Abstract
For decades, researchers have tried to develop non-invasive mechanisms for monitoring pathological conditions within the body of patients. Emerging nanotechnology enabled us to reach this aim. Scale of nano has the potential to increase early detection of pathological conditions among abnormal cells before diseased tissue or tumor development can be considerable which is helpful in disease treatment. In recent years, “Theranostics” has been emerged as a novel nano approach which performs diagnostic detection, therapy and follows up simultaneously. Therefore, Theranostics can be considered as an appropriate therapeutic approach for personalized medicine, pharmacogenomics and molecular imaging which can open a gate to develop novel therapies. Additionally, with a deeper molecular understanding, choosing drugs that are more effective will be possible. Finally, researchers believe that Theranostics has the potential to monitor treatments by increasing drug effectiveness and preventing inappropriate treatments and consequently reducing the cost of national health burden. In this review, structure and some applications of Theranostics and nano drug delivery systems have been discussed briefly.

Abstract
Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubility and bioavailability of poorly water-soluble drugs. The self-nanoemulsifying drug delivery system is an ideal method for improving the solubility and bioavailability of poorly water-soluble drugs. This system is a sustainable combination of drugs, oils, surfactants, and cosurfactants. The combination of these components causes the nanoemulsion of oil in water with the size of droplets in the range of nm, thereby increasing the bioavailability and oral absorption of poorly water-soluble drugs. This system is highly regarded for its benefits and the ability to improve the healing properties of oral medications.
