Researchers from National Taiwan University provide details of new studies and findings in the area of DNA research
Published in Gene Therapy Weekly, February 19th, 2009
"We demonstrate a rationale for using GaN nanowires (GaNNWs) in label-free DNA-sensing using dual routes of electrochemical impedance spectroscopy (EIS) and photoluminescence (PL) measurements, employing a popular target DNA with anthrax lethal factor (LF) sequence. The in situ EIS reveals that both high surface area and surface band-bending in the nanowires, providing more binding sites and surface-enhanced charge transfer, respectively, are responsible for the enhanced sensitivity to surface-immobilized DNA molecules," researchers in Taipei, Taiwan report.
"The net electron-transfer resistance can be readily deconvoluted into two components because of the coexistence...
