Nanoparticle

The use of nanotechnology can provide a specific drug delivery system and overcome the challenges faced. Nanotechnology is a field that covers various areas such as biology, engineering, chemistry and physics (Gandhi et al., 2014). Due to its small size, nanoparticles have high surface area that not only allow ways for more efficient drug release to the cells and also be able to be functionalization (Nie et al., 2007). There are mainly…

3.1. Green photosynthesis of gold nanoparticles using aqueous extract of Baker’s yeast: One aim of the present study is the development of an improved method for derivatization of metabolites existed in aqueous extract of Baker’s yeast (Saccharomyces cerevisiae). This procedure facilitates identification of metabolites in Baker’s yeast extract and its utility for the synthesis of nanomaterials. The preparation of trimethylsilylenol ethers of metabolites was performed by treatment of the extract…

PART 2 Article 1: Researchers disguise drugs as platelets to target cancer 1) Describe the structure of the nanoparticle, including what it is composed of and what it contains inside and possesses on the outside. Inside there is a synthetic core nanogel. On the outside it possesses a platelet membrane shell. The TRAIL is attached on the surface of membrane and Dox is loaded in the core of nanogel. ( Hu, 2015 para. 1) 2) Explain the mechanism of how the nanoparticle system delivers the drug to…

Physicals techniques used are delivery catheter, coated stent, adventitial delivery and brachytherapy, to name a few. However, active methods used are using antibodies or targeting peptide to aim the drug at specific targets. In addition, nanoparticles have been used recently to improve the delivery and bioavailability of the active agent. (Wilensky, 2010). A nanoparticle is a particle that is less than 100nm in size and has magnetic and fluorescent material. It has a large surface area and is…

Nanoparticles (NPs) have piqued the interest of scientists because of their distinct physical, chemical and biological properties when compared to bulk material. These differences in characteristics can be attributed to the high surface-to-volume ratio (SA:V) of NPs compared to bulk material. Since NPs have a higher SA:V than bulk material, they are more reactive than their bulk counterparts; therefore, the surface characteristics of NPs can be easily manipulated. (Xuefei et al, 2014) Metal NPs…

The use of these nanoparticles will overshadow the harmful effects because they detect proteins, create fluorescent biological labels for important biological markers and molecules in research and diagnosis of diseases, isolate and purify biological molecules and cells in research. Most importantly, nanoparticles are used for gene delivery systems in gene therapy, which is the key factor for personalized medicine. These nanoparticles will cause a life time change in the field of medicine for…

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…

Abstract: This paper provides a brief summary of existing article Zinc Oxide Nanoparticles with Defects by Vladislav Ischenko,Sebastian Polarz,Dirk Grote,Victorina Sravarache,Karin Fink,and Matthias Driess. This paper discusses the importance of a nanoscale ZnO with defects in its structure. The article also provides a broad analysis of ZnO nanoparticles using a consolidation of techniques and the resulting data is summarised in this review. The paper gives the realization of when a…
