dc.description.abstract | In the recent years, characterization of nanomaterials and using them in sensing
applications gain considerable attention. Increased research on nanotechnology
brings new materials and techniques that come with many unsought properties.
Additionally, novel materials and concepts have created new demands for new
characterization techniques. In this thesis, our main aim is to characterize novel
materials and develop new techniques to use nanotechnology in sensing applications.
Graphene is one of the most important material in nanotechnology found in the
recent years. In this thesis, we have characterized and explain the electrochemical
behavior of graphene oxide. During the experiments, novel properties of
graphene oxide have been revealed. Foundings paved the way for new applications
of graphene.
Recent studies in plasmonic materials made SERS (Surface-Enhanced-Raman-
Spectroscopy) an important characterization tool used in nanotechnology. SERS
is a powerful technique for chemical speci c and label free analysis of low concentration
materials. In this thesis, we have used SERS to build an arti cial nose
for detection of VOCs. SERS substrates have been fabricated and used for the
experiments. Experiments showed that our technique could detect many VOCs
and could be used for several applications such as explosive and drug detection.
There is a strong need for easy and cost e ective biosensors especially for homecare
applications. Recent advances in nanotechnology help us to develop cost
e ective techniques. Reducing costs could make biosensors more accessible for
end user applications such. In this thesis, we have developed a biosensor platform
by using SPR (Surface Plasmon Resonance) for pathogen detection. Experiments
showed that our device could detect 102 pathogens without labeling. Our aim is
to improve this platform for rapid food analysis and home-care applications. | en_US |
