In this study, Brillouin spectroscopy was employed to investigate the viscoelastic properties of melanoma cells in vitro. Using a custom-built confocal Brillouin microspectrometer, we obtained Brillouin shifts and full width at half maximum (FWHM) values, enabling the non-invasive assessment of cellular stiffness and viscosity. The Brillouin spectra revealed the biomechanical characteristics of melanoma cells, with measured shifts and FWHM values providing a detailed viscoelastic profile. These findings demonstrate the capability of Brillouin microscopy to probe the mechanical properties of cancer cells at the subcellular level. This technique holds significant potential for advancing cancer research by providing insights into the mechanical behavior of melanoma cells, which could inform the development of diagnostic tools and therapeutic strategies based on cellular biomechanics.
