Abstract :
Blood is essential for sustaining living tissue by supplying oxygen and other soluble nutrients to provide stable colloid suspension made of red blood cells, white cells and platelets dispersed in an aqueous solution (plasma) containing a host of biomolecules (fatty acids, hormones, etc). Detection blood type is critical for transfusion as well as many medical procedures. Blood analysis is also important in veterinary medicine. Detection blood typing techniques are available: gel column, thin-layer chromatography (TLC)-immunostaining, spin tube method, fiber optic-microfluidic device, etc. Among those, the identification and automation of red blood cell agglutination by antigen-antibody interaction often requires optical or microfluidic analytical instruments. However, there are no robust and convenient low cost disposable tests available for ”on the spot” analysis of blood type. Blood samples are typically outsourced to an analytical laboratory. Reliable instantaneous test critical blood analysis without requiring sophisticated laboratory analytical instrumentation would be invaluable for improving health in the underprivileged/remote areas of the world.
