Nanotechnology based drug delivery systems for nanomedicine

NanoWerk.com - Tue, 09/18/2018 - 15:31
Development of an effective approach for delivering a new drug is as important as inventing a new drug. Even if a developed new drug has excellent pharmacokinetic and therapeutic properties, it shows its potential activity in the body effectively only when it is exactly targeted to specific molecules. Various nanotechnological approaches for effective drug delivery have been developed and some of them have already been successfully commercialized. Most prominent nano drug delivery systems that are in market place are oncology related and based on liposomal, solid nanoparticle based, protein polymer conjugates and polymer-drug conjugate based delivery platforms.
