Photonics Center NSF REU and RET INM Introduction to the Nanoscale Prof. Helen Fawcett, ME 1
Photonics Center NSF REU and RET INM What is a nanometer? Scale of measure to the -9 power Fingernails grow at 1 nm/second Cut a bacterium 1000x 2
Photonics Center NSF REU and RET INM What is a nanometer? 10-9 meters One billion nanometers in a meter One million times smaller than the head of a pin A thousand times smaller than a bacterium 10 Hydrogen atoms lined up A sugar molecule Your fingernails grow at 1 nm/second: here s a lab experiment to try: http://neurodojo.blogspot.com/2012/03/nano-scale- fingernails-and-using.html 3
Photonics Center NSF REU and RET INM How can we compare that to objects we can see An atom is 0.1 to 0.5 nm in diameter DNA molecules are 2.5 nm wide Virus is about 100 nm wide, bacterium 1000 nm Width of human hair 100,000 nm Head of a pin a million nanometers wide Adult male 2 meters (6 ft. 5 inches) is 2 billion nanometers tall Source:http://nanosense.sri.com/activities/sizematters/si zeandscale/SM_Lesson2Student.pdf 4
Photonics Center NSF REU and RET INM Relative Sizes Imagine an ant (2 3 cm) compared to you, an ant is about 1000x smaller than you Imagine an ant compared to an amoeba (1 um), the amoeba is 1000x smaller than the ant A nanometer is 1000x smaller than an amoeba A person would have to shrink themselves down by a factor of 1000 three times to be the size of a nanometer 5
Photonics Center NSF REU and RET INM What is Nanotechnology? Making things to nanoscale Technology using science to solve problems Technology with smallest feature sizes of 10 nm 6
Photonics Center NSF REU and RET INM What is Nanotechnology? http://www.omninano.org/ Nanotechnology is an interdisciplinary field that integrates all aspects of sciences and engineering manipulating nanomaterials Quantum Dots 1 50 nm diameter Carbon Nanotubes 1 3 nm in diameter Graphene 1 carbon atom thick 7
Photonics Center NSF REU and RET INM What is Integrated Nanotechnology? Chemistry, biology, physics of nanotechnology integrated with engineering An integrated technology that is collaborative between the fields Using nanotechnology in standard macroscale/mesoscale settings 8
