QUESTIONS FOR REFLECTION: 1.) What are other examples of nanostructures? By doing research I’ve found other types of nanostructures which are found in nature. On butterfly wings, the colors shown by a butterfly’s wings are actually contributed by pigments and the nanostructure of its wings. Another example is the gecko’s feet, the nanostructure in their feet allows them to climb on walls and stick on ceilings. 2.) What tools can manipulate nanostructure? The tools that can manipulate nanostructure are micro-fabricated grippers with electrostatic actuation, these are used for accurate positioning of nanoparticles, and environmental electron beam deposition, which are used for manufacturing nanostructures of diverse materials in a scanning electron microscope. 3.) How can nanotechnology address the problems in the environment? Nanotechnology is being used to improve the environment and address its issued By using nanotechnology we can address major environmental issues by producing nanomaterials that can upgrade products to be environmental friendly. It also helps in producing materials that are much more durable which results in prolonging the useful life of a product. This helps in lessening the amount of trash that are thrown. Nanotechnology is also being used to get rid of organic chemicals that are polluting ground water. Research have shown that nanoparticles from iron can be used to help clean organic solvents from water. And nanotechnology can also be used in reducing the pollution that are produced in manufacturing products. Scientists use silver nanoclustures to reduce byproducts that contribute to pollution in the process used to manufacture propylene oxide which is mainly used to produce plastics. 4.) How can nanotechnology be used in the prevention and treatment of illnesses? Nanotechnology can be a major help in the medical field. By the use of this technology doctors can diagnose patients earlier because it can detect diseases in the molecular level. And by nanosequencing the DNA doctors can know if a person has a genetic tendency for a disease. Nanotechnology can also help cure the patients by delivering drugs into the body with the use of

nanoparticles, this helps in delivering the drugs straight to the area where it is needed and it has a smaller chance of side effects. 5.) What is another example of nanotechnology and how does it work? Nanotechnology is also being used in manufacturing sporting goods. In lawn tennis, the racquets’ durability and strength are improved by adding nanotubes into its frames which can help improve the power of the players hit. It also reduces the air that comes out from the tennis balls which helps make the ball keeps its bounce longer. In golf, nanotechnology is used in producing better clubs and helping the player have a better swing.

ACTIVITY: 1.) Why is nanotechnology likened to creating a statue out of a pile of dust? It talks about how nanotechnology starts from to smaller things to create great and big things. Nanomaterials are really small materials but they can help manufacture products and structures that can make a difference. As the speaker said it’s like making a statue but rather from starting with a block of wood, you start with a pile of dust. 2.) What science governs nanostructures? Why is it different? They are governed by a set of physics that is called quantum physics. By making small changes makes a new structure or twists the whole particle. It’s like making a whole new aspect of technology because you can manipulate things in the molecular level. 3.) Why is nanotechnology a difficult science? Its small size that defines its ingenuity is also the same thing that makes it difficulty. Nanotechnology works with such small materials that makes it almost impossible to work with them. Another reference in making a statue with a pile of dust. And the process of nanotechnology is very slow which makes it frustrating for the people who are working on it.

4.) What does nature show about building organisms from the bottom up? Mother Nature has been using nanotechnology long before humans discovered it. Nature has always been building everything from the bottom up. It shows how nature can produce something big from using complex nanostructures. Nature showed how nanotechnology can build a statue with a pile of dust, from starting from the bottom up. 5.) How can chemistry help in nanotechnology? Chemistry helps in nanotechnology because it deals with molecules which are almost the same size as nanoparticles. By using chemistry we can obtain the materials that we need. And with the use of chemistry, these particles can be arranged to patterns and forms in order to fabricate products that can help improve nanotechnology’s scope in the lives of all the people in the world. So it basically aided nanotechnology to start making its promises into realities.
