Robert Langer is a chemical engineer, who has pioneered new technologies in the fields of biology and medicine. Through tissue engineering, he developed a new medicine delivery system that can be implanted into someone's brain. He received criticism from the scientific community when he first announced the slow release system.
Langer and a team developed microchips that can slowly deliver medicine inside a person. He hopes to expand the technology to fight more diseases.
Langer combines cells with polymer to create new organs and tissues. The cells are placed on the polymer scaffold and grow into the needed tissues.
Langer enjoyed playing with his chemistry set as a child. He studied chemistry at Cornell University and chemical engineering at MIT. He is a professor at MIT and started a school for low-income children.
At his first job, Langer found a way to cut off blood vessels that help tumors grow. A chemical needed to be added, but it had to be slow. It led him to developing his controlled release drug system.
