| 中文摘要 | through electrostatic layer-by-layer (lbl) assembly, negatively charged calf thymus double stranded dna (ctds-dna), and positively charged zr4+ ions were alternately deposited on gold substrate modified with chemisorbed cysteamine. thus-prepared three-dimensional dna networks were characterized by surface plasmon resonance (spr) spectroscopy, x-ray photoelectron spectroscopy (xps) and infrared reflection-absorption spectroscopy (ir-ras). spr spectroscopy indicates that the effective thickness of dna monolayer in the (dna/zr4+), bilayer was 1.5 +/- 0.1 nm, which corresponds to the surface coverage of 79% of its full packed monolayer. at the same time, a linear increase of film thickness with increasing number of layers was also confirmed by spr characterizations. the data of xps and ir-ras show that zr4+ ions interact with both the phosphate groups and nitrogenous bases of dna and load into the framework of dna. furthermore, the interactions between this composite film and heme protein cytochrome c (cyt c) were investigated by spr spectroscopy and electrochemistry. |
