I have never been thought before that I will attend this kind of class. Very futuristic and unimaginable lesson. What the lecturer say is about the combination of the two main technology that is biotechnology and nanotechnology. Sometimes during the class I just can’t stop thinking (with absolutely imaginative mind!) how could that stuff be real??
Anyway, today is the last lecture, and the lecturer tell us about the future of bionanotechnology. I think this is the peak of several lesson before, that explain us about the DNA origami (This is the first time I heard that we can make origami from DNA!), DNA combining semiconductor, Nanorobot for medical therapy, gene therapy, gecko’s feet for everlasting glue tape, etc. Very interesting I think. And the nice one is : the lecturer isn’t a Japanese, so he can speak in English very very very well.. hehe
Here are some nanotechnology from nature: The idea is mimicking the nature.
The Gecko and Its Feet. Gecko has feet that covered by 500.000 setae/ foot, and each setae contain 100-1000 spatula in nanostructure. The structure can make gecko attach the wall tightly using van der waals interaction and capillary forces. So that, in theory, a single gecko can support more than 2 Kg weight hanging despite gecko have only 40g in weight. That’s why then people mimicking the feet nanostructure to make a everlasting glue tape. A glue tape that no need a glue anymore because of van der waals interaction and capillary forces. And the tape can be used over and over.
Spider Silk. Did you know that spider silk is very tough and much lighter than steel?! That nanostructure make it have extra properties in toughness, strength, and flexibility. So that people trying to mimic it to make a high quality surgical thread.
Lotus Effect. The nanostructure of lotus make it hydrophobic and let water on it always fall down and never make it wet. The always-falling-down water make the leaves always clean. That is because the lotus leaves have wax hydrophobic crystal around 1 nm in diameter. Then, what people mimic from the lotus is to make a wall paint that can wash its self when the rain come.
Then,let’s go to biotechnology inside! what the scientist still researching and developing about is Continue reading
