Nano Flow

Nano Flow, founded in 2015 and based in Leuven, Belgium, is a specialized supplier of high-quality gold nanoparticles and conjugates for the rapid diagnostic test (RDT) industry. As a spin-out of the established diagnostic manufacturer Unisensor, it combines deep expertise in lateral flow assay development with a scalable, ISO-certified production platform. The company's core value proposition is providing consistent, high-performance raw materials that enhance test sensitivity, serving medical, veterinary, environmental, and food safety diagnostics markets. With its products already used in over 150 million tests and a recent capacity expansion, Nano Flow is positioned as a critical European supplier in the growing point-of-care diagnostics sector.

Proprietary automated manufacturing process for highly spherical gold nanoparticles (colloids) and their bioconjugates (e.g., with antibodies). Focuses on controlling sphericity, size distribution, and minimizing aggregation to enhance performance in lateral flow diagnostic tests.

Nano Flow competes with global life science reagent giants (e.g., Cytodiagnostics, BBI Solutions) and chemical suppliers. Its key differentiators are its focus on spherical particle quality, automated scale (positioning it as Europe's largest supplier), direct integration with diagnostic manufacturing expertise from Unisensor, and its European production and support base.
