Enzyme-based electrodes are a representative application of
immobilized enzymes for diagnosis and treatment of various diseases.
The high specificity and reactivity of immobilized enzymes
are being exploited in the biosensing field. These studies have resulting
in replacing existing diagnostic tools such as glucose test
strips, chromatography, mass spectroscopy, and enzyme-linked
immunosorbent assays with faster and cost effective diagnostic
devices [67]. These devices can be used to provide an early signal
of metabolic imbalances and assist in preventing and curing
diabetes and obesity [82].
