Scientists analysed thousands of immune cells from ordinary blood samples without adding dyes; their imaging method identified activated cells with nearly 94% accuracy within 2 hours
Representative Image (AI-generated) A routine blood sample contains a surprisingly detailed record of what the immune system is doing. Scientists have now demonstrated a way to read some of that information without adding fluorescent dyes or other chemical labels. The approach examines the natural light emitted by molecules inside immune cells, allowing researchers to assess…
