A new study published Monday comes with a video recording of the collision of organic nanoparticles, and the footage is inherently groundbreaking as this is a rare sight from which researchers can learn a great deal. Seeing nanoparticles in motion, especially including collision, is predicted to be a boon for the development of new drug delivery methods. The video also serves as an impressive illustration of how the ever-changing imaging technique of modern molecular study is rapidly becoming increasingly capable of capturing the nuances of nano-molecular motion. The sight of moving particles in and of itself is a bijou; the dynamics of which yield the confluence of two bubbles into a single bubble. The footage starts with the …show more content…
A postdoctoral fellow in Gianneschi’s research coterie at the National Institutes of Health, Parent says that many studies like this will inevitably follow wherein scientists use this same method to examine all manner of behavior from organic, nanoscale materials. “Capturing the fundamental growth and evolution of these particles in motion will help us immensely in our work with synthetic materials and their interactions with biological systems,” says Gianneschi, who serves as the Jacob and Rosaline Cohn Professor of Chemistry in the Weinberg College of Arts and Sciences. Neither he nor Parent has likely underestimated the significance of this study in light of the prospective influence it may very well have on future research. In fact, new insightful studies can now be published simply based on recordings of feats already accomplished with nanoparticles because the value will be not in the feat itself but, rather, in the well-defined recording thereof. Much like the value in Gianneschi’s study, it would be in learning more about the dynamics and behavioral parameters of nanoparticles. Perhaps the greatest measure of the potential that this study represents, in fact, is the sheer scope of all the things for which nanoparticles and nanotechnology are already used. Earlier this month, in fact, the scientific community was somewhat surprised to find that a study illustrated the injection of
However, only experts like scientists and researchers who studies on the said topic have conceptual ideas about nanotechnology, about the advantages and disadvantages of the up and coming field of science. The founder of nanotechnology, Eric Drexler, said that his discovery can solve the many problems of society such as the lack of food, medicine, energy, and power. Professor Therese Rosbero, a lab professor in DLSU-Manila, stated that nanotechnology is a field of science in which other products of science such as biology, chemistry, physics, and medicine are applied all at the same time. She said that nanotechnology is composed of nanoparticles which are too small to be seen by the naked eye (Personal communication, 2015). On the other hand, most of the people in the society have zero to no knowledge about the inner parts of nanotechnology. At the early ages of nanotechnology, the public’s perception about nanotechnology is all about optimism and excitement as it poses potential life changing benefits (Priest, 2012). However, that perception of the people about nanotechnology changed as the once hidden properties of nanotechnology are slowly showing their capability to be harmful and less beneficial to society. Even though most of the people do not know anything about
Ricardo Morales on the synthesis and characterization of bimetallic magnetic nanoparticles for further application in cancer treatment, I gained the skill sets needed to come up with research ideas and implement them as well as how to resolve issues that arise within any research. My experience as a teaching assistant in organic and general chemistry at the University of La Verne Chemistry Department taught me the importance of lab safety and the joys of connecting what is learned in lecture to lab and helping students make that connection in a lab setting while creating a safe environment. My experience as an Academic Success Center tutor in chemistry course from general chemistry to advance organic chemistry taught me the joys of helping students to truly understand material and not memorize it but have that knowledge become a part of them that they can use whether in a research setting or to explain those concepts to their peers. These experiences in undergrad allowed me to determine that academia was the right fit for me; graduate school will give the skills needed to fulfill this
Nanoparticles (1 000 000 times smaller than a millimetre) are manifesting to be a great success in nanomedicine’s discovery of supplementary methods of fighting against superbugs. At the University of Colorado, researchers have utilized nanoscale quantum dots, which are “miniscule semiconductor particles with specific light-absorption properties, to kill drug-resistant superbugs without harming the surrounding healthy tissue,” (Nagpal, 2017: para. 2). Nanoscale quantum dots that are activated by a light source perturb the balance of chemical processes in threatening bacteria that would kill them.

“This work has led many other investigators around the world to study this nanomaterial, but we were one of the first groups to study these nanoparticles in a biomedical context.
I first felt thrilled in pursuing scientific research, when I learned about critical aspect of materials chemistry in the elucidation of nanoparticles for drug delivery systems in organic chemistry with Prof. Sunasee. Since then, I host a passion for academic and research traing designed to prepare me for graduate studies in the development of nanomaterials and nanotechnologies for healthcare. My primary research interests are in the fields of nanotechnology and materials chemistry for drug therapy and cancer biology (of the p53 and pro-apoptotic signal transduction pathways).
My experiences during my undergraduate and professional careers have had profound impacts on me by providing opportunities for self-discovery and allowing me to explore my interests. At the University of Pittsburgh Chemical Engineering Ph.D. program, I hope to explore my interests in nanotechnology, surface chemistry interactions, and
The encapsulation and site-directed mechanisms can also be translated and utilized in bioimaging – the field of study concerned with developing imaging techniques and devices that are used to obtain anatomical images and provide tissue analysis. Medical professionals are always looking for answers as to what is going on inside one’s body. Nanoparticles can serve as excellent scaffolds in this area of research because they have such a high surface area- to- volume ratio [9]. Ferritin, in particular, has been modified in different ways, mainly using the techniques described earlier, to further advancements in this field.
Nanotechnology is a recently developed technique to produce nanoparticles. According to the definition from British Standards Institution, nanotechnology refers to the intentional design, characterization, production and applications of materials, structures, devices and systems by controlling their size and shape in the nanoscale range1. Nanotechnology covers versatile applications, such as medicine. Nanomedicine is defined as the field of medicine that aims to use the properties and physical characteristics of nanomaterials at the molecular level2. In general, nanomedicine exhibits tremendous advantages over conventional medicine. Therefore, it is widely applied for various purposes, for instances, diagnosis, prevention and treatment
Second, nanosilicates, which are incorporated into a matrix of gelatin, can interact with polymeric chains. This will have a positive effect on certain physical, chemical and biological characteristics. [Janet R. Xavier et al. February 2015]
Nanotechnology is one of the most advanced and well reputed branches of modern sciences. Nanotechnology is handling of matter at the atomic or molecular level. Scientists from all over the world are now considering forthcoming effects of nanotechnology on human and environment. Nanotechnology is likely to be crucial to the 21st century scientific and medical advancement and its developments will be determined by the collective hard work of natural, physical, medical, engineering and related sciences. The materials in Nano scale can show different properties compared to what they exhibit on a macro scale. A nanoparticle by definition is, an ultra-refined particle that has all the dimensions in the Nano range i.e. from 1nm to 100
The manufacturing process of nanomaterials leads to release of certain waste products, which can float in air or even penetrate animal and plant cells.
Nanotechnology is the study of particles on the nanoscale with, at least one dimension being less than 100nm. (Chen, Schluesener, 2008) Nanoscale particles can come in many shapes and sizes, ranging from 100 - 1 nm. These particles can be found as rods, cones, spheres and many more complex matrices and patterns as seen in figure 1.(Champion, Katare, Mitragotri, 2007) Nanosilver will form a roughly spherical shape as can be seen in figure 2. (Utopia Silver Supplements, 2012)
The field of Nanotechnology involves the manipulation of infinitesimally small matter. The National Nanotechnology Initiative defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. By employing nanotechnology and its opportunity for miniaturisation in the development of consumer products, we have placed ourselves on a paradigm changing technology path permitting considerable efficiency savings in terms of cost, energy and resources. These developments would surely have not been possible without the avail of nanotechnological processes. Accordingly, the field of nanotechnology is a rapidly expanding and major innovative force amongst the scientific community, and the increasing
Nanotechnology has expanded human capabilities to perform tasks by manufacturing nanostructured materials with certain properties, properties which we use in many different areas. In the Medical industry, nano-gold particles are being manipulated to have bacterial detecting properties. Nanotechnology simply is “ The branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules.” This technology is specifically useful in the medical industry where the shape and size of specific nanoparticles led directly to the problem, for example cancer cells or specific bacteria cells. But, the size of the particles impact the properties of the particles.
