Sophisticated technologies are used to discover new drugs, which result in a broad variety of active compounds with high specificity and potency. These drugs need to reach the right place (cell or tissue) in the body, in an adequate concentration and for a specific time period, to have the desired therapeutic effect. Synthetic polymers are used in drug delivery systems such as hydrogels, microspheres/capsules, polymer-coated liposomes, (stent) coatings and nanoparticles. Amphiphilic block copolymers self-assemble into nanoscale morphologies such as micelles, nanoaggregates, nanocapsules, nanogels and polymersomes.
