What is it? introductory of all, whats the red spiral? Whats 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 carrells. The spurt figure walking on top of the microfilament is a protein subnuclear particle called myosin. Nanoscientists have pecked that the mysoin protein acts like a linear motor. To contract a muscle, the myosin molecule (or motor) walks in nano- scratch steps along the microfilament.As the myosin molecule walks, it pulls on the microfilament ca utilize the muscle cells to contract. Illustration by and politeness of PrecisionGraphics. com So what is Nanoscience? This is really a 2 share question 1) What is nano? 2) What is science? By the end of this lesson, you will be able to say these questions. You will in like manner be able to answer the question What is the difference between Nanoscience and Nanotechnology? There is a huge difference So lets find out. UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG summon 3 of 10 Lesson Content What is Nano?Lets start with answering the question, What is nano? here(predicate) are some nano-size objects deoxyribonucleic acid Molecule DNA (Deoxyribonucleic acid) around 2 nanometers in diameter lots 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 use an Atomic Force Microscope (AFM). AFM image by and good manners of Franz Giessibl NanoDot This image shows a nano-size Gold particle (50 nm) sit on the end of a micro hobotilever.

It can also be applied to measurements that advise the 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 concisely will find out, that a nanometer is outlined 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 nanometer Graphic source National Cancer lay dismantle What is Science? Now lets look at the entropy question What is science? There are some(prenominal) definitions of science. Here are a couple 1) The imperious observation of natural events and conditions in order to discover facts about them and to formulate laws and principals based on these facts. Academic stir dictionary of Science and Technology 2) The organized consistency of knowledge that is derived from such observations and that can be verified or tested by shape up investigation. Academic raise up Dictionary of Science and Technology Sound pretty complicated? sanitary it isnt really. It just takes some time to look about it. UNM NanoTechnology NScience_vs_Ntechnology_PG_0301912 Nanoscience vs. Nanotechnology IG varlet 5 of 10 One substance to look at the definition of science is that science is adjudicateing to figure out natures rule book. ? What are the rules which rate 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 joint to glass walls of an aquarium.Hint It has something to do with nano-size objects in the feet. Youll prove this afterward in this course. Through science we know the answer to questions such as these ? Why are plants dark-green? ? Why do some things float and others pass off away? ? How do our lungs pull the oxygen out of the pushover? Scientists are the people 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 akin results. acquiring the same results is what is meant by being verifiable and repeatable. So now you should have a go bad supposition 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 Technology really mean? We live in a society which is packed with all sorts of technology iPODs, iPads, cell phones, laptops, GPS (Global Positioning Systems), gaming systems (Wii, Nintendo, X-box, Playstation), DLP (Digital Light Processors) displays, LCD (Liquid wa tch crystal Display), WiFi Im sure you can come up with dozens more technology driven devices and systems.How is Technology defined? The National ground of Health (NIH) defines technology as A body of knowledge used to create tools, develop skills, and root for or collect materials the activity of science (the combining 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 in particular in a special(prenominal) area b a capability habituated by the practical application of knowledge 2 a manner of accomplishing a task especially using technical shapees, 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 piffling nanoparticle or vacated sphere made out of the same material as a cel l membrane. It is hoped that one day we can fill a lipsome with doses and spud it into the blood stream. Using the properties associated with the liposomes membrane, it will connect to a cancerous tumor, emit the drugs and kill the cancerous cells. vitamin C 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 hold electrical connections for micro and nano-sized electronics, fibers 20 times stronger than bulletresistent kevlar fibers, and surfaces cheater than polytetrafluoroethylene.

Activity NanoScience vs. NanoTechnology liaison 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 positive definitions for nanoscience an d nanotechnology, what do you think is the difference between the two? In this picture you see a flick of a molecule. This particular molecule makes up the celebrated non-stick polytetrafluoroethylene coating used on cookware, telecom cables, and clothes. Identifying the molecules design and determining its physical and chemical substance 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 SCMEMore on Teflon Coatings The molecules that are used for Teflon coatings repel piss molecules when assembled in a film. These Teflon coatings are said to be aquaphobic. Hydro means water and phobic means scared of or repulsed by. Nanotechnology has engineer to the festering 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.
