Preparation of polydiacetylene, Quantum dot-assembled silica nanoparticles and its application for dual-modal imaging |
| 초록 |
Polydiacetylene (PDA) has been used in various fields because of its interesting properties; the polymerization ability by UV exposure without using any initiators or catalysts and the chromic nature by external stimuli, such as heat, stress and molecular recognitions. Here, we immobilized PDA on the surface of quantum dot (QD) embedded silica nanoparticles (PDA-QD2) and studied its optical properties. The prepared PDA-QD2 exhibits a blue color without fluorescence. After inducing stress, PDA-QD2 changed its color from blue to red with fluorescence of PDA. We recognized the QD fluorescence over the PDA background that could be used as multiplexing detection. Moreover, our PDA immobilization methods are successfully applied to various kinds of QD2. |
