Abstract

As biochemical, pharmaceutical, and medical sciences advance, the demand for technologies capable of probing multiple cellular targets simultaneously continues to increase. Super-multiplexed spectroscopic techniques offer a pathway toward comprehensive cellular fingerprinting by overcoming the spectral limitations of conventional fluorescence labeling. By circumventing the traditional “color barrier,” cyanine-based Raman tags enable the simultaneous discrimination of numerous cellular morphologies, allowing spectroscopy and imaging to be integrated for high-dimensional cellular analysis. Technologies developed in Goda Lab—including high-throughput flow cytometry, virtual freezing fluorescence imaging (VIFFI), Fourier-transform coherent anti-Stokes Raman spectroscopy (FT-CARS), and MERdot nanoparticles—address longstanding trade-offs between throughput, resolution, sensitivity, and multiplexing capacity. Central to these advances are cyanine dyes, whose structural tunability enables the creation of expansive, spectrally distinct color palettes required for super-multiplexed applications. Beyond their role in Raman-based cellular fingerprinting, cyanine dyes exhibit favorable photostability, biocompatibility, and photophysical adaptability, supporting applications in surgical imaging, live-cell analysis, cancer diagnostics, and dye-sensitized solar technologies. Collectively, these properties position cyanines as strong candidates for next-generation fluorophores in multiplexed spectroscopy and biomedical imaging.
