Immobilization of Proteins and Controlled Dispersion of Single Walled Carbon Nanotubes Using Nitrilotriacetic Acid-End Functionalized Polystyrenes |
| 초록 |
We describe the immobilization of His6-GFP and controlled dispersion of single walled carbon nanotubes (SWCNTs) using nickel complexed nitrilotriacetic acid-end functionalized polystyrene (Ni-NTA-PS) by conjugation between the protein and the polymer in phosphate buffer solution (PBS). We synthesized Ni-NTA-PS by atom transfer radical polymerization (ATRP) using a nitrilotriacetic acid (NTA) initiator. The diameter of the dispersed SWCNTs was measured by transmittance electron microscope (TEM). The dispersion of SWCNTs and immobilization of His6-GFP were controlled by addition of excess imidazole. It was found that the immobilized His6-GFP was more stable than free His6-GFP in organic solvent (PBS/DMF, 1/1, v/v). |
