Gold Nanoparticles for Diagnosis and Treatment of Cancer Abstract—Nanotechnology has been an extremely hot topic over the decade. It is the science‚ engineering and technology conducted at nanoscale. Two of the main applications of nanotechnology include material science and biomedicine. We have achieved great strides in applying nanotechnology to material science that is well justified by the decreasing size of electronics available in market. However we haven’t made a mark in biomedicine yet

SUMMARY AND CONCLUSION 6.1 Summary Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical‚ chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such as

Nanotechnology is defined as “the manipulation or rearrangement of matter in dimensions 1 to 100nm also known as nanoparticles” (What Is Nanotoxicology?‚ 2013). The rapid development of nanotechnology is believed to have significant benefits on mankind. However‚ as with possibly all developing technologies‚ there are bounds to be risks associated with these benefits. To assess these risks‚ a new discipline known as nanotoxicology has emerged and is corresponding with nanotechnology. Nanotoxicology

Effect of surfactant. The stability of the nanoparticles largely depends on the type and concentration of the surfactant(s) used. 5.5.1.1. Effect of different surfactants Three batches of nanoparticles each were prepared with different surfactants (Pluronic F 68 and PVA) and their effect on particle size‚ entrapment efficiency and yield was observed (Table 5.1).

Mechanisms of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related
