Abstract
A method for the ABO and Rhesus (Rh) blood group typing from individual erythrocytes is proposed in this study. Blood-group-specific antibodies immobilized to gold nanoparticles (BG-AuNP) were utilized for the identification of blood groups from individual erythrocytes by objective-type dark-field microscopy (OTDFM). The scattering of free BG-AuNP and their Brownian motion as well as BG-AuNP attached on erythrocytes is easily observed by OTDFM. The strong scattering intensity caused by BG-AuNP packing-enhanced nanoscattering (PENS) on erythrocytes is first demonstrated. PENS combined with OTDFM allows us to identify blood groups within 5 s for all blood group antigens including A, B, D, C, c, E, and e. This was immediately identified by mixing with BG-AuNP without any washing step or waiting for hemoagglutination. Therefore, PENS combined with OTDFM demonstrates feasibility and advantages for use in emergency transfusions where the blood group of patients is unknown. Moreover, matching RhD+ in the case of emergency transfusions may also be beneficial in reducing the shortage of RhD- red blood cell concentrate in the case of a population with a high frequency in RhD-.
