Abstract:
1. A method of determining a rate of cell reproduction using a laser biocavity including a semiconductor laser, comprising: a) determining a laser wavelength of a laser biocavity; b) determining a wavelength shift of the laser wavelength of the laser biocavity when a cell in a fluid passes through a microchannel of the laser biocavity; c) categorizing a phase of the cell by comparing the wavelength shift of the laser wavelength of the laser biocavity to a wavelength shift generated by a G2 phase call of the same type as the cell in the fluid to determine whether the cell is in a G2 phase; d) determining the phase of a plurality of cells by repeating steps b and c; and e) determining a percentage of the plurality of cells in a G2 phase as an indication of the rate of cell reproduction.
