A lab in the Department of Ophthalmology and Visual Sciences needs a device to accurately and efficiently deliver 5µL drops of experimental drugs into the cornea of the eye for glaucoma therapy testing in animals. Currently, the client uses standard micropipettes which deliver exactly 5µL drops, but this method is time consuming, poses a danger to the safety of the animal and makes drop placement difficult. The objective is to optimize accuracy, efficiency, and animal safety in optical drug delivery.
The team has completed two prototypes and the final design report.
