Nano delivery systems are a relatively new but rapidly developing science technology where materials in the nanoscale range are used as diagnostic tools or to deliver therapeutic agents to specific targeted sites in a controlled manner. Nanotechnology offers multiple benefits in treating chronic human diseases by site-specific and target-oriented delivery of precise medicines. Currently there are more applications of the nanomedicine includes chemotherapeutic agents, biological agents, immunotherapeutic agents etc. in the treatment of various complex diseases. As nanoparticles comprise materials designed at the molecular level, they are usually small sized nanospheres. It can move more freely in the human body as compared to bigger materials. The use of large sized materials in drug delivery poses major challenges, including in vivo instability, poor bioavailability, and poor solubility, poor absorption in the body, issues with target-specific delivery, and tonic effectiveness, and probable adverse effects of drugs. Therefore, the design of novel advanced drug delivery systems for targeting drugs to specific body parts could be an option that might solve these critical issues.
