What is it about?
This study shows that single‑cell micro‑Raman spectroscopy can discriminate between drug‑sensitive and drug‑resistant multiple myeloma cell lines. Using MM.1S/MM.1R and U266B1/U266‑BTZ‑R pairs, reproducible spectral signatures reveal biomolecular differences. Principal component analysis separates sensitive and resistant cells into distinct clusters using only two components.

Why is it important?
The approach is noninvasive and label‑free, addressing limitations of perturbing or nonspecific methods for identifying neoplastic phenotypes. Distinct Raman peaks linked to DNA/RNA ratio, nucleic acids, lipids, and proteins enable robust discrimination in vitro.
Perspectives
Results are obtained in established cell lines and reflect in vitro conditions. Translation will require validation across broader models and clinical samples, assessment of variability, and integration with standardized analytical pipelines.
