How to Build Your Own Microfluidic Device

Dr. Ol from Science Buddies guides you through creating a microfluidic device using polystyrene sheets. The video covers the materials needed, design and assembly process, and the heating and testing of the device. Microfluidic devices have applications in various fields, and this project demonstrates their basic construction and functionality.

What type of plastic is required to build a microfluidic device in this project?

• Polyethylene

• Polystyrene

• Polycarbonate

• Polyvinyl chloride

What is the first step in designing your microfluidic device?

• Trace the design on the top sheet

• Cut out the design on the middle sheet

• Preheat the oven

• Glue the sheets together

Why is it important to trace around your design on the polystyrene sheets?

• To make it easier to align the sheets when layered

• To ensure the sheets are the same size

• To mark where to apply glue

• To create a decorative pattern

At what temperature should the oven be preheated for the shrinking process?

• 300 degrees Fahrenheit

• 330 degrees Fahrenheit

• 350 degrees Fahrenheit

• 370 degrees Fahrenheit

What can be used to test if the channels in the microfluidic device allow fluid to pass through?

• Saltwater

• Diluted dye

• Oil

• Vinegar
