INTRODUCTION TO NANO BIOTECHNOLOGY
Nano biotechnology are terms that refer to the connection of nanotechnology and biology. Given that the subject is one that has only appeared very recently, bio nanotechnology and Nano biotechnology serve as complete terms for several related technologies.
This discipline helps to indicate the blend of biological research with several fields of nanotechnology. Concepts that are developed through Nano biology include: Nano devices (such as biological machines), nanoparticles, and nanoscale phenomena that occurs within the discipline of nanotechnology. This technical method to biology allows scientists to visualize and produce systems that can be used for biological research. Biologically encouraged nanotechnology uses biological systems as the encouragements for technologies not yet produced. However, as with nanotechnology and biotechnology, bio nanotechnology does have many possible ethical issues associated with it.
Recently, the use of microorganism to produce efficient nanoparticles has been of great concern. Microorganisms can change the oxidation state of metals. These microbial methods have released up new openings for us to discover novel applications, for example, the

Quantitative information has been gathered about the surface structure of membrane proteins to lateral and vertical resolutions of 0.5 nm and 0.1 nm, respectively, about the forces that keep protein–protein and protein–nucleic acid assemblies together as well as single proteins in their native conformation, and about the Nano mechanical properties of cells in health and disease. Such progress has been achieved mainly because of constant development of AFM instrumentation and sample preparation
Amanda Ellis: I guess you would call it ‘Bio-mimicry’. As you are at a very small scale ‘nano-scale’ which is beyond white blood cells and red blood cells, nanotechnology fools the body that it is a normal material. A lot of studies go looking at biocompatible polymers, which are polymers that are bio compatible in the sense that the body does not find it toxic. There are a lot of people that are working with DNA nanotechnology. An example of Prof. Ellis’s research is delivering cancer drugs through a DNA strand with the use of a nano-scale box. Humans have DNA, which is about 50% different than a banana. As DNA is
Many people feel that biology has become more advanced than physics. Biology has in fact become the new focus of the future as we tend to use it a lot in our daily lives. The study of Biotechnology is known as the branch of molecular biology that studies the use of microorganisms to perform specific industrial processes. This study shows that our lives can be transformed.
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
With a consequentialist tone of approach, he describes human society having an imbalance between two ideals: the acceptance of oneself as a gift and the strive for perfection. The usage of technology for enhancement purposes pushes us away from the first and more towards the latter. Bioethics’ main principle revolves around the concept of morality, defined by beliefs regarding actions that are often split between being right or wrong in interpretation and character (Vaughn). Sandel upholds to this stance, confronting it with our own ideology that through the pronouncement of terms of biotechnology, we seem to accept more than reject what is brought up in the culture of society, this type of thinking reaffirming our current beliefs of the nature of controversial
The advancement of progress in the fields of biology and technology and, by extension, the scion of these two fields – biotechnology – is generally being lauded by experts and laymen alike. Genetically modified foods, Dolly the sheep, stem cell research and therapeutic cloning are but some of the achievements in this field that have changed the scientific landscape, drawing attention to the past, present and also potential future exploits of men and women involved in biotechnology. Mainly because it is becoming increasingly apparent that the field may, in the near future, extend beyond therapy into human enhancement. With the possibility of such expansion looming ahead, it may be prudent to question whether or not such enhancement is morally and ethically desirable within the context of human nature and also nature itself. And although transhumanists, advocates of enhancement, themselves agree that there are concerns such as potential danger to health, technological difficulty or the impact on the environment tied to human enhancement, their opposite numbers from the bioconservative side of the divide feel that there is much more to be concerned about. Some even argue that the idea of human enhancement beyond therapy, or in other words makign ourselves “better than well”1 is inherently flawed. In any case, should human enhancement in its many forms become commonplace, it is surely going to “affect the rate of human intellectual, material and political progress”2. This essay will focus on illustrating the conviction of the bioconservatives about the detrimental nature of human enhancement in relation to two hypothetical but nonetheless very controversial forms of it – expansion of human cognitive abilities using nanotechnology and ...
Before we begin to delve into the ethical depths of biotechnology and genetic engineering, we must first understand how this technology works. To do this let’s start by discussing cells. All organisms are made up of microscopic entities called cells. The human body consists of about ten trillion cells of about two hundred different types, such as skin cells, blood cells, and muscle cells. To gain a general understanding of how cells work, we will look at some of the simplest cells possible- bacteria cells. Once we have an understanding of how bacteria work, it is not hard to see how cells function in other organisms.
In order to fully understand the uses of human enhancement and biotechnology, one must first decipher their purposes. Human enhancement is typically referred to as improving the overall functioning of a human being, both physical and mental. Biotechnology is a process that often results in human enhancement and is often achieved through genetic manipulation, nanotechnology, and cybernetics. Because of their power to completely change the human race, there is a a very fine line when it comes to the proper use of such technological advances. A key point is the difference between this technology’s use for therapeutic purposes as opposed to the
Nanotechnology includes nanorobots which are so small that they can be injected into the human bloodstream after which the nanorobots can do investigations or repair at cellular level. Nanorobots could optimize the delivery of pharmaceutical products, these means that medicines which are targeted on a specific type of cells can be delivered to only those cells by the nanorobots. The robots can attach to the cells after which they can inject the drug into the target cells. This could be a great breakthrough for cancer treatments such as chemotherapy because there is a minimal chance of injecting healthy cells with the drug and therefor negative side effects can be avoided.
There are many specific areas of future direction regarding synthetic biology for research and development. Along with that come different social, economic and environmental/political impacts of potential future developments. In the article “How to Best Build a Cell” biologists and engineers work together and discuss how to build the best genetic circuits for use (Collins). Recently the study has engaged very few biologist and is still in the infant stage of development since we don’t know enough about biology to make synthetic biology a predictable engineering discipline. Synthetic biology has already brought us some useful things such as whole-cell biosensors, cells that synthesize anti-malaria drugs, and bacterial viruses designed
The purpose of this document is to learn about the new and exciting developments in the biotech industry. Besides lives being effected, the companies and the markets in which they reside will be as well. It’s vitally important to learn about the new technologies since there is a very good chance that million’s of others, and mostly likely yours truly will ingest a new drug, or have a new procedure preformed.
This means that the ethicality for synthetic biology is mostly based on predictions for the future. However, the ethicality of synthetic biology can be determined by applying the principles of laws for bioethics and emerging technologies to these factors. Social implications are the most important factor when it comes to considering how ethical a technology is. As of 2010, the Presidential Commision for the Study of Bioethical Issues developed a set of basic principles to assess emerging technologies based on some of their social
Nowadays as the population grows increasingly, the need for food and medicine also increases. Meanwhile, in order to meet their basic needs, human societies have turned to different plants. And so far several studies have been conducted so as to get the most out of plants in different food and medical fields. On the other hand, with the advancement of different sciences, we witness the use of a variety of conditions for better growth of plants. One of these sciences which has had increasing developments in the last century is nanotechnology. In recent years, Nanotechnol...
Nanotechnology has found many potential applications in the area of functional foods by engineering biological molecules toward functions very different from those they have in nature, opening up a whole new area of research and development.
Biotechnology is a group of technologies that work together with living cells and their molecules to prolong life (Keener and Hoban et al., 2014). Today biotechnology can be used in a variety of ways such as in an industrial setting where they use it to create enzymes to synthesize chemicals, in an environmental setting where they use it for waste and pollution prevention and lastly it can be used in medical applications such as in pharmaceuticals, genetic engineering, DNA fingerprinting and in lastly it can be used in stem cell therapy (Keener and Hoban et al., 2014). Everyone in today’s society depends and uses biotechnology in one form or another, biotechnology is essential for our health and wellbeing.
The procedures that will be the future of modern medicine currently fall into the realms of taboo and fictional. These procedures encompass every aspect of medical science, from exploration of the human body, curing diseases, to improving a person’s quality of life. Many of these procedures are not very well known, while a few have been in the spotlight. These procedures include cloning, nano-robotics, retro-viruses, and genetic manipulation via gene-specific medications. For any serious breakthroughs in modern medical science, we must embrace these new forms of treatment instead of shying away from them. Second, I’ll attempt to explain how these methods and procedures could benefit mankind.
