Polymer has played an important role as an organic material, and its property of responsiveness to stimuli such as temperature, pH, ion and light has drawn attention for applications as a smart material. DNA also has been an interesting subject as an organic material itself as well as a programmable gene code; its properties such as target-specific capturing and pH-responsiveness have been studied. Even though various studies have been reported to relate these two different fields, they still have a good many things to find inbetween. Here, we synthesized a hybrid gel with polymer backbones and DNA moieties having pH-responsive properties both. This hybrid gel is obtained by sol-gel transition in pH showing swelling and shrinking behaviors. By this study, we report a new mean of pH-responsive system by the polymer-based DNA hybrid gel suggesting its potential in the fields of controlled drug delivery, sensors, actuators, nano-machine, and microfluidics. |
