Nanoparticles Nanoparticles are defined as the microscopic particles with at least one dimension less than 100 nm. Nanoparticles are of immense scientific interest because of their vast potential applications in biomedicines, computer, electronics, and defense industries. Nanoparticles are of great scientific and technological interests because they can effectively act as bridge between the bulk form and atomic or molecular structures of the materials. Bulk materials possess constant physical and
distribution and fate of the nanoparticles that is released into the environment. Properties of nanoparticles can impact the environment in a negative way. The surface effects of nanoparticles are both favourable and unfavourable. When they are exposed to tissues or cell of the body they get adsorbed on to their surface, thus they are highly used in medicine field for drug delivery use (Nowack & Bucheli, 2007). By crossing cell membrane or entering the blood stream, the nanoparticles may target other organs
Thus, CHPs−AuNPs were revealed as the ideal applicant for the treating cancer cells and other biomedical application. 1. Introduction The nano-biotechnology research field shown fast growth over the past decades, utilizing gold nanoparticles (AuNPs) in biological applications, due to their unique surface, optical and electronic properties [1,2]. Thus, new research in nano-synthesis, design, and functionalization of AuNPs have to, improve their efficiency, bio-compatibility, and find
activity with distinct crystallography that increases the surface area (Sinha et al., 2009). Thus in recent years much research is going on metallic nanoparticle and its properties like catalyst, sensing to optics, antibacterial activity, data storage capacity and its use in agricultural productivity (Nair et al., 2010 & Sharma et al., 2009). Nanoparticles can be synthesized using various approaches including chemical, physical and biological. Although
Nanoparticles are so small in size that they can enter cells and organelles to interact with DNA, proteins, enzymes while circulating throughout the body. Therefore, nanotechnology is used in detecting disease in a very small volume of cells or tissue [1].As mention above; commonly used nanoparticles are such as, gold nanoparticle, silver nanoparticle, quantum dots and magnetic nanoparticle. Gold nanoparticles have unique stability against oxidation which makes it useful in diagnostic. Its benefits
For 8 weeks of vacation work I have been looking at preparing and characterizing nanoparticulate systems to encapsulate the antimicrobial drug mupirocin. Specifically polymeric nanoparticles and liposomes were investigated. Chronic Rhinosinusitis (CRS) is an inflammatory disease of the nasal mucosa; often resulting from a Staphylococcus aureus (S. aureus), a bacterial infection in the sinus cavity (Suh JD. & Kennedy DW., 2011). S. aureus can be treated with antimicrobial mupiriocin (MUP). Nasal

application of nanotechnology. For example, DNA nanotechnology or cellular engineering would be classified as bionanotechnology because they involve working with biomolecules on the nanoscale. Conversely, many new medical technologies involving nanoparticles as delivery systems or as sensors would be examples of nanobiotechnology since they involve using nanotechnology to advance the goals of biology. Objectives of Nanobiotechnology: • The most important objectives that are frequently found in nanobiology
Nano technology in dentistry - review article. Introduction Nano-technology is a revolution in almost all disciplines of life today. Nanotechnology approaches the manipulation of matter at atomic and molecular level. This technology, which deals with matter in nano-dimensions, has widened our views of poorly understood health issues and provided novel means of diagnosis and treatment. Dentistry, not being an exception, also faces major revolutions to constantly provide better and more comfortable

objects whose size is on the nanometer scale (1-100nm) Nanoscience is the study of metal nanoparticles (Banerjee et al, pp. 42) ,and these particles are widely distributed in nature. These particles may be form when volcanic eruptions spew out materials from below the earth surface or when tidal waves erode a coast or bank. The notorious eruptions of Eyjafjallajokull spread in the atmosphere nanoparticles of size range 100-400nm (Harrison et al, 2010). Nanotechnology: Nanotechnology is the engineering

Synthesis of metal nanoparticles has become increasingly important in science and engineering. Being able to control the processes is vital to success in applications and uncovering the mechanisms of nanoparticle production. Nanowires are one of the varieties of nanoparticles that will be utilized for this project. There

When she is not working on reviewing the nanotechnology program, Huo is doing her own research in nanoscience. She recently published a paper on gold nanoparticles being used in cancer detection. “The bottom line is that we want our students to become competitive,” said Dr. Huo. The program was designed to give undergraduate students the chance to continue their education and have a chance to get valuable
Nanoparticles are defined as particulate materials with at least one dimension of less than 100 nanometers (nm), even the particles could be zero dimension in the case of quantum dots (Bar et al., 2009). Metal nanoparticles have been of great interest due to their distinctive features such as catalytic, optical, magnetic and electrical properties (Rassaei et al., 2008). Nanoparticles present a high surface area to volume ratio with decrease in the size of the particles. Specific surface area
Nanotechnology is the study of extremely small things and is used in the fields of chemistry, biology, physics, materials science, and engineering. Nanotechnology is measured on what is called a nanoscale, also known as a nanometer which is one billionth of a meter. The important 3 steps of nanotechnology are “small size, measured in 100s of nanometers or less, unique properties because of the small size, and control the structure and composition on the nm scale in order to control the properties
