Materials World Modules

An Inquiry & Design-Based Science, Technology, Engineering, and Mathematics (STEM) Education Program

Mini Biosensors Module

■ Making a Peroxide Biosensor
■ Testing a Cholesterol Biosensor

Design Project
■ Designing a Glucose Biosensor

Through the following key select activities, students investigate the use of biological molecules as materials and use enzymes as chemical sensors in the design of diagnostic tests for peroxide, cholesterol, and glucose.

MWM will give students an opportunity to understand the world around them in a way they have never experienced before. The modules promote an awareness of the roles science and technology play in society and guide students to take increased control of their work.

Activity 3: Making a Peroxide Biosensor
Students learn about biosensor design by using peroxidase and an indicator molecule to make a peroxide biosensor. They learn about the concepts of dynamic range, detection limit, and biosensor accuracy by testing their biosensor to determine whether or not it can measure different concentrations of peroxide.

Activity 4: Testing a Cholesterol Biosensor
Students use two linked enzymatic reactions and an indicator molecule to make a cholesterol biosensor. They then use their biosensor to try to determine the cholesterol levels in "patient" samples of unknown concentrations.

Design Project: Designing a Glucose Biosensor
Students use what they have learned about enzymes, indicator molecules, and biosensors to design, test, and evaluate a glucose biosensor.

Folk Remedies

In South America, some people treat the bite of a highly poisonous reptile – the fer-de-lance – by applying a potion of an extract of a beautiful native plant, Latin name Aristolochia Odoratissima.
