Nanoscience vs. Nanotechnology Introduction Student Guide Lesson Overview In this lesson, you will learn the differences between â€Å"Nanoscience† and â€Å"Nanotechnology. † Both are extremely exciting, but have distinct differences in what the people in these fields do. Throughout this lesson you'll be asked to research and discuss what is happening in nanoscience and nanotechnology. A lot is going on in both fields and the potential for a lot more is HUGE. Before coming to class Complete the on-line Knowledge Probe (KP) called KP: Nanoscience vs Nanotechnology.Objectives At the end of this lesson you will be able to do the following: ?

In-class Activity: NanoScience vs. NanoTechnology In this activity you will develop your own definitions of nanoscience and nanotechnology based on current knowledge. You will be required to share your results with the instructor and other students as part of the class discussion.Discussion on the results of Activity You will share your definitions of nanoscience and nanotechnology with other students and the instructors. The discussion should cover the differences and sim ilarities of each. The instructor will present several examples of which you will determine â€Å"nanoscience†, â€Å"nanotechnology† or â€Å"both†. The class will reach a consensus on the correct definition of each. Post-Assessment Complete a short assessment that measures your understanding of nanoscience and nanotechnology.

What is it? First of all, what's the red spiral? What's the figure walking on top of the red spiral? Give up? Very simply put, the red spiral is a microfilament, a minute fiber found in muscle cells. The green figure walking on top of the microfilament is a protein molecule called myosin. Nanoscientists have discovered that the mysoin protein acts like a linear motor. To contract a muscle, the myosin molecule (or motor) walks in nano-size steps along the microfilament.As the myosin molecule walks, it pulls on the microfilament causing the muscle cells to contract. [Illustration by and courtesy of PrecisionGraphics. com] So what is Nanoscience? This is really a two part question: 1) What is nano? 2) What is science? By the end of this lesson, you will be able to answer these questions. You will also be able to answer the question – What is the difference between Nanoscience and Nan otechnology? There is a huge difference! So let's find out. UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG Page 3 of 10 Lesson Content What is Nano?Let's start with answering the question, â€Å"What is nano? † Here are some nano-size objects: DNA Molecule: DNA (Deoxyribonucleic acid) about 2 nanometers in diameter Dozens of Silicon atoms Each silicon atom is approximately 0. 234 nanometers in diameter; therefore this picture is about 4 nm wide. This picture was taken using an Atomic Force Microscope (AFM). [AFM image by and courtesy of Franz Giessibl] NanoDot This image shows a nano-size Gold particle (50 nm) sitting on the end of a microcantilever.

It can al so be applied to measurements that indicate the â€Å"amount† of something: milliampere or nanoamperes (an amounts of electrical current), microliters or nanoliters (the amount of a volume), and kilograms or nanograms (the mass of something). The prefix nano is used as another indication of size or amount. You may already know, or soon will find out, that a nanometer is defined as one-billionth of a meter (1 x 10-9 meter).A meter is a little longer than a yard (1 meter = 1. 09 yards). Graphic unit is â€Å"nanometer† Graphic source: National Cancer Institute What is Science? Now let's look at the second question: What is science? There are many definitions of science. Here are a couple: 1) â€Å"The systematic observation of natural events and conditions in order to discover facts about them and to formulate laws and principals based on these facts. †[Academic Press Dictionary of Science and Technology] 2) â€Å"The organized body of knowledge that is derived f rom such observations and that can be verified or tested by further investigation. [Academic Press Dictionary of Science and Technology] Sound pretty complicated? Well it isn’t really. It just takes some time to think about it. UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG Page 5 of 10 One way to look at the definition of science is that science is trying to figure out nature’s rule book. ? What are the rules which govern material properties? ? How do things move? ? Why do natural events occur as they do? An example of nanoscience was the discover of how the gecko can walk on ceilings and stick to glass walls of an aquarium.Hint: It has something to do with nano-size objects in the feet. You'll study this later in this course. Through science we know the answer to questions such as these: ? Why are plants green? ? Why do some things float and others sink? ? How do our lungs pull the oxygen out of the air? Scientists are the peo ple who do the investigations or experiments and try to determine what the rules of nature are. The experiments are done in a very precise and systematic way so that others can re-do the experiments and (hopefully) get the same results. Getting the same results is what is meant by being â€Å"verifiable† and â€Å"repeatable. So now you should have a better idea as to what science means: Figuring out the rules which determine how things work in nature. UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG Page 6 of 10 What is Technology? What does the term â€Å"Technology† really mean? We live in a society which is packed with all sorts of â€Å"technology†: iPODs, iPads, cell phones, laptops, GPS (Global Positioning Systems), gaming systems (Wii, Nintendo, X-box, Playstation), DLP (Digital Light Processors) displays, LCD (Liquid Crystal Display), WiFi †¦ I’m sure you can come up with dozens more technology driven devices and systems.How is Technology defined? The National Institute of Health (NIH) defines technology as â€Å"A body of knowledge used to create tools, develop skills, and extract or collect materials; the application of science (the combination of the scientific method and material) to meet an objective or solve a problem. † Merriam-Webster on-line dictionary defines technology as 1 a: the practical application of knowledge especially in a particular area b: a capability given by the practical application of knowledge 2: a manner of accomplishing a task especially using technical processes, methods, or knowledge.UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG Page 7 of 10 So What is NanoTechnology? Here are a couple of examples of Nanotechnology. Liposome A liposome is a tiny nanoparticle or vacated sphere made out of the same material as a cell membrane. It is hoped that one day we can fill a lipsome with drugs and inject it into the blood stream. Using the properties associated with the liposome's membrane, it will connect to a cancerous tumor, emit the drugs and kill the cancerous cells.Carbon Nanotubes (CNTs) Carbon nanotubes use the properties of carbon to form tubes with a length to diameter ratio greater than 1,000,000! Potential applications of CNTs include electrical connections for micro and nano-sized electronics, fibers 20 times stronger than bulletresistent kevlar fibers, and surfaces slicker than Teflon.

Activity: NanoScience vs. NanoTechnology Link to and complete the activity – Nanoscience vs. Nanotechnology UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG Page 8 of 10An Example of Nanoscience Enabling Nanotechnology Now that you have developed definitions for nanoscience and nanotechnology, what do you think is the difference between the two? In this picture you see a dep iction of a molecule. This particular molecule makes up the famous non-stick Teflon coating used on cookware, telecommunication cables, and clothes. Identifying the molecule's design and determining its physical and chemical properties are examples of nanoscience. Learning how to control and mass produce the molecule to make the desired Teflon coatings is an example of nanotechnology. [Images by SCME]More on Teflon Coatings The molecules that are used for Teflon coatings repel water molecules when assembled in a film. These Teflon coatings are said to be hydrophobic. â€Å"Hydro† means water and â€Å"phobic† means â€Å"scared of† or â€Å"repulsed by. † Nanotechnology has lead to the development of a process that takes billions and billions of these molecules to make a continuous coating. The result is a hydrophobic surface called a Teflon coating.
