摘要

Deoxyribonucleic acid (DNA), as the most important molecule in nature, holds promise as a key element of the molecular electronics as its utilization in the synthesis of electronic devices such as micro and nano sensors has increased remarkably during the recent years. Our work is devoted to an experimental study of the electrical resistivity of a gold-DNA-gold (GDG) structure in the presence of a variable external magnetic field. The DNA strands, extracted by the PCR method, were used to fabricate the GDG structures. The resistivity of the structure was found to rise sharply with the magnitude of the exerted magnetic field due to onset and progression of the cyclotron effects in charge carriers. Such a distinct current-voltage signature can possibly be employed for realization of an accurate magnetic sensor.
