Antibacterial and biomedical applications of gold nanoparticles and Essay

Antibacterial and biomedical applications of gold nanoparticles and graphene composite - Essay Example Graphene has oxygen-containing groups embedded in its honeycomb-like six-atom carbon rings. Graphene oxide (GO) is used to in imaging and delivery of drugs (p.365). Georgakilas et al. says that the existences of carbon nano-structures in graphene enables it to form organic polimers which are very important in the formation of polimer composites which are important in biomedical application (p.4). also supports Yang et al. on the issue (n.d, p.1-59) T Yang et al. (2013), continue to say that the properties of graphene is also useful making of biological, pathogenic and pharmacological processes that make it necessary delivering therapeutic drugs since its used for the detection of specific proteins through the â€Å"sand witch † immunoassay which is useful in the binding of proteins and secondary antibody. This is why the graphene is used in the creation of cancer-detection biomarker. This occurs when the layers of graphene are used to increase the surface area for capturing large amounts of Ab1 and when it is further amplified; it achieves multi-enzyme-Ab2 which is functionalized carbon nanospheres (Yang et al. 2013, p.367). Graphene is also used in quenching the fluorescence of other fluorescent dyes which is used in fabricating fluorescence resonance energy transfer (FRET). FRET sensors are used for monitoring ssDNA (Yang et al. 2013, p.367). According to Polte et al. (2010), Gold can be used in various fields of medicine, biotechnology, and catalysis. This makes it one of the most important subjects in the study of nanoscale materials. Gold nanoparticles are prepared using various processing routes like chemical, sonochemical and photochemical paths. However it is mainly made through the precipitation of the GNP in aqueous solution from dissolved gold precursors like HAuCL4 using reducing agents like sodium citrate, ascorbic acid, sodium boron hydride or block copolymers which

Traditional Chinese Culture Essay Example | Topics and Well Written Essays - 1000 words - 10

Traditional Chinese Culture - Essay Example The Chinese traditional distinct language is a cultural value that establishes a mutually tolerant and universally embraceable world order. Language is a communication symbol that connects the Chinese citizens with external contacts. This is because a person has to learn the traditional Chinese language in order to transact business with the locals (Zhang 9). The distinct grammatical and phonological set up of the language inspires interest among foreigners. Similarly, the unique writing style requires one to understand the sentence formation for easy communication. For instance, business interactions require the usage of a common communication model understood by all partners. The traditional Chinese language has been studied across the world because the country boasts of sophisticated industrial and technological advancements (Zhang10). As a result, this has inspired a mutually tolerant and universally embraceable world order where people from diverse backgrounds come together to l earn a common language. Religion is always a unifying element that brings together believers to embrace and accept each other. China has three main religious denominations that people profess to for spiritual nourishment and divine intervention. The Confucianism, Buddhism and Taoism have contributed to the Chinese civilization through their spiritual teachings. Buddhism is the most practiced religion in the country and spreads across other Asian nations (Zhang 15). The social and ethnic relevance of the religious associations has enabled the believers to develop their generation. It is apparent that Buddhism has had a remarkable contribution to Chinese civilization because most of the words and phrase used in the country have roots in the Buddhist origin.
