Christopher Rivet Is One of Three Finalists for the $30,000 2012 Lemelson-MIT Rensselaer Student Prize <\/p>\n
Newswise Troy, N.Y. Christopher Rivet has successfully married two powerful bioengineering technologies to develop a new method for delivering drugs directly to an injury site and jumpstarting the process of tissue regeneration. His innovation could be an important new tool in preventing paralysis resulting from spinal cord trauma, cancer, diabetes, or a host of other diseases. <\/p>\n
Rivet, a doctoral student in the Department of Biomedical Engineering at Rensselaer Polytechnic Institute, is one of three finalists for the 2012 $30,000 Lemelson-MIT Rensselaer Student Prize. A public ceremony announcing this years winner will be held at 6:45 p.m. on Wednesday, March 7, in the auditorium of the Rensselaer Center for Biotechnology and Interdisciplinary Studies. For more information on the ceremony visit: http:\/\/www.eng.rpi.edu\/lemelson<\/a> <\/p>\n Rivets project is titled A Hydrogel and Electrospun Fiber Composite Material, and his faculty adviser is Ryan Gilbert, assistant professor of biomedical engineering at Rensselaer. <\/p>\n Sadly, there is no shortage of situations that lead to a loss of functioning tissue and, in turn, paralysis. These circumstances can range from the surgical removal of a tumor, to untreated bedsores, to a spinal cord injury stemming from a gunshot wound or traffic accident. All of these situations require action first to stop the progression of the injury, and secondly to restore function to the damaged tissue. However, there is currently no treatment, short of receiving a transplant from a donor, to simultaneously pursue both goals and more effectively mitigate the onset of paralysis. <\/p>\n Rivets patent-pending invention pairs electrospun fibers with hydrogels to help solve this important societal need. He has developed a new way to disperse nanoscopic electrospun fibers, which can prompt and guide tissue regeneration, within injectable, drug-infused hydrogels. The result is an advanced biomaterial that can mimic and serve as a temporary replacement for living tissue. <\/p>\n For example, potential target could be a patient who had a large bone tumor removed, leaving behind a hole that is too large for the body to recover from on its own. The surgeon may elect to use a hydrogel. Injected as a liquid, the hydrogel would firm up and fill in the unique shape of the void. Hydrogels can be treated with different drugs to help stop progression of the injury, and the gels can be tuned to match the mechanical properties of the tissue their replacing. However, hydrogels cannot carry the appropriate chemical cues to guide regenerative nerve cells into and out of the injury site. This means hydrogels alone are not a winning strategy for combating the onset of paralysis. <\/p>\n Rivet has incorporated electrospun fibers, which are spun from polymer and can carry guidance cues and promote functional recovery, into hydrogels. The end result is a complex system that can deliver multiple drugs as well as the necessary guidance cues to coax nerve cells through the injury site and kick start the process of regeneration. As the patients body tissue regenerates, the hydrogels and electrospun fibers simply dissolve harmlessly. Rivets system is also highly adaptable, as different electrospun fibers can be matched with various hydrogels to achieve specific goals. <\/p>\n When not in the lab or classroom, Rivet enjoys spending time outdoors. If hes not skiing, cycling, or hiking, you can probably find him on the lake fishing. At home in Grand Blanc, Mich., Rivets family and friends are rooting for him to win the $30,000 Lemelson-MIT Rensselaer Student Prize. His mother is a high school math and science teacher and his father works for the United Auto Workers labor union. Rivets older sister is a laboratory manager at Kettering University. <\/p>\n Rivet was curious and creative as a young student, and he strives to foster those virtues in others. He is an active mentor in local elementary schools and high schools, sparking the interest of students and encouraging them to seek out opportunities to study and work in the fields of science, technology, engineering, or mathematics. He also mentors several undergraduate students at Rensselaer. <\/p>\n<\/p>\n See original here: Christopher Rivet Is One of Three Finalists for the $30,000 2012 Lemelson-MIT Rensselaer Student Prize Newswise Troy, N.Y.
