JuniperPublishers-Global Journal of Nanomedicine

  Global Journal of Nanomedicine-Juniper publishers Introduction The development in the field of nanoscience and nanotechnology has opened new avenues for large number of technological applications in the field of biological and biomedical science. The application of nanotechnology in medical applications is comes under "nanomedicine" category which introduces new tools, devices and therapies for treatment of disease. Till date extensive work has been going on the drug delivery, medicine target and used for the treatment of cancer. Due to large surface area to volume ratio of NPs, the loading capacity of therapeutic agents for delivery to target cells and antibacterial activity. By improving UV illumination factors, ZnO particle size, concentration, morphology, and surface modification, powerful antibacterial results would be obtained ZnO NPs exhibit antidiabetic effects also with improved glucose tolerance [ 1 - 10 ]. ZnO is also a biocompatible ma...

Global Journal of Nanomedicine-Juniper publishers Introduction Drug carrier systems (dendrimers, liposomes, polymers, micelles and metal nanoparticles) are promising tools in the treatment of many diseases by providing decreased drug toxicity to healthy cells and tissues and meanwhile increasing the drug bio-availability in targeted cites [ 1 ]. Liposomes are artificially formed vesicles consist of lipids that enclosed as spherical, non- aqueous compartment [ 2 ]. Liposomes have been widely used as a model system of a cell membrane, and more recently have been developed for the controlled release of pharmaceuticals and macromolecules. Liposomes can increase the tolerance of active compounds by lowering the active toxicity of its encapsulated contents, [ 3 ] whilst also opening up the possibility of transporting pharmaceuticals into the tissue of whim in a controlled manner [ 4 ]. After administration to the blood stream, liposomes are mainly taken up in by the liver and spleen [ 5 ] th...

  Global Journal of Nanomedicine-Juniper publishers Introduction Nanomedicine is different from the conventional approaches in sense that conventional medicine's approach is based on a response to problems at a tissue level and by the time that symptoms become apparent to patient or clinician, the disease may be often at an advanced stage. Conventional technology may also rely more on the use of sophisticated and expensive medical tools, machines, robots, minimally invasive devices, and implants. However, in nanomedicine, the goal is to detect changes and problems on the molecular and cellular levels and to treat them before they spread out [ 1 ]. Cancer is the first leading cause of diseased associated death in China [ 2 ] and second leading cause of death in the United States [ 3 ] in recent years. The recent treatment modalities for tumors which mainly include surgery, chemotherapy, radiotherapy, and immunotherapy, among which drug treatment is still most widely used therapeutic...

Global Journal of Nanomedicine-Juniper publishers Introduction Nanotechnology "Nano" means very small or dwarf [ 1 ].Taniguchi coined the term "Nanotechnology" which implies to the modification, reduction and fabrication of materials at nano scale with distinctive properties such as good strength, cost effective, lighter, eco friendly, definite and specific etc [ 2 , 3 ]. Even though nanotechnology is at its early stages, but is growing fast, opening numerous prospects for the scientific minds to use this enhanced technology for human welfare [ 4 - 6 ]. Nanoparticles Nanoparticles are nano-sized objects whose size is measured in nanometers (nm) ranging from 0.1nm-100nm [ 7 ] exhibiting distinct morphological characteristics which is quite different from their bulk form. Biosynthetic methods for nanoparticles synthesis Although atomizer technologies, photochemical reduction, laser ablation, ultrasonic fields,lithography,ultraviolet irradiation techniques have been co...
