Products
Dragonfly (portable multi‑pathogen molecular diagnostic platform)
Handheld molecular diagnostic reader and single‑use test panels for simultaneous detection and differentiation of multiple viral and other pathogen targets at the point of need; uses rapid extraction and isothermal colourimetric detection.
SmartLid nucleic acid extraction kits and accessories
Bead‑based extraction kit using a magnetic lid/key system, sold as starter and refill kits; includes magnetic beads, buffers, reusable magnetic keys, SmartLids, shaker and rack accessories.
TurboBeads (high‑magnetism magnetic beads)
Pure metal core magnetic beads with covalent surface functionality, designed for fast magnetic separation across volumes and compatibility with a wide pH range and solvents.
LyoLAMP (lyophilised colourimetric LAMP reagents)
Ambient‑stable, lyophilised LAMP reagent beads with colourimetric readout designed for ease of use and deployment outside cold‑chain environments; available in multiple formats and customisable panels.
Lacewing (diagnostic platform in development)
In‑development diagnostic approach intended to assess patient immune response to distinguish bacterial vs viral infections and estimate severity for rapid clinical triage; currently in development and supported by targeted funding.

News & Updates
Independent point‑of‑care service evaluation reported high diagnostic accuracy, usability, portability and ease of adoption for a multi‑pathogen respiratory test (reported sensitivity 98.4% and specificity 100% vs RT‑PCR for five pathogens).
Awarded SBRI Healthcare funding to accelerate development of a portable diagnostic intended to identify bacterial versus viral infections and assess severity to address antimicrobial resistance.
Field evaluation across community finger‑prick samples in The Gambia and Burkina Faso reported high sensitivity (95.2%) and specificity (96.8%) for a malaria species panel; results noted as published in Nature Communications.
Regulatory conformity achieved for a rapid multi‑viral respiratory test panel enabling availability in EU/UK markets.
