Over the past few years, virus detection techniques have become increasingly important because of the frequent occurrence of new pathogenic virus strains. At present, there are two well-established diagnostic techniques for viruses: immunoassay and DNA-/RNA-based methods. Immunoassay, considered the gold standard, uses either direct immunofluorescent assay or membrane enzyme-linked immunosorbent assay...
The AC impedance spectroscopy of Chicken Infectious Laryngotracheitis Virus (ILTV, gallid herpesvirus 1) was measured using atomic force microscopy (AFM). The result indicates a 30% difference in the absolute impedance values between the control and virus samples within a 10-65 kHz frequency range. Using an equivalent circuit of the systems and an electrical curve fitting program, the data shows the...
Molecular wire construction using DNA-directed self-assembly of multi-walled carbon nanotubes (MWNTs) has been attempted. MWNTs were selected owing to their exceptional electrical and structural properties. DNA, which possesses specific molecular recognition properties, served as the engine for the assembly. Non-crosshybridizing (NCH) sequences were designed to impart specificity and high throughput...
