Red blood cell has a discoidal shape around 10 μm in diameter and circulates effortlessly through the bloodstream, although the capillaries are as thin as 5 μm. This unique ability is given by their shape, mechanical properties (elasticity, shear thinning) and surface. In this project, we aim to synthesize degradable hydrogel microparticles that mimic these red blood cells properties and thus have in their ability to circulate in the bloodstream for a prolonged period of time (days). These microgels will be used for remote sensing of blood composition.
