Reversible assembly state of plasmonic nanoparticles driven by controlling liquid crystalline defect under multi-stimuli system

The main research theme of the project is to achieve reconfigurable assembly state of plasmonic NPs by controlling its trapping agent, LCs, under multi-stimuli system. There are two kinds of multi-stimuli LC control platform; one is static system in which anchoring, rubbing, and confinement can be modified, while the other is dynamic system which is subjected under electric field plus the three stimuli of the previous system.
As the fabrication method for LC control template is based on soft-imprinting technique, it offers an advantageous aspect, simple and cost-effective manufacturing process, compared to the fabrication process of contemporary research. The change in assembly state will be analyzed via various optical spectrometers including Polarized Optical Microscopy(POM), Fluorescence Microscopy(FM), and Surface-enhanced Raman Spectroscopy(SERS).
