| Summary: | Dopamine is a neurotransmitter and hormone that plays an important role in the
human body. Irregular dopamine regulation will lead to the formation of several
diseases such as Parkinson's, schizophrenia, and some cancers. Therefore we
need a method to detect dopamine which is fast and cheap. One method that is
often used is electrochemical detection using certain materials for the electrodes.
The material that is currently popular is graphene oxide. Graphene oxide is a
derivative of graphene with surface defects. These defects can help the graphene
oxide to be more easily composited with other materials such as metal oxides.
Metal oxides are often used because they have good catalytic properties for
electrochemical sensor applications, especially biosensors. Graphene oxide can
form composites with metal oxides so that it has good catalytic properties and
also has a large specific surface area suitable for electrochemical sensor
applications. GO-TiO2, GO-NiO, and GO-CuO composites will be synthesized
using hydrothermal method utilizing teflon-lined autoclave and tested in this
study, especially for GO-TiO2 and GO-NiO composites that have good
performance with LOD of 0.76 ?M and 0.36 ?M respectively. |
