Аннотация: The Raman spectrum of a single erythrocyte captured by a microfluidic chip was recorded to determine the conformation of hemoglobin under conditions similar to the hemodynamics of a blood vessel. Amplitude changes in the Raman spectrum at 1355, 1375, 1552, 1620, 1585 and 1637 cm−1 reflect changes in pO₂ due to O₂ binding to hemoglobin heme.

Ключевые слова: microfluidics, Raman spectroscopy, RBC, erythrocyte, hemoglobin, conformation.
