Crain's Chicago Business (Jan. 26) -- The state of Illinois is getting back in the venture-capital business for the first time in several years. Treasurer Michael Frerichs says he'll start investing more than $220 million of state treasury money with venture funds across the state. Some of that money ended up with Illinois Ventures, which led a $2.5 million initial investment in Diagnostic Photonics, a Chicago-based medical device company spun out of the U. of I. BioE/ECE professor Stephen Boppart co-founded Diagnostic Photonics, Inc., in 2008, and serves as chief medical officer, assisting in commercializing its optical imaging technology for intraoperative guidance during cancer surgery.
