Label-free identification and classification of leukocyte subpopulations in peripheral blood smears by optical photothermal infrared spectroscopy
The differential count of leukocyte subpopulations from peripheral blood smears remains a cornerstone of clinical hematology but relies on staining protocols or flow cytometry, that introduce variability and obscure native biochemistry. This study presents label-free workflows that distinguish leukocytes from erythrocy...
