GreenMark Secures $1.2M Seed Funding to Advance Nanoparticle-Based Minimally Invasive Dental Therapy

VCBeat (WeChat ID: vcbeat) recently learned that U.S. biopharmaceutical company GreenMark has completed a $1.2 million seed financing round to further develop and commercialize its nanoparticle-based dental technology. The round was led by Blue Water Angels, with participation from Invest Detroit Ventures and the University of Michigan’s BRCC.

Headquartered in Michigan and founded in 2016, GreenMark is collaborating with the University of Michigan to develop food-grade starch-based nanoparticles. These particles serve as ideal carriers for medical and dental applications, enabling non-invasive treatment of early-stage tooth “cavities” associated with caries formation.

GreenMark’s products will be used by dental professionals for routine examinations. These starch particles, labeled with fluorescent markers and loaded with minerals depleted due to tooth decay, are illuminated using standard curing lights found in dental clinics, thereby reducing patient discomfort and improving long-term oral health. The nanoparticles degrade into harmless components once patients leave the dental clinic.

“We are delighted to invest in GreenMark, a company with close ties to the University of Michigan,” said Rafael Castilla, Investment Director at Blue Water Angels. “We are optimistic about the potential of the company’s technology and its expert team spanning medicine, biomaterials, manufacturing, and finance.”

“These targeted diagnostic and therapeutic products can cure cavities in their early stages through non-surgical treatment, thereby reducing the need for costly invasive dental procedures,” said Charlie Moret, Chairman and CEO of BRCC.

In addition to investor capital, GreenMark has secured funding through multiple channels, including two loans from the MCRN Small Business Innovation Research (SBIR) program, a business accelerator fund grant provided by the Michigan Small Business Development Corporation, and grants from the National Institutes of Health (NIH). The company’s dental diagnostic products have received official certification from the National Institute of Dental and Craniofacial Research (NIDCR).

Blue Water Angels was established in 2008 and serves more than 50 high-net-worth individual and institutional clients. The firm’s mission is to pool client capital to invest in promising startups, thereby fostering economic development and job creation. To date, Blue Water Angels has cumulatively invested over $18 million.

Located at Western Michigan University, the BRCC was established in 2003 as a non-profit investor with a $10 million special appropriation from the Michigan State Legislature. The organization aims to provide seed funding to early-stage companies in the life sciences sector, including areas such as biotech therapeutics, diagnostics, and medical devices. The BRCC also provides financial support to certain contract research organizations (CROs) and contract manufacturing organizations (CMOs).
