In addition to internal regulation (degradation of polymers or enzymatic trigger) for drug controlled release, we are also interested in developing novel approaches for drug delivery responding to external stimuli such as magnetic or ultrasound signals. We investigate microtech devices for treating traumatic brain injury, transdermal delivery systems, photo-triggered Intravitreal implants and injectable gastrointestinal delivery devices for minimally invasive drug delivery routes. Our lab includes a highly multidisciplinary team of chemists, biologists, engineers and physicians to develop and rapidly translate new nanotechnologies to better diagnose and treat cancers and other diseases.
