Dartford and Gravesham NHS Trust has adopted Steriwave nasal photodisinfection for elective orthopaedic surgery, deploying the non-antibiotic technology with Mölnlycke Health Care, Ondine Biomedical said on November 5, 2026. The announcement was published by [Investegate](https://www.investegate.co.uk/announcement/rns/ondine-biomedical-inc-npv-cdi---obi/dartford-and-gravesham-nhs-trust-adopts-steriwave/9859316).

## Dartford and Gravesham's Steriwave Rollout

[Dartford & Gravesham NHS Trust](https://akta.pro/company-profiles/0049jjx/dartford-gravesham-nhs-trust) serves more than 500,000 residents across Dartford, Gravesham, Swanley and the London Borough of Bexley, with Darent Valley Hospital as its main acute site. The trust is adding Steriwave to its surgical infection-prevention pathway to help protect patients from surgical site infections and preserve bed capacity.

[Ondine Biomedical](https://akta.pro/company-profiles/0000gte/ondine-biomedical) is a Canadian life sciences company developing light-activated antimicrobial therapies. Steriwave is a five-minute, clinician-administered treatment that uses a light-activated antimicrobial agent and red light to reduce nasal microbial burden immediately before surgery. The company said the approach reduces reliance on multi-day home-based nasal decolonisation regimens and supports antimicrobial stewardship.

Kris Khambhaita, Director of Infection Prevention and Control at DGT, said: "Introducing Steriwave into our elective orthopaedic pathway is an innovative addition to our wider infection prevention approach, providing a rapid, non-antibiotic intervention immediately before surgery."

Will Ferreira, Deputy Director of Operations for the Surgical Critical & Planned Care Division at DGT, said a trial with Mölnlycke Health Care addressed a planning challenge around MRSA screening and decolonisation before elective surgery. He said patients in this cohort have been treated at the QMH site with treatment organised in less than 24 hours.

Ondine said the deployment follows NHS Supply Chain's classification of Steriwave as an Innovation Product. Leeds Teaching Hospitals NHS Trust recently reported a 78% reduction in surgical site infections in high-risk endoscopic anterior skull-based surgeries in its Steriwave study, according to the announcement.

## Dartford and Gravesham's Hospital Footprint

Dartford and Gravesham NHS Trust operates five facilities, according to akta.pro [company records](https://akta.pro/company-data): Darent Valley Hospital, Queen Mary's Hospital Sidcup, Erith and District Hospital, Gravesham Community Hospital and North Kent Community Diagnostic Centre. The same records place the trust within the Kent and Medway integrated care system, serving the populations of Dartford and Gravesham boroughs and surrounding areas in North Kent.

## Ondine's Earlier 2026 Announcements

Ondine Biomedical requested a temporary suspension of trading for its common shares on AIM from 7:30 am on September 30, 2026, pending an announcement, Investegate reported. On September 7, 2026, Proactiveinvestors reported that Ondine agreed a partnership with Mexico's Hospital Ángeles to pilot Steriwave, following a phase III trial of 5,188 patients showing a 40% reduction in post-surgical infections.
