Nanotechnology For Fly Fashion

fly eyeglassesDoes the picture on the left makes this post look like a joke? Think again. This preserved housefly is sporting a pair of two-millimeter-wide eyeglasses, engineered with ultra-precise fast-pulse laser technology. I guess you must have really big brains to play with this kind of advanced tech. Kudos!

Nanotechnology is an experimental field of applied science and technology. It covers a broad range of topics and is focused on controlling and exploiting the structure of matter on a scale below 100 nanometers (a meter is equivalent to one billion nanometers). An ultrafast pulse of light is an electromagnetic pulse whose time duration is on the order of the femtosecond (10− 15 second), ie. it is one billionth of one millionth of a second. Once impossible to observe, ultrafast phenomena are now extensively studied thanks to advances in the design of pulsed dye lasers.

Ultrafast Lasers can be used to process all kinds of materials with extremely high quality and reproducibility. Unlike conventional laser processing, ultrafast laser machining reduces damage to the surrounding area, such as melt zones, micro-cracks or debris, thus making post-treatment unnecessary.

However, I will be looking forward to more practical uses of nanotechnology, such as robots used for treatment inside human bodies. What are your thoughts?
