Conductance of Silver Modified DNA-Carbon Nanotube Nanomaterials
Description
DNA is useful for electronic applications due to its self-assembly and electronic properties. It can be improved for this purpose through the addition of metal ions. In this experiment, DNA was modified with silver ions and carbon nanotubes were attached to both ends. The DNA-CNTs were connected over a 300 nm gap between gold electrodes using cysteamine. The conductance was found to be 1.28*10-4 G0, which is similar to literature values for unmodified DNA. Therefore, modifying DNA with silver ions was not found to significantly improve the conductance. It was also found that smaller applied voltages need to be used because of electrochemistry happening above 1 V.
