is displayed on a display panel. Therefore, a user is allowed to control the two-dimensional geometric structure on the display panel by manipulating the model, to achieve interactive effects including visual and tactile feedbacks.

A fabrication method of nanoparticles is provided. A substrate having a plurality of pillar structures is provided and then a plurality of ring structures is formed to surround the plurality of the pillar structures. The inner wall of each ring structure surrounds the sidewall of each pillar structure. A portion of each pillar structure is removed to reduce the height of each pillar structure and to expose the inner wall of each ring structure. The ring structures are separated from the pillar structures to form a plurality of nanoparticles. Surface modifications are applied to the ring structures before the ring structures are separated from the pillar structures on the substrate.
