A method using the color intensity of light to measure chemical concentrations may soon help speed the processes for developing medications, printers, and other products.
A team from Purdue University created the new approach for using a light-sensitive device to measure the concentration of chemicals used in applications such as biological research and the manufacturing of consumer goods and food products.
“Our concept significantly reduces the complexities associated with performing colorimetric analysis at the smaller scales necessary for research and production,” said Justin Weibel, a research associate professor in Purdue’s College of Engineering. “Our sessile-droplet approach allows for passive…READ MORE
