제목 | Study of Micelle's Dynamics with Nuclear Magnetic Resonance Spectroscopy |
초록 | Block copolymer micelles have been widely used in biomedical and cosmetic fields as delivery materials because of a specific targeting and delivering drugs / anti-aging components. In order to evaluate a performance of micelle, various Nuclear Magnetic Resonance(NMR) parameters such as chemical shifts, T1, T2 relaxation time and diffusion coefficient value which represent dynamic information of a micelle core part that is flexibility and mobility are studied. Herein, we researched micelles which are composed of diblock and triblock copolymer through a high resolution NMR that is powerful method in examining atomic level information. First of all, we investigated critical micelle concentrations(CMC) and thermo stability of core parts following a change of concentration and temperature respectively by using the NMR parameters. Then, stability differences of delivery fuctional part were confirmed in existence / nonexistence condition of lecithin which is an emulsifying agent. Additionally, with the preceding whole data, we evaluated a performance of micelles as delivery materals. |
