In vitro evaluation demonstrates label-free tracking of cancer cell death in tumor cells, highlighting its potential for rapid screening of drug effects.
We present a compact and portable stimulated Raman scattering (SRS) imaging system capable of high speed, label-free imaging of cells and tissues. Our setup rapidly acquires multispectral datasets with high chemical specificity by scanning the spectral range of 700-3100 1/cm in just 100 ms, providing a tenfold increase in acquisition speed. It allowed to visualize cell nucleus and cytoplasm changes during drug induced cancer cell death. SRS offers distinct advantages, providing valuable insights into drug-cell interactions, cell morphology, and chemical changes without the interference of exogenous labels. The novel high-speed SRS systems allows rapid screening of drug effects on cancer cells.
