👉 The Penn Fluid is a synthetic, viscous fluid developed by researchers at the University of Pennsylvania for use in microfluidic devices and lab-on-a-chip technologies. It is designed to mimic the properties of blood, particularly its non-Newtonian behavior, which means its viscosity changes under different shear rates. This fluid is crucial for accurately simulating blood flow in microchannels, enabling researchers to study blood dynamics, clot formation, and the effects of various drugs or medical treatments in a controlled environment. Its unique properties make it an invaluable tool for advancing biomedical research and developing new diagnostic and therapeutic techniques.
