Changing bacteria for the better

Bioaction innovative gene-loaded bio-hydrogels convert harmful bacteria into a programmable bio-factory for tissue regeneration, turning a clinical threat into a potential opportunity for patient benefit

The components of the bio-hydrogels

Genetic sequences

Designed to encode proteins necessary for tissue regeneration and to regulate immune responses.

A safety circuit is also included to control bacterial proliferation and prevent uncontrolled growth in the host.

Sequence carriers

Designed to encode proteins necessary for tissue regeneration and to regulate immune responses.

  • Liposomes: small spherical vesicles composed of lipid bilayers
  • Phages: viruses that infect bacteria

These carriers can inject genetic material into bacteria.


The carriers are incorporated into the surface of bio-hydrogels that can be used as a coating for implants or as injectable material formulations for infection sites.

Turning infections into allies

When applied to infection sites, the hydrogel carriers interact with local bacteria and inject the genetic material. These genetic sequences are incorporated into bacterial chromosomes, transforming the bacteria into a source for producing beneficial proteins.

Application of bio-hydrogel on infection site
Reprogramming of biofilm via bio-hydrogel
Production of pro-regenerative proteins

Addressing three key aspects of implant infections

  1. Reprogramming biofilm molecular physiology
  2. Regeneration
  3. Guidance

The gene-loaded hydrogels stimulate the production of proteins necessary for tissue regeneration and promote bone growth, ultimately accelerating the healing process.

Additionally, the hydrogels improve device integration in the implantation site and guide the spatio-temporal complex multicellular tissue regeneration process.

The bio-hydrogels exposing carriers on their surface loaded with genetic sequences will be validated in vitro and in vivo for therapeutic efficacy and biosafety. The in vivo studies are consistent with dental and orthopedic clinical applications using two animal models with different implant/infection sites.
