The development of advanced therapies and viral vaccines increasingly demands analytical tools that can deliver rapid, precise, and scalable insights into cell health and viral infectivity. Traditional assays often slow, labor‑intensive, and dependent on labels or antibodies struggle to keep pace with modern bioprocessing needs and can delay critical optimization decisions. Laser Force Cytology™, the foundation of LumaCyte’s Radiance® platform, provides a transformative, label‑free alternative capable of real‑time, high‑resolution cellular analysis. By detecting subtle biophysical changes associated with infection and cell state, Radiance® accelerates process development and enhances the efficiency of viral‑based manufacturing workflows.
