Nanoparticles are so small in size that they can enter cells and organelles to interact with DNA, proteins, enzymes while circulating throughout the body. Therefore, nanotechnology is used in detecting disease in a very small volume of cells or tissue [1].As mention above; commonly used nanoparticles are such as, gold nanoparticle, silver nanoparticle, quantum dots and magnetic nanoparticle. Gold nanoparticles have unique stability against oxidation which makes it useful in diagnostic. Its benefits such as much reduced or no toxicity, much better contrast agents for imaging, and surfaced-enhanced and distance- and refractive index dependent spectroscopic properties compare to other nanoparticles, makes it the best choice of selection for enabling early diseases detection [2,3].

The use of nanoparticles for the detection of experts is a topic of interest that is being passively discovered for many applications [4]. Firstly, the capability of a nanoparticle to identify a tissue of interest is perhaps the most potential abilities in nanotechnology. Nanoparticles are used in selectiv...

    Amandi Hiyare: Before forming my research question, I had a discussion with my research project coordinator “Lisa Pope” who told me that the Flinders nanotechnology research team has been developing microbial catheters. Then on Monday I had an interview with Professor Joe Shapter who told me that your team was leading this project. So I was wondering whether you would be able to provide me with some detailed information about this innovation?

  • Rhetorical Analysis Of Pinpointing Cancer Fight By Liz Szabo

    379 Words  | 1 Pages

    In the article “Pinpointing Cancer Fight,” Liz Szabo states the uses of nanotechnology and how researchers are attempting to use this advancement to fight cancer. She defines that nanotechnology is a type of technology that creates devices on an atomic level; this equipment can allow people such as researchers to use its ability to detect cancerous cells as well as treat them. Szabo remains a neutral tone as she states that while some are against the idea of using nanotechnology since there are many risks, others are optimistic that it may lead to transformational results. She presents a list of some products developed through nanotechnology and explains its usage in addition to mentioning the failure of those nanotech products. Szabo provides

    They have a larger surface area in proportion to their volume. This enables them to interact with different types of biological systems and provides a wide variety of possibilities (Nuruzatulifah, Nizam, & Ain, 2015). The nanoparticles can be seen by transmission electron microscopy (TEM). When there is one nanoparticle, it is called a primary particle. When there is more than one, it is called a secondary particle. In order to measure these particles, they need to be suspended in a solution (Pruneanu, Coros & Pogacean, 2015). Dyed nanoparticles or internally fluorescent nanoparticles barely interact with cellular proteins which is what the study requires. They are also quite easy to manipulate. They can be easily internalized into cells and can be programmed to go to specific sites (Wolbeis,

  • Silver Nanowires

    683 Words  | 2 Pages

    This project is focusing on the shape of silver nanoparticles and the aspect ratio of silver nanowires for the control of their absorption spectrum in the visible light to infrared ranges. Synthesis of metal nanoparticles has become increasingly important in science and engineering. Being able to control the processes is vital to success in applications and uncovering the mechanisms of nanoparticle production. Nanowires are one of the varieties of nanoparticles that will be utilized for this project. There are many different metals that can be used to synthesize nanowires, I am focusing on silver. Silver exhibits the highest thermal conductivity out of all metals (Sun, 2001). Silver nanowires with a large aspect ratio also show an absorbance of higher wavelengths then other nanoparticles, like spherical silver nanoparticles (Sun, 2001). Other silver particles that exhibit similar characteristics and show a higher wavelength absorbance will be considered as well. Controlling reaction conditions allow plasmonic, oscillatory quantum motion, colloids to obtain architecturally predictable nanostructures and can be used to understand their optical properties (Motl, 2013). There are many shapes that nanoparticles can take up. Each shape, on the nanoscale shows different properties that can be utilized, such as conductivity, anisotropy, and, what I am interested in, absorbance of light.

    ...nessing “the power of nanotechnology” to radically change the way we diagnose, treat, and prevent cancer.” The most likely method implemented will by the use of nanovectors for targeted delivery of anticancer drugs, and then heating nanoparticles that are attached to cancer cells so that the cancer cells explode. (5, 9) There are still many obstacles that must be overcome before this is a reality: from the ethical concern by some that nanobots will take control of the body to the more practical problem that this method of treatment will be very expensive and funding will be an issue. (6) But with millions of people suffering from some form of cancer, scientists are searching for cures and treatments and nanotechnology offers the greatest promise. One day, cancer may be completely curable thanks to nanotechnology which is something everyone would benefit from.

    Gold NPs are one of the most popular NP that have been widely used in researches for their inertness, biocompatibility, easy synthesis in different sizes and shapes. Due to their small size, gold NPs are absorbed in blood circulation and they have good permeation in tumor tissue. This is called enhanced permeation and retention effect (EPR). Due to their unique optical properties and high z (z= 79), AuNPs are ideal for hyperthermia and radiation sensitization, respectively.

  • Nanook Of The North Essay

    588 Words  | 2 Pages

    Nanook of the North is a documentary film about Nanook, an Inuk man, and his family. The film was released in 1922 and was created by Robert Flaherty. The documentary received a lot of back lash because many of the scenes were believed to have been staged rather than filmed in the moment. Nanook captivated audiences with his heroic demeanor, which was a plus in the film’s success. Throughout the film there are various scenes where Nanook and his family members look directly into the camera, which is a part of the “proof” and “lesson” of documentaries. Proof is how much one can manipulate a documentary, but can still teach the audience a lesson.
