Nanotechnology

Hi blogger... i am sorry i could not share anything to for one month. i was busy because i had many assignments that always came after one and another. furthermore, the connection was really bad too... :(

do you hear about nanotechnology before?

according to center responsible nanotechnology (2002), nanotechnology is the engineering of functional system on an atomic and molecular scale. it is also used techniques and tools in order to constructs items from the bottom to up.

furthermore,  based on Wikipedia (2013), scientists currently debate regarding the  future implications of nanotechnology. in this case, there are advantages and disadvantages of nanotechnology. the advantages might be able to make many new materials and devices with huge range of applications like in medicine, electronics, bio-materials, and energy production. however, it can raise other issue such as toxicity and environmental impacts of nano materials.

likewise, as described by the U.S. National Nanotechnology who is Mihail (Mike) Roco, nano technology has  four generation. First generation is for a passive nano-structures to perform one task, second generation is for multitasking such as actuators, drug delivery services and sensors, third generation would interact with thousands component in 2010. lastly, it is expected to be developed.
here is the chart of nano generations:

 overall, nano is general purpose of technology that was written by center responsible nanotechnology,"Nanotechnology is sometimes referred to as general purpose technology. That is because in its advanced form it will have significant impact on almost all industries and all areas of society. it will offer better built, longer lasting, cleaner, safer and smarter products for the home, communication, medicine, transportation, agriculture and for industry in general."
