Stream Bio

Stream Bio is a developer and manufacturer of fluorescent conjugated polymer nanoparticles for biological imaging and diagnostic research.

Its visible and near-infrared probes support microscopy, flow cytometry, immunoassays and lateral-flow test development. The company supplies streptavidin-linked reagents and conjugation kits for attaching antibodies or oligonucleotides to nanoparticles, alongside bespoke labelling services.

The technology originated from King's College London research and offers alternatives to conventional fluorescent dyes and quantum dots.
