The platform

Enamel does not regenerate on its own. Our materials guide new mineral to grow where it has been lost, working with the body's own chemistry.

Our patented platform extends from the tooth into bone and wider tissue repair, built on biomimetic material science with a disciplined path from mechanism to product.

01
Enamel repair

Biomimetic mineralisation that helps teeth heal enamel with the body's own chemistry.

02
Bone regeneration

Protein-derived scaffolds that support bone cells to deposit more mature bone structures.

Applications — 01 · Enamel repair

Regenerative biomaterials, a platform for enamel and bone.

01 — Enamel 02 — Bone

Our first two patent-protected applications and the mechanism each is designed around.

Application 01 — Enamel repair

Enamel, rebuilt at the mineral interface.

Our materials are designed to work with the body's own chemistry to help teeth heal enamel bio-mimetically.

01
Mineral interface

A biomimetic interface designed to bind with native enamel mineral.

02
Guided mineralisation

Ordered mineral growth along the enamel structure to protect and continuously repair damage.

03
Professional integration

Formats developed for delivery within professional & consumer dental care.

The enamel mechanism, in six steps
01Dynamic

Keratin begins as a soluble protein capable of self-assembling into structured architectures.

02Self-assemble

Keratin self-assembles into β-sheet-rich spherulites and fibrous templates.

03Capture + nucleate

The organised keratin structure provides nucleation sites that guide calcium-phosphate mineral growth.

04Grow + organise

Apatite nanocrystals grow from the keratin scaffold into elongated, organised and locally aligned enamel-like mineral architectures.

05Integrate + restore

The repaired enamel recovers its mineral architecture and mechanical properties.

06Retain + protect

The keratin-mediated mineralised layer remains associated with enamel after controlled toothbrushing challenge, demonstrating resistance to abrasion.

Applications — 02 · Bone regeneration

Regenerative biomaterials, a platform for enamel and bone.

01 — Enamel 02 — Bone

Our first two patent-protected applications and the mechanism each is designed around.

Application 02 — Bone regeneration

Scaffolds that let bone rebuild its own architecture.

Bone repair depends on structure as much as chemistry and biology. Our protein-derived scaffolds support bone cells to deposit more mature bone structures compared to current technologies.

01
Structural template

A trabecular-scale scaffold that mirrors native bone architecture.

02
Bone deposition

Our scaffold prevents soft-tissue infiltration to guide bone cells to grow spatially organised bone tissue.

03
Clinical use

For use in orthopaedic and bone grafting applications.

The bone mechanism, in six steps
01Engineer

Keratin self-assembles into tunable membrane architectures with organised micro- and nano-scale structure.

02Hydrate + interact

In aqueous conditions, the keratin surface hydrates and supports stromal-cell attachment, spreading and interaction.

03Protect

The membrane preserves a protected regenerative space while limiting soft-tissue penetration through its thickness.

04Instruct

The keratin environment supports osteogenic signalling and progression toward a bone-forming phenotype.

05Bridge + regenerate

New bone grows inward across the protected defect and progressively bridges the regenerative space.

06Organise + mature

The regenerated tissue develops increasingly organised collagen and lamellar-like bone architecture as healing progresses.
