Nanoarchitectonics has gained remarkable importance due to the fabrication of various recent nanostructures with the capability of being used in biomedical science, particularly in cancer diagnosis and treatment. These nanosized structures possess unique physical and optical properties that can be exploited for cancer therapeutics, and so nanoarchitectonics is popularly known as nanomedicine. The goal of this review is to discuss the latest findings in nanostructures research including nanocrystals, nanotubes, nanoshells, nanopillars, nanoballs, nanoflowers, nanorods, nanocontainers, nanobelts, nanocages, nanodiscs, nanodots, nanoprisms, nanoplates, nanorings, nanocubes, nanobranches, nanospheres, nanorattles, nanostars, nanotrees, nanowires, nanowalls, nanodiamonds, nanosheets, layered nanostructures, quantum dots, mesoporous nanostructures etc. in the field of cancer therapy and imaging. This review further highlights brief information about use of radionuclide in cancer. Lastly, different nanoformulations that are available in the market or are under clinical trials for cancer therapy and imaging are discussed.

A simple, specific, accurate and precise reversed phase high pressure liquid chromatography (RP-HPLC) method has been developed for the simultaneous estimation of tramadol hydrochloride (TRA) and dicyclomine (DCY) in bulk and tablet dosage form. Chromatography was carried on Phenomex Gemini C 18 column (4.6 x 250 mm, 5µ particle size) using mixture of methanol, acetonitrile and 0.1% triethylamine (TEA) pH 3.0 (adjusted with orthophophoric acid) in the ratio of 35:5:60 (v/v/v) respectively as a mobile phase. The flow rate 1.0mL min -1 and detection wavelength 275 nm was selected for the present study. The retention time of tramadol hydrochloride and dicyclomine were 4.13 min and 9.06 min respectively. The linear regression analysis data for the calibration plots showed a good linear relationship over the concentration range of 50-300 μg mL -1 for tramadol hydrochloride and 10-60μg mL -1 for dicyclomine. The proposed method was validated with respect to linearity, precision, accuracy, specificity and robustness. The proposed method was found to be simple, rapid, accurate, precise and reproducible. Thus it can be applied for routine quality control analysis of tramadol hydrochloride and dicyclomine in tablet dosage form.
