description |
Here we reported the gold nanoparticles
(GNPs) decorated ZnO thin films based biosensor for the
detection of pork DNA hybridization. Label-free DNA
detection is increasingly important in bio diagnostics, food
analysis and forensic investigations. The capacitance, permittivity
and impedance profiles of the biosensor clearly
differentiated the complementary and non-complementary
target DNA detection using low-cost dielectric analyzer. In
this study, GNPs were used to create an attachment surface
between the ZnO thin films and the thiol-modified probe
DNA and to enhance the sensitivity of the biosensor up to
~59 %. The ZnO thin films and 35 ± 5 nm in diameters of
GNP-coating on their surfaces were confirmed with various
types of measurement such as FESEM, XRD, EDX and
UV–Vis spectroscopy. |
