Essay On Nanoparticles - 1066 Words

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 as high sensitivity biomolecular magnetic resonance imaging (MRI) (Bulte et al., 2001), in vivo targeted drug delivery (Sunderland et al., 2006), hyperthermic agents and enhancer in the treatment and diagnosis of cancer (Gupta and Gupta, 2005;†¦show more content†¦Whereas, marine macroalgae have richness in minerals (Wells et al., 2017) that can be used for the greener route synthesis of Fe3O4-MgNPs, and as bionanofactories materials (LewisOscar et al., 2016) have the ability to ac cumulate metals and reduces ions, and could be the superior contender for biosynthesis of metallic NPs (Davis et al., 1998). However, the synthesis of stable Fe3O4-MgNPs using algae extracts are very complicated due to the high reactivity, high particle instability, great propensity of iron ions to oxidization and reduced with a wide array of various chemical compounds, and high tendency to aggregate into agglomerates within the solution (EL-Kassas et al., 2016; Makarov et al., 2014; Huang et al., 2007). In view of inorganic iron oxide nanoecotoxicity, little studies report in the human (mainly inorganic Nano-Fe3O4) (Jeng and Swanson, 2006; Karlsson et al., 2009) and existence the criteria to define the toxicity of nanomaterials does not guarantee that iron oxide nanoparticles pose no potential risks in a challenge with environmental systems and are suitable for use in widespread applications. Hence, due to theirShow MoreRelatedNanoparticles Essay1011 Words   |  5 PagesNanoparticles are materials with overall dimensions less then one hundred nanometers, they are also known as zero-dimensional materials. These particles differ from other nanomaterials because all their dimensions are in nanoscale, apposed to one dimensional or two-dimensional nanomaterials which have one or two dimensions greater then a nanoscale. Nanoparticles have amazing applications in medicine pushing the boundaries of what we can accomplish in areas like medical imaging and drug and gene deliveryRead MoreEss ay On Carbogenic Nanoparticles1511 Words   |  7 PagesTHE AIMS OF THE RESEARCH Carbogenic nanoparticles or as loosely named in literature C-dots ,CDs, CQDs is a new rising star in the class of photo luminescent materials that were reported to be non- toxic and biocompatible. In terms of shape and internal structure they are largely considered to be quasi-spherical Nano- entities with diameter ranging from 3-30 nm. Their elemental content, C-dots characteristically contains a large amount of carbon (at least 44.50%), along with Hydrogen and OxygenRead MoreEngineered Nanoparticles: A Cause for Responsible Innovation Essay916 Words   |  4 Pagesand the increasing incorporation of engineered nanoparticles into consumer products has presented very real health and environmental risks. A growing public debate has arisen weighing the societal induced benefits against the potentially adverse ecotoxicological effects this technology may impose upon humans as well as the surrounding environment. Unfortunately, there remains significant scientiï ¬ c uncertainty re garding the behaviour of nanoparticles. This report attempts to address the possible hazardsRead MoreNanomedicine: A Tiny World Essay2111 Words   |  9 Pagesdiseases and repairing damaged tissues at the molecular level by using nanoparticles. (Appendix 1, Figure 2) Nanowires are one of these materials that can detect illnesses that are found in human body. Scientists are also working on the creation of nanorobots to improve the tools that are used in medical procedures. (Medical Nanobots, Kroeker, 1) However, nano-toxicologists are worried that these new materials which contain nanoparticles could be harmful to humans and the environment. (Nanotechnology DemystifiedRead MoreThe Drug Target And Mechanism Of Action1206 Words   |  5 Pagesunderstand the drug target and mechanism of action of anticancer drugs. The main purpose of this essay is to explain the importance of the various mechanisms of action of cetuximab that ensure selectivity, efficacy and safety of Cetuximab compar ed to 5-FU. First, this essay will provide the history and description of 5-FU, then it will review and analyse its non-selective mechanism of action. Second, this essay will provide the history and description of Cetuximab, after that it will review and analyseRead MoreIs Cancer A Human Body?3657 Words   |  15 Pages They are built in the shape of bacteria. â€Å"They are made of silicon although not entirely mechanical. Part of silicon is the creation of legs instead of the flagella, which is the tail part of the bacteria† (Nanobots the Nemesis of Cancer Biology Essay, n.d). The article also said that they are equipped with a camera that helps doctors see the conditions of the body while the curing process is going on. Nanobots use carbon as the principial element in the form of diamond (Abhilash, 2010). This isRead MoreHumans and Our Culture of Gold Essay1780 Words   |  8 Pagesinherent marvellous glossy shine. Gold is particularly malleable, conducts electricity, d oesn’t blemish and blends well with other metals. Because of these exclusive properties, gold creates its ways into our everyday life in many ways or form. This essay explores the use of gold over time and perception of the cultures that surround by gold. Gold has always had remarkable significance, shown by most civilizations as a symbol of wealth and power. Gold has captivated most of cultures around the worldRead MoreThe Effect Of Food Structure On The Delivery3763 Words   |  16 Pagesnutrients. Moreover, the release of other molecules is also influenced by the food structure. Therefore, it is necessary to develop the food structure through various technologies, such as fluid-bed coating, spray drying, spray chilling, nanoparticles and emulsions. In this essay, two predominate parts will be addressed. The first part is the digestion mechanism and simulated in-vitro digestion models which can use to study the food digestion of humans. The second part is that the manipulation of the structureRead MoreTeaching And Mentoring Experience For Undergraduate Students1312 Words   |  6 Pageswith the focus on an interdisciplinary theme of biophysics and nanoscience.
