In recent years, quantum Fourier transform infrared (QFTIR) spectroscopy has emerged as an alternative to conventional absorption in the mid-infrared region of spectrum. By harnessing induced coherence and spectral correlations photon pairs a nonlinear Michelson interferometer, this technique offers promising potential for practical detection organic gases. However, little research was conducted bring QFTIR spectrometers closer domestic or in-field usage. work, we present first use...

Abstract The pre‐clinical validation of cell therapies requires monitoring the biodistribution transplanted cells in tissues host organisms. Real‐time detection these circulatory system and identification their aggregation state is a crucial piece information, but necessitates deep penetration fast imaging with high selectivity, subcellular resolution, throughput. In this study, multiphoton‐based in‐flow human stem whole, unfiltered blood demonstrated microfluidic channel. approach relies on...
