Combining the strength of flow cytometry with fluorescence imaging and digital image analysis, imaging flow cytometry is a powerful tool in diverse fields including cancer biology, immunology, drug discovery, microbiology, and metabolic engineering. It enables measurements and statistical analyses of chemical, structural, and morphological phenotypes of numerous living cells to provide systematic insights into biological processes. However, its utility is constrained by its requirement of fluorescent labeling for phenotyping. Here we present label-free chemical imaging flow cytometry to overcome the issue. It builds on a pulse pair-resolved wavelength-switchable Stokes laser for the fastest-to-date multicolor stimulated Raman scattering (SRS) microscopy of fast-flowing cells on a 3D acoustic focusing microfluidic chip, enabling an unprecedented throughput of up to ∼140 cells/s. To show its broad utility, we use the SRS imaging flow cytometry with the aid of deep learning to study the metabolic heterogeneity of microalgal cells and perform marker-free cancer detection in blood.

AbstractThe impact of major nonlinearities in optical fiber such as SRR (Stimulated Raman Scattering) and Four Wave Maxing (FWM) in cascaded amplifier Dense Wavelength Division Multiplexing optical long reach and high speed data rate transmission scheme have been investigated at different data rates. Pulse walk off effect is considered for the purpose of calculating Stimulated Raman Scattering (SRS) nonlinear factor. Examination has been accomplished to assess signal to noise ratio thinking about the consolidated impact of SRS and FWM within the sight of amplified spontaneous emission noise to achieve minutest noise at altered data rates.
