Essay on Nanotechnology

Nanotechnology Nanotechnology is actually a fairly new idea. This may not seem like any big deal in terms of ethics, but just like any type of scientific advancement there are positives and negatives. Of course the ethical issues don't stem out of just the fact that this is a new kind of science. It branches off of "what will this new scientific technology be used for?" For example, Embryonic Stem Cell research. It's not the research that's bad it's how they get the cells. There are half

us of fungi to support large scale production of acids, biosurfactants and enzymes. In the 1980’s, with the dawn of fresh nanotechnology, fungi had remained important by being able to synthesize nanoparticles. Nanoparticles or nanomaterials are materials including particles or constituents that are of nanoscale proportions, or something that has been produced via nanotechnology. Biologically hazardous or environmentally toxic reducing agents are normally associated in the nanoparticles chemical synthesis

with an antibody to target a specific biomarker. Due to the nature of nanoparticles and their small sizes, nanoparticles can be taken in by cells where larger particles would be excluded or cleared from the body. One way to deliver a drug using nanotechnology is engineering a nanoparticle so that it carries the pharmaceutical agent inside its core, while its shell is functionalized with a binding agent specific to a biomarker. A schematic of this mechanism is shown in Figure 1 (Nie S., et al 2007)

Introduction Nanotechnology is the study of particles on the nanoscale with, at least one dimension being less than 100nm. (Chen, Schluesener, 2008) Nanoscale particles can come in many shapes and sizes, ranging from 100 - 1 nm. These particles can be found as rods, cones, spheres and many more complex matrices and patterns as seen in figure 1.(Champion, Katare, Mitragotri, 2007) Nanosilver will form a roughly spherical shape as can be seen in figure 2. (Utopia Silver Supplements, 2012) In the medical

In the seventh semester, I filled all three elective slots with courses allowing me to follow up on my resolution; BIO-MEMS (Micro Electronic and Mechanical Systems), Miniature Microwave Circuits and Material Science for Micro and Nanotechnology electives. #This para has to be changed for Washington univ (No vhsm reco.)# It was my good fortune, to have found an excellent mentor in Dr. VHS Moorthy, who taught me both MEMS and

In recent years, inorganic and chemosynthesized superparamagnetic iron oxide nanoparticles (SIONPs) such as Fe3O4 magnetic nanoparticles (Fe3O4 MgNPs) have attracted extensive interest for their biocompatible (Kunzmann et al., 2011) and low toxic properties mainly in the human body studied (Jeng and Swanson, 2006; Karlsson et al., 2009) which make them as promising remedial tools in related fields. Magnetite nanoparticles is the most-studied for many technological applications in biomedicine, such

Mirkin has published on a variety of nanotechnology applications, including; anisotropic nanostructures, programmable nanostructure, dip-pen nanolithography, and spherical nucleic acids. The general goal of his research is to develop analytical technique, bio-diagnostic, and biotherapies that are assisted by nanoparticles. The primary focus of this report will be Professor Mirkin’s work on bio-therapeutics performed with spherical nucleic acids (SNA’s). A SNA can be defined as a nanoparticle bound

Research Statement As a Research Associate (and a former Research Fellow) at the Harvard T. H. Chan School of Public Health (HSPH), my research has focused on i) the development of novel platforms to investigate exposure to particulate matter (Coarse, Fine, and Ultrafine Particles) and gaseous pollutants and ii) to understand the exposure risk, pathways, dose, and health effects. To attain these goals, I implemented state-of-the-art analytical techniques to characterize the exposures, developed novel

In the ever-advancing field of nanotechnology and materials science there has been a buzz in the air in recent years over Gold Nanorods (GNRs). Their unique structure and ease of synthesis provides a range of optical properties that can be readily manipulated. These properties can be utilised in various applications such as surface functionalisation, photothermal therapy to manage tumours and cancer cells. In this review, we will look at the current research that analyses the toxicity of GNRs and
