Glucose Oxidase: An enzyme of the oxidoreductase class that catalyzes the conversion of beta-D-glucose and oxygen to D-glucono-1,5-lactone and peroxide. It is a flavoprotein, highly specific for beta-D-glucose. The enzyme is produced by Penicillium notatum and other fungi and has antibacterial activity in the presence of glucose and oxygen. It is used to estimate glucose concentration in blood or urine samples through the formation of colored dyes by the hydrogen peroxide produced in the reaction. (From Enzyme Nomenclature, 1992) EC

Electrochemical Biosensing

JoVE 5796

Electrochemical biosensors detect the binding of a target molecule by sensing an oxidation-reduction event. These sensors paved the way for modern biosensing after the invention of the glucose biosensor. This video will introduce electrochemical biosensing, show the workings of the glucose biosensor, and discuss how electrochemical biosensors are used in cancer detection.

Overview of Biomaterials

JoVE 5797

Biomaterials are materials engineered to interact favorably with biological organisms or molecules. These materials can be derived from or produced by an organism, or can even be a synthesized polymer. Engineers use these novel materials in a wide range of applications, such as tissue engineering, biosensing and drug delivery.

This video introduces common biologically derived materials, and provides examples of common techniques used to process them. Key challenges in the field are discussed, along with several applications of these methods.
