ZnO Nanostructure based Electrochemical Bio-Sensors for intra/extracellular glucose
measurement
Muhammad. H Asif
Lund University, Sweden
T
he nanostructure of zinc oxide (ZnO) such as nanorods
and nanowires has interesting nanosurfaces compare
to its bulk properties. Recently ZnO have attracted much
interest because of its semiconducting, electrochemical,
catalytic properties, being biosafe and biocompatible
morphology combined with the easiness of growth.
This implies that ZnO has a wide range of applications in
optoelectronics, sensors, transducers, energy conversion
and medical sciences. This abstract relates specifically to
electrochemical glucose biosensors for extra/intracellular
environment based on functionalized zinc oxide nanorods
for biochemical applications. To adjust the sensor for
intracellular measurements, the ZnO nanorods were grown
on the tip of a borosilicate glass capillary (0.7μm in diameter)
and functionalized with polymeric membrane or enzymes
for intracellular selective glucose sensors. The sensor in
this study was used to detect and monitor real changes of
glucose across human fat cells and frog cells using changes
in the electrochemical potential at the interface in the
intracellular microenvironment. The fabrication of such type
of device aims to explain the methodology of ions/glucose
sensing using functionalized ZnO nanorods for intracellular
environment. This nanoelectrode device paves the way to
enable analytical measurements in single living cells.
