碩士 / 國立臺灣科技大學 / 材料科學與工程系 / 99 / Hydrogen bonding between complementary bases of nucleic acids plays a key role in self-aggregation processes and the spatial arrangement of biological macromolecules. This unique supramolecular performance of nucleic acids has stimulated us to explore the possibilities of utilizing these features for the development of advanced artificial systems for various applications.
The hydrogen-bonding interactions and the biocomposites poly(N-isopropylacrylamide) (PNIPAAm) blended with herring sperm DNA were studied on the function of the blend composition by using thermogravimetry analyzer (TGA), differential scanning calorimetry (DSC), ultraviolet−visible (UV-Vis), scanning electron microscope (SEM), transmission electron microscope (TEM), contact angle (CA), dynamic light scattering (DLS) and semiconductor device analyzer (SDA).
PNIPAAm/DNA exhibit a sharp but continuous transition at around 32 °C, from an elongated coil to a collapsed compact state. The PNIPAAm brushes were grafted on the silicon surface by using click reaction. According to the thermo-responsive property of PNIPAAm brushes, the capture-release application for herring sperm DNA was investigated by X-ray photoelectron spectroscopy (XPS).
