Paper Abstract
We report a practical method for label-free quantification of specific molecules using spectroscopic imaging of sampleinduced
phase shifts (for the detail, please see the Ref. [1]). Diffraction phase microscopy equipped with various
wavelengths of light source is used to record wavelength-dependent phase images. We first perform dispersion
measurements on pure solutions of single molecular species present in the cells, such as albumin and hemoglobin (Hb).
With this prior calibration of molecular specific dispersion, we demonstrate the extraction of Hb concentration from
individual red blood cells (RBCs). The end point of this study is
non-invasive monitoring of physiological states of intact
living cells.
