Computer programming language automates "laboratory-on-a-chip" technologies and has potential to improve and reduce cost of healthcare.
A research team at the University of California, Riverside has created a computer programming language that will automate "laboratory-on-a-chip" technologies used in DNA sequencing, drug discovery, virus detection and other biomedical applications.
A laboratory-on-a-chip is a device that integrates laboratory functions on a chip that is only millimeters or centimeters in size. The technology allows for the automation and miniaturization of biochemical reactions. It has the potential and to improve and reduce the cost of healthcare.
"If you think of the beginning of computers they were basically tools to automate mathematics," said Philip Brisk, an assistant professor in the Department of Computer Science and Engineering at UC Riverside's Bourns College of Engineering. "What we are creating is devices that could automate chemistry in much the same way."
The most recent laboratory-on-a-chip devices are equipped with integrated electronic sensors, similar in principle to those used in today's smart phones and tablet PCs. These sensors enable scientists and health care professionals working with the devices to analyze the sensor data to make informed decisions about future analyses to perform.
Brisk and his research team are funneling the sensor data into a computer, facilitating automated decision making, rather than employing a human-in-the-loop.
"We are really trying to eliminate as much human interaction as possible," Brisk said. "Now, you have a chip, you use it and then you analyze it. Through automation and programmability, you eliminate human error, cut costs and speed up the entire process."
The team started with an existing biological programming language, BioCoder, developed by Microsoft's research office in India. It was originally created to improve the reproducibility and automation of biology experiments by using a programming language to express the series of steps taken.
The UC Riverside team modified BioCoder to process sensor feedback in real-time. Using a software simulator to mimic the behavior of a laboratory-on-a-chip, they proved it works. Now, in conjunction with William Grover, an assistant professor of bioengineering at UC Riverside, they plan to build a prototype chip that can be used for real world applications.
