Low-cost Immobilized Enzyme Glucose Sensor based on Laminar Flow

Abstract

In modern medicine, glucose plays an important role in our body because glucose is the basic nutrition of human body and we can find important human healthy information through it. With the development of medicine, many diseases require glucose of blood tests including genetic diseases. People has known that the production and consumption of glucose of blood in a normal people is in a state of dynamic equilibrium and is maintained at a relatively stable level. Once the level higher or lower than the normal level, human probably have some diseases base on concentration of blood sugar like Diabetes or Hypoglycemia.Many schools or research institutions have tested biofuel glucose sensors based on laminar flow, which has desired effect in electricity generation. So in this experiments, we will find a new way to test glucose of blood by microfluidic fuel cell, and use buffer solution contained glucose to simulate blood. Then we will introduce material of electrodes, enzymes immobilization, and how to make a laminar flow channel. Finally finding the relationship between concentration of glucose and electricity current, which can show the possibility of quick detection in blood sugar. Current research shows the great potential of this cheap disposable glucose sensor, and more phenomena and applications based on laminar flow biofuel cell can be discovered in the future.
