Easy Shape Control Comes to Drug-Delivery Nanoparticles

Look! Under the microscope! It’s an ellipsoid. It’s a tube. It’s a nonspherical drug-delivery vehicle. More specifically, it’s a perylene-containing polymersome, a nanoparticle with powers and abilities beyond those of normal nanocarriers. Normal nanocarriers are either spherical or capable of one type of nonspherical shape. Pereylene-containing polymersomes, however, can self-assemble into a range of morphologies, depending on parameters as easily controlled as solvent c
