"Nano-Velcro" Wins at Bioscience Day

Department of Chemical and Biomolecular associate professor Srinivasa Raghavan and his advisee, Fischell Fellow and bioengineering graduate student Matt Dowling, won the attention of a group of venture capitalists and the title of "Best Inventor Pitch for Bioscience Day 2008" for their presentation of "nano-velcro", a biomaterial they invented capable of stopping bleeding, particularly in situations where surgical help is not immediately available.

Sponsored by the university's Office of Technology Commercialization, the College of Chemical and Life Sciences, and the A James Clark School of Engineering's Maryland Technology Enterprise Institute (MTECH), the second annual "Professor Venture Fair"—part of the University of Maryland’s annual Bioscience Research & Technology Review Day—gave faculty and inventors the opportunity to pitch their new technologies to a team of five venture capitalists and entrepreneurs from the region. Presenters were judged based upon clarity of pitch and commercial viability.

"Dowling [in his pitch] addressed all of the questions that needed to be answered for the judges to determine that there is a real market opportunity here," says Jim Chung, director of MTECH's VentureAccelerator Program.

Dowling and Raghavan's nano-velcro is a new, patent-pending biomaterial they are developing into two products: a sponge that is applied directly to a wound to stop hemorrhaging, and a spray that halts blood loss and seals tissue in a variety of situations, from minor surgical bleeding to life-threatening arterial punctures. Both products can be gently removed after wounds heal. Pre-clinical testing is underway for both the sponge and spray.

Dowling, Raghavan and their colleagues create nano-velcro by attaching fatty grafts to the biopolymer chitosan, which is derived from the shells of crustaceans such as crabs and shrimp. The fatty grafts gently hook onto blood or soft tissue, similar to Velcro®, enabling the chitosan to act directly and more effectively in blood coagulation and wound healing.

"More than anything, this award validates excitement about our technology from investors," says Dowling. "We're very confident in our technology, but selling it is a separate and distinct challenge. Today was a good indication that venture capitalists are starting to buy into what we're selling."

Dowling launched Remedium Technologies Inc. in 2007 to bring the invention to market. The company took second place in the 2007 University of Maryland $50K Business Plan Competition graduate student category, winning $8,000. Remedium has since won the University of Nebraska Business Plan Competition and participated in both the Rice Business Plan Competition and the Moot Corp Competition held by the University of Texas at Austin. In August 2008, Remedium received a $103,950 Maryland Industrial Partnerships project award to further develop its technology.

The nano-velcro research was also covered by Baltimore CBS affiliate WJZ-TV.

Remedium's other present and founding members include Fischell Department of Bioengineering graduate student Peter Thomas, chemical and biomolecular engineering alumna and research associate Oluwatosin Ogunsola (Ph.D. '05, chemical engineering), alumnus Bani H. Cipriano (Ph.D. '07, chemical engineering), and former ChBE research associate Chao Zhu, all of who are or were advised by Raghavan.

Judges for the Best Inventor Pitch included: bio-entrepreneur Lou Cantolupo; Christine Copple, president and CEO of Starise Ventures Inc.; Mark Grovic, general partner of New Markets Venture Partners; Bruce Robertson, managing director of H.I.G. Ventures; and Matt Zuga, managing director of Red Abbey Venture Partners.

"This event, along with the information technology Professor Venture Fair at the Institute for Systems Research Symposium in the spring, offer the best window into the most promising science and technology innovations and potential startups coming out of the University of Maryland," says Dean Chang, director of MTECH's venture creation and entrepreneurship education programs. "Since we started these Professor Venture Fairs just over a year ago, all three winners of the Best Inventor Pitch have gone on to form exciting companies, which says as much about the growing entrepreneurial culture here on campus as it does about the quality of these inventions."
