纳米生物科技

今天花了不少时间
做literature search
现在眼睛累累的

做完这些搜查之后
心里有点小感触
好像我站在这个山头很久了
现在赶下去另外一个山头
然后发觉我要去的那个山头
就是大家沸沸扬扬在讨论的热门山头

现在有点担心是,那个山头会不会很难爬?哈哈。

对于所谓的“纳米技术”
应该不觉得陌生吧
可是常常从电视科技频道或者新发现频道听到的词语
到底是什么意思呢?有没有想过?

Wiki是这样解释的:
Nanotechnology is a field of applied science and technology covering a broad range of topics. The main unifying theme is the control of matter on a scale smaller than 1 micrometre, normally approximately 1 to 100 nanometers, as well as the fabrication of devices of this size. It is a highly multidisciplinary field, drawing from fields such as applied physics, materials science, colloidal science, device physics, supramolecular chemistry, and even mechanical and electrical engineering. Much speculation exists as to what new science and technology may result from these lines of research. Nanotechnology can be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more modern term.

Nanotechnology这个词是在1974年由一位日本科学教授所提出的
从那时候开始到了现在
所谓的纳米技术发展到了多方多面
几乎任何一种科学技术
只要是有nanometer的dimension都可以considered as nanotechnology吧

看看BBC怎样介绍Nanotechnology吧,很复杂的科技也能有很简单的解释的,:)


既然大家都有自己的nanotechnology
生物界也开始出现bionanotechnology的名词出来
但实际上,生物学家很早以前就在做nanotechnology了
不是吗?我们每个人身体里面的DNA,就是nanometer的大小的
人类开始对DNA有真正突破性的了解时是在1953年左右吧
所以说生物学家是不是比较有前瞻性?哈哈

离题了离题了
重点是
虽然我要爬上去的是大山头中的一个小小的山角
但也蛮开心的
至少我踏的是最热辣的一淌水
嘿~

加油!
(休息一下眼睛)
(以便看更多的资料去~)

我曾經在報章看過纳米的專題報導
我真的很仔細的讀, 過後也全忘了...
現在仍然看得有點一頭霧水..
看英文又會頭昏.... 賤命吶....
