Polymeric and hyper-branched nanoparticles and dendrimers
Polymeric nanoparticles induced some great advantages in free drugs such as an ability to release the payload in a controlled condition improved bioavailability and making different routes to maintain and carry the drug into the target site. Their synthesis procedures are usually economical and the results require less modifications.
