The origin of chirality is coming from the structural asymmetry. Chiral structures such as helix have no any symmetric point, line, and plane. So it cannot be overlapped with its symmetric images. This figures can give different interactions with right- and left-handed circular polarized light. Here, we fabricated nature-inspired helix-mimetic optical activity modulator with self-assembled magnetoplasmonic nanochains. In the polymer gel and solution, we can assemble magnetic nanochain by external magnetic field. In addition, we can control its structures by physical force and magnetic field arrangement. As a results, circular dichroism signal intensities and sign can be changed. |
