A nanoparticle (or nanopowder or nanocluster or nanocrystal) is a microscopic particle with at least one dimension less than 100 nm. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields. Nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic or molecular structures. A bulk material should have constant physical properties regardless of its size, but at the nano-scale this is often not the case. Size-dependent properties are observed such as quantum confinement in semiconductor particles, surface plasmon resonance in some metal particles and superparamagnetism in magnetic materials. The properties of materials change as their size approaches the nanoscale and as the percentage of atoms at the surface of a material becomes significant. For bulk materials larger than one micrometre the percentage of atoms at the surface is minuscule relative to the total number of atoms of the material.
Open Access should be seen as a means of accelerating scientific discovery by providing free and unrestricted access of scientific knowledge via the Internet. An essential role of Open Access is the long-term preservation of peer-reviewed scholarly journal articles and research data. An Open Access publishing group focuses on to encourage innovation, socio-economic development, and flow of knowledge around the world. One such, Open Access is OMICS which is committed ultimately for public welfare to stimulate the growth of global science, as well as maintain the quality of scientific achievements at the same time. Bio crimes related articles are published in rice research open access journal , this journal publishes quality manuscripts which has good impact on the society .
