Polymerix Technologies
Advancing Polymer Science for Medical Devices and Commercial Applications
Boston, MA · Founded 2020
Who We Are
Polymerix Technologies is a Boston-based startup founded in 2020 by Dr. Anuj Bellare and Dr. Bruce Carvalho — two scientists and engineers with deep roots in polymer science, biomedical materials, and medical device development. Our company is focused on translating cutting-edge polymer chemistry into real-world products that improve patient outcomes and extend the performance of industrial materials.
Our company brings together decades of academic research and industry experience to develop novel crosslinking and antioxidant technologies based on diazirine chemistry — a platform with transformative potential across medical implants, tissue engineering, packaging, and beyond.
What We Do
Polymerix has developed a proprietary family of diazirine-based compounds — small molecules that, when activated by heat or UV light, form permanent chemical bonds with virtually any material containing C–H, N–H, or O–H groups.
Crosslink Polymers
Our diazirine crosslinkers bond directly to polymer chains and release only nitrogen gas — no toxic residues to remove. Ideal for UHMWPE used in joint replacement prostheses.
Non-leaching Antioxidants
Antioxidant-diazirine compounds chemically graft onto polymers, tissues, and device surfaces — eliminating the leaching risk of conventional additives.
Bond Dissimilar Materials
Multifunctional diazirine compounds act as molecular glues, bonding UHMWPE to metals, ceramics, bone cement, or tissue for implant fixation and composites.
Broad Applicability
The same chemistry works across synthetic polymers, biological macromolecules, tissues, and industrial surfaces — from medical implants to aerospace composites.
Our Focus Areas
- Orthopedic Implants — Chemically crosslinked UHMWPE components for total joint replacement with superior wear resistance, mechanical integrity, and oxidative stability. Supported by NIH SBIR funding.
- Medical Device Coatings — Non-leachable antioxidant surface treatments for long-term implantable devices including spinal implants, hernia meshes, stents, and airway devices.
- Tissue Engineering & Regenerative Medicine — Diazirine-based crosslinkers and antioxidants for collagen and synthetic hydrogel scaffolds used in cartilage, bone, ligament, and soft tissue repair.
- Industrial Polymers — Diazirine crosslinkers and antioxidant additives for packaging, fuels, lubricants, and fiber-reinforced composites in aerospace, automotive, and construction.
Our Founders
Anuj Bellare, PhD
Co-founder & President
PhD in Chemical Engineering (Polymer Science) from MIT; postdoctoral training at Princeton. Former faculty at Harvard Medical School and Director of the Orthopedic Nanotechnology Laboratory at Brigham & Women's Hospital, where his research focused on crosslinked UHMWPE and bone cement for joint replacements. Named inventor on multiple patents with extensive publications on polyethylene wear, fracture toughness, and antioxidant stabilization.
