Nanotechnology: Will it save us or destroy us?

Extracts from this document...

Introduction

The topic of this essay is Nanotechnology and this essay will be representing both sides of the controversial matter for whether or not this latest development in technology will lead us to prosperity or devastation, success or downfall. Nanotechnology is an upcoming development in our science departments and is also believed to have the potential to change the world, whether for or for worse is still being disputed. The institute of nanotechnology states that, "It offers ways to create smaller, cheaper, lighter and faster devices that can do more and cleverer things, use less raw materials and consume less energy."[1]. However, there are people that simply say, "developing countries aiming to commercially exploit nanotechnology is quite a naive illusion", like Canadian activist Pat Mooney [2]. The conversion of one nanometre is one-millionth of a millimetre. With the Nano scale, objects are so small that we can't see them with the naked eye or even with a microscope. ...read more.

Another use of nanotechnology is in the conservation of energy. These days, we need to be extremely careful about how much energy we use due to the extremity of global warming. Nanotechnology provides a solution to use the least amount of material to continue the operation of many things used everyday such as means of transport being made more energy efficient and common domestic furniture such as a sofa being light enough to carry with a single pair of hands. Nanotechnology has reached the public on a global scale. In Japan, The Sangi Company Ltd. Has developed a line of products using nanoparticles with their first production of toothpaste that can repair broken enamel. The way it works is the Nano sized particles synthesize with the particles found on the enamel and the particles present in the toothpaste form a protective film over the teeth. This is a dream come true to those who fear their next dentist appointments. ...read more.

Conclusion

The nanoparticles, are actually quite dangerous especially when inhaled. Its effects can be fatal, even causing death. Some may say that nothing is worth losing a life, this point leads me to my conclusion. To conclude, and readdress my opinion, although there are negative sides to nanotechnology, it is something that can hardly be avoided. After all, almost every single medicine has it's side effects. I believe that the positives outweigh the negative points. Chemotherapy has its down points and can even reverse the healing effects of its treatment. So every invention and discovery needs some work and safety regulations but not every disaster can be avoided. I truly think that nanotechnology is the way forward.

Response to the question

Although the coursework is shorter than what is should be, it provides a concise and objective response with effective use of sources. For example he writer clearly displays that nanotechnology could be 'commercially exploited' if it gets in the wrong hands but also be the most cost-effective creation ever produced. It is impressive that the response repeatly refers to surveys or reputable scientists; this suggests that he has tried to find reliable sources. I would improve this by actually assessing the reliability of the sources in the coursework. At times the response feels like a diary entry rather than a GCSE standard coursework- for example the use of the phrase 'caught my eye' is unnecessary in this content.

Level of analysis

There definately isn't much to assess on the level of detail; way too broad to be able to gain a decent mark. But each of the points are completely relevant with a source supporting their argument. Ethical, social and economic implications are indirectly discusses such as nanotech weapons leading to an arms race and being used as a destructive weapon to kill masses. The conclusion is well structured weighing out the benefits with the risks. To improve I would research a study looking at the effects nanoparticles have when inhaled. This would support the point being made and help formulate a stronger argument.

Quality of writing

Grammar, punctuation and grammar is good. At times there are phrases such as 'in the middle of this essay piece' which are not required at all. Use of technical terms could be improved to gain a higher grade. Overall it is a well structured response with an aid of image that helps understand the argument better.

  2. Investigating the Factors Affecting the Temperature Change Between Zinc and Copper Sulphate

    This can be confirmed by looking at the results obtained: When 1g of zinc powder is added, the temperature is 9.8g; When 1.2g is added, the temperature is 10.35g; When 1.4g is added, the temperature reaches 10.8g. Before I conducted my experiment, I predicted that as more zinc was added, the temperature would rise.

    If it doesn't, then the readings would be wrong because after putting an object on the scales, it would display the mass of the object and the mass of something that isn't there. This is why it's important to calibrate it by making sure it displays '0.00g' when there is nothing on the scales.
