Current technologies for blood oxygen measurement, however, do not possess high spatial resolution and therefore cannot be used to detect small tumors in their early stage. In this paper, we studied the third harmonic generation (THG) spectra of oxy-and deoxyhemoglobin in the 1170-1365 nm region, which is strongly influenced by the multi-photon resonance effect, especially around the Soret transition band. Our spectroscopic results thus indicate the high potential of THG spectroscopic microscopy for oxygen depletion level measurement of a single red blood cell in vivo. ? 2010 by WILEY-VCH Verlag GmbH & Co.
