The financing arm of the S.C. Research Authority has invested $200,000 in a Charleston-based bioengineering firm.

First String Research, which is developing a wound treatment that speeds the healing process while reducing scar tissue, is to receive the funding today from SC Launch at the Charleston Metro Chamber of Commerce's Small Business Innovation Summit & Expo at Trident Technical College.

Gautam Ghatnekar, First String's president and chief executive officer, said the SC Launch capital and other recent funding sources has enabled the company to double in size over the past six months.

The three-year-old company's business model is based on research from the Medical University of South Carolina.
