Unisensor S.A.

Unisensor is a Belgian CDMO for rapid diagnostics — development and large-scale manufacturing under one roof.

For more than 25 years we have developed and produced diagnostic solutions for industrial and point-of-care applications, with an annual output of 15 million tests and more than 50 products on the market. Our clients come to us to industrialise an assay they have designed, to secure a European manufacturing source, or to access capacity without investing in their own production lines. Manufacturing is ISO 9001:2015 certified and located entirely at our site near Liège.

Our four areas of expertise:

• Lateral flow immunoassays — high-speed coating, lamination, spotting and cutting lines, with 100% camera-based inspection. Filling and sealing of 96-well microplates, filling, capping, crimping and labelling of 3 mL vials, and lyophilisation on four freeze-dryers (20 m² of shelf area).
• Colloidal gold and conjugation (Nanoflow, a Unisensor brand) — monodisperse gold nanoparticles and bio-conjugates in batches up to 38 L OD10, characterised by TEM, UV-Vis and DLS, with an 18-month shelf life.
• Molecular biology — LAMP PCR assay development from primer design to enzyme selection, bead manufacturing and lyophilisation, in dedicated ISO 6 and Level 2 PCR suites with automated liquid-nitrogen bead freezing (5,000 beads/hour) and storage from 4–8 °C down to −80 °C.
• Instruments and data platforms — lateral flow readers with cloud connectivity and remote management, developed by our in-house design office and FabLab, including hardware, firmware, software and micro/macrofluidics.
