20190170649 · 2019-06-06 · ·

An objective cell is irradiated with laser beam of a predetermined wavelength. Only Stokes light is selected out of detected light including reflected light and scattered light of the laser beam, and a Raman scattering spectrum is obtained by dispersion of the selected Stokes light. A transcriptome of the objective cells is estimated, based on the Raman scattering spectrum. It is preferable to estimate the transcriptome of the objective cells, based on N-dimensional Raman data obtained by dimensional reduction of the Raman scattering spectrum. This configuration only needs to irradiate the objective cell with the laser beam and does not require to destroy the objective cell.

LOCALIZING A SINGULARIZED FLUOROPHORE MOLECULE BY CONTINUOUSLY MOVING A FOCUSED LIGHT BEAM AROUND THE MOLECULE

For determining a molecule position of a singularized fluorophore molecule, a light beam including fluorescence excitation light and fluorescence influencing light is shaped and focused such as to form a light intensity distribution having a central intensity minimum of the fluorescence influencing light. The central intensity minimum is continuously moved along a track repeatedly extending around an estimated position. Individual photons of fluorescence light emitted by the fluorophore molecule due to excitation by the fluorescence excitation light are registered; and an intensity minimum position of the intensity minimum is recorded for the excitation of each individual photon registered. In response, the estimated position around which the track extends is updated on basis of the recorded intensity minimum position, and extensions of the track around the estimated position are reduced and an effectiveness of the fluorescence influencing light is increased.
