Abstract
Nanotechnology offers multiple benefits. Nanomedicine and nanodelivery systems are relatively new areas in nanotechnology. There are number of outstanding applications of the nanomedicine in diagnosing diseases, delivering drugs to its target location, and thus treating human diseases. Here materials in the nanoscale range are employed to serve as means of diagnostic tools and also to deliver precise medicines to specific targeted sites in a controlled manner. Also, metal nanoparticles offer great interest in modern chemistry and materials research because of their applications in diverse fields such as photochemistry, nanoelectronics, optics, and catalysis. Chemistry provides various nanostructured materials either synthetic or isolated from natural sources offers opportunities and challenges in drug delivery and their applications including biomedical imaging, biosensing, diagnostic, and therapy. Thymoquinone, a bioactive compound in Nigella sativa, after encapsulation in lipid nanocarrier, has been found to show six-fold increase in bioavailability in comparison to free thymoquinone. In addition to this, organic nanomaterials have recently become of great interest for photovoltaic applications also.
