This paper presents hemoglobin measurement based on microfluidic blood cuvettes. Blood sample filled MBC by capillary action, and hemoglobin in the blood sample was measured by absorbance of 530nm-wavelenth light. Microfluidic blood cuvette was fabricated by poly-methylmethacrylate (PMMA) substrate and dry film photoresist (DFR). Two different MBC including dual-side wall and sing-side wall microchannels were designed and fabricated. During blood filling process, air was trapped in microfluidic blood cuvette of dual-side wall microchannel, while there was no air trapping in microfluidic blood cuvettes of single-side wall microchannel. Sensitivity of hemoglobin measurement was more linear in 105(μm-depth microchannel rather than 35(μm-depth microchannel. © 2013 IFMBE.
