3D Printed Hydrogel Device for Novel Drug Delivery System

A Geneva drive is a two-geared mechanism which turns a continuous rotation into an intermittent rotary motion, thus producing very precise ticks forward. Bioengineers at Columbia University have 3D printed a 15-millimeter Geneva drive, using squishy hydrogel, in order to make a biocompatible micromachine that can be used to deliver doses of drugs on command once it's been implanted inside your body. The device was created in Sia Lab, where the principal investigator, Samuel Sia, Columbia University professor of biomedical engineering, spends his days working with microfluidics. He has already tested the iMEMS in lab mice with osteosarcoma (bone cancer), and the positive results were published today in the Science Robotics journal.
