Microfluidic chips have attracted much attention in the areas such as clinical diagnostics and analytical chemistry as they provide miniaturized platforms of conventional analysis techniques. The microfluidic chip allows faster and cheaper analysis consuming much smaller amounts of samples and reagents than conventional methods. On the other hand, conjugated polymer is excellent sensor materials that have unique feature. For example, polydiacetylenes (PDAs) exhibit distinctive features of visible color change and fluorescence emission by environmental stimulus such as temperature, pH, pressure, molecular recognition, and etc. To investigate the feasibility of the integration of PDA sensors onto a microfluidic chip, we have employed a hydrodynamic focusing technique. This presentation introduces the development of microfluidic conjugated sensor chip responding to cyclodextrin, pH, and heat. We also discuss a novel microfluidic method to generate PDA liposomes of a uniform size. |
