| dc.description.abstract | Glucose plays an important role in metabolism, and is a source of energy for human activities.
However, consuming too much glucose leads to metabolic diseases, most typically diabetes, which
is considered one of the most dangerous and deadly diseases in the world. Therefore, many
methods have been developed to test glucose concentration, of which the colorimetric method is
the most popular. However, natural enzymes used in this method are often susceptible to
environmental influences and are expensive in the market. Thus, to replace the natural enzyme in
the process of detecting glucose concentration, an extremely sensitive colorimetric glucose sensor
was fabricated using a hybrid structure of manganese ferrite oxide–graphitic carbon nitride
(MnFe2O4/g-C3N4). In this thesis report, the synthesis of MnFe2O4 and MnFe2O4/g-C3N4 by co precipitation method was successfully carried out. At the same time, the evaluation of the
peroxidase-like catalyst properties was also carried out. Finally, the thesis study evaluated the
ability to detect different hydrogen peroxide and glucose concentrations using different synthetic
catalysts. With the help of g-C3N4, the MnFe2O4 catalyst showed more sensitivity and accuracy
than without the presence of g-C3N4 | en_US |
