ChromaTwist

ChromaTwist is a UK-based private company and University of Birmingham spinout developing large Stokes shift organic fluorescent dyes and fluorophores for bio-imaging and bio-sensing applications. Its platform uses patented, modular, and scalable chemistry to create UV- and blue-excited probes with tunable emission across the visible spectrum. The company focuses on research-use and diagnostic-enabling applications including flow cytometry, multiphoton microscopy, and related imaging workflows rather than therapeutic drug development. ChromaTwist also sells chemical precursors and fluorescent materials and has established a supply agreement with Merck (Sigma-Aldrich) for distribution of certain dyes. Overall, it is best characterized as a life science tools and advanced materials company serving biomedical research and diagnostics markets.
