AI overview

Updated

GreenMark Biomedical is a Michigan dental and medical products company founded in 2016 around a starch nanoparticle platform developed with the University of Michigan. Its sub-micron particles are made from food-grade starch, so enzymes in saliva break them down, which lets them be used as carriers and targeting agents in the mouth. The company sells a caries detection rinse for professional dental exams and a mineral-releasing dental strip, positioning itself around earlier diagnosis and minimally invasive treatment of tooth decay. It operates from East Lansing with lab facilities in Ann Arbor.

What sets it apart

A food-grade starch nanoparticle platform that is enzymatically degraded in saliva, letting the particles both target early-stage carious lesions for detection and carry calcium and phosphate for remineralization — an approach built on detecting and treating decay before drilling rather than restoring it after.

LumiCare Rinse

Dental diagnostic

A caries detection rinse for professional dental use, containing fluorescent sub-micron starch particles functionalized to target and adhere to the subsurface of early-stage carious lesions. Used with a standard dental curing light during an exam, it makes areas of early decay luminesce so the dentist can see the extent of the lesion.

  • Fluorescent sub-micron starch particles that bind to early carious lesions
  • Works with a standard dental curing light and orange filter — no new capital equipment
  • Made from food-grade starch, degraded by enzymes in saliva
  • Sold for chairside professional use, distributed through Dentulu Pro
