    Global Journal of Nanomedicine-Juniper publishers Introduction The nanostructures material with specific properties dependent on their size and geometrical shape has created an interesting research environment for scientist in different fields of application. In particular, noble metals have found applications in optics [ 1 , 2 ], electronic [ 3 , 4 ], biomedicine and antibacterial activity [ 5 - 7 ], and quantum size domain [ 8 ]. ZnO nanostructures, such as ZnO nanoparticles, provide a large surface-area-to-volume ratio and a high fraction of surface atoms [ 9 ], which enhance the antimicrobial activity of ZnO, even at low concentrations [ 10 , 11 ]. ZnO has been generally found to be an n-type semiconductor with a band gap of about 3.3 eV, i.e. absorption begins near the UV A area. ZnO thin films have a great variety of potential applications such as light emitting diodes, laser diodes, solar cells, liquid crystal displays, thin film transistors, and gas s...

    Global Journal of Nanomedicine-Juniper publishers Introduction Nanotechnology is a thriving field with a number of potential applications and is widely used in the fields of medical sciences like drug delivery [ 1 ], bio sensing [ 2 ], and in enhancing antibiotic activity [ 3 ]. In addition to the various applications in the fields of science and technology, an increasing use of nanomaterials has also been reported in biological and medical applications. In particular, Nano pharmaceutics is one of the disciplines that benefit the most from this technology. The importance of metal nanoparticles has been exploited in almost all the fields. Nanomaterials, with their unique size-dependent physical and chemical properties have shown promising advantages as gene delivery vehicles [ 4 , 5 ], ultra-sensitive intracellular detectors [ 6 ] and novel therapeutic drugs [ 7 ]. Increasing multidrug resistance of pathogens is one of the foremost concerns facing the medical...

    Global Journal of Nanomedicine-Juniper publishers Introduction In recent years slow light has attracted a strong interest because of its unique feature to be realized as future on-chip optical networks based buffers [ 1 ] and switching [ 2 ]. Besides of optical buffers, light with reduced group velocity is used to enhance the weak light matter interaction by spatial compressing the optical pulse and increasing the peak intensity [ 3 , 4 ]. Slow light effects can be exploited using variety of techniques, including electromagnetically induced transparency (EIT) [ 5 ] mediums, coherent population oscillation [ 6 ], and optical coupled resonators or photonic crystal waveguides (PCW) [ 7 ]. Photonic crystal waveguide (PCW) provides an efficient means to generate slow light at room temperature and dispersion free propagation over the largest possible bandwidth. The periodic modulation of refractive index greatly affects the optical dispersion relation. Photonic cry...

    Global Journal of Nanomedicine-Juniper publishers Introduction As time goes by, it is incontrovertibility axiomatic that optimization heat transfer in micro-sized devices is a crucial milestone in engineering and industrial applications. It is very important to understand that the fluid flow and heat transfer characteristics in these micro-sized devices have to be optimized in order to gain better designs. One of the most important microscaled systems is microchannel which is used in numerous applications including electronic industry, infrared detectors, integrated circuits boards, laser-diode arrays, insulation design, biological systems, heat exchanger and other compact products with high transient thermal loads. An issue of concern in these devices is the very large heat transfer surface-to-volume proportion in which resulted high compactness and effectiveness of heat removal. So, a deeply understanding of the elaborate micro-scale transport phen...
