Use of Nanotechnology
bull To study the biological world
ndash Understand processes ndash photoelectric effect ndash how do plants do that
ndash Understanding interactions ndash drugs proteins and side effects
ndash Understanding transplants ndash improve surgery techniques reduce rejection
ndash Understanding processes ndash how do biological systems go from healthy to unhealthy (and vice versa)
To Understand Measure and Study
Understanding and Imitating Nature
Nanoscale Concepts Directly Tie to Biology
Properties Dependent on Size
Nanoscale Concepts Directly Tie to Biology
Priorities of Forces and Interactions
PolymersTwo Variations on a Theme
bull Cross-linked
bull Ringed
Each bond between atoms has a specific strength
A different atom or molecule introduced into this polymer ldquosystemrdquo can form or break bonds dependent upon the relative strengths
Changes in bonds will result in a change in the atomic arrangement (molecular structure) and potentially change the properties of the ldquosystemrdquo
Cross-Linked Polymer
Activity Cross-linked Polymer
Magic Snow (Steve Spangler Science)
Cross Linked Polymer ndash similar to collagen or cellulose ndash the ldquozigzagrdquo of the polymer gives it the elastic property and the cross-linking between zigzags helps keep the structure (stiffness)
Place a small amount of the material in a Petri dish -- Feel it and observe itrsquos physical properties
Using a plastic transfer pipette add some water to the material
Observe what happens
Now feel the resulting material ndash How have the physical properties changed
What do you think happened
Answer The water a dipole molecule interacted with and affected the cross-linking bonds ldquoreleasingrdquo the polymers ndash We changed the atomic arrangement and as a result changed the physical properties of the material
Super Absorbing Polymers (Found in diapers) are ringed type polymers
Surface tension (balanced cohesive and adhesive forces)ldquotrapsrdquo moisture in the ring structureSimilar to the ring blower shape for soap bubbles
Cut a small area of diaperAdd water until saturatedMeasure the amount of water (volume or weight)Determine number of water molecules in the amount absorbedDetermine surface area that could be covered by a 1 atom thick layerie assuming a water molecule has a vol of 4 nm x 4 nm x3nm 5 cc of water would cover 130m x 130m
Other organizations are looking at ways in which nanotechnology can offer improvements in sensitivity or ease by which contamination of food is detected
For example AgroMicron has developed the NanoBioluminescence Detection Spray which contains a luminescent protein that has been engineered to bind to the surface of microbes such as Salmonella and E coli
When bound it emits a visible glow thus allowing easy detection of contaminated food or beverages The more intense the glow is the higher the bacterial contamination
The company aims to market the product under the name BioMark and is currently designing new spray techniques to apply in ocean freight containerized shipping as well as to fight bioterrorism
Nanotechnology Impact on Agriculture ndash Animals and Crops

1959Feynman gives after-dinner talk describing molecular machines building with atomic precision
1974Taniguchi uses term nano-technology in paper on ion-sputter machining
1981STM invented
1985Buckyball discovered
1986AFM invented 1989
IBM logo spelled in individual atoms
1997First company founded Zyvex
Nanotechnology has been primarily driven by the semiconductor industry and the
need for smaller faster and more efficient chips
Packing more and more transistors onto a single chip made many aspects of modern
life possible
HISTORY OF NANOTECHNOLOGY
Nanotechnology ishellip
The ability to observe image study measure and manipulate at the molecular and atomic scale
Atomic (electronic) structure

Use of Nanotechnology
bull To study the biological world
ndash Understand processes ndash photoelectric effect ndash how do plants do that
ndash Understanding interactions ndash drugs proteins and side effects
ndash Understanding transplants ndash improve surgery techniques reduce rejection
ndash Understanding processes ndash how do biological systems go from healthy to unhealthy (and vice versa)
To Understand Measure and Study
Understanding and Imitating Nature
Nanoscale Concepts Directly Tie to Biology
Properties Dependent on Size
Nanoscale Concepts Directly Tie to Biology
Priorities of Forces and Interactions
PolymersTwo Variations on a Theme
bull Cross-linked
bull Ringed
Each bond between atoms has a specific strength
A different atom or molecule introduced into this polymer ldquosystemrdquo can form or break bonds dependent upon the relative strengths
Changes in bonds will result in a change in the atomic arrangement (molecular structure) and potentially change the properties of the ldquosystemrdquo
Cross-Linked Polymer
Activity Cross-linked Polymer
Magic Snow (Steve Spangler Science)
Cross Linked Polymer ndash similar to collagen or cellulose ndash the ldquozigzagrdquo of the polymer gives it the elastic property and the cross-linking between zigzags helps keep the structure (stiffness)
Place a small amount of the material in a Petri dish -- Feel it and observe itrsquos physical properties
Using a plastic transfer pipette add some water to the material
Observe what happens
Now feel the resulting material ndash How have the physical properties changed
What do you think happened
Answer The water a dipole molecule interacted with and affected the cross-linking bonds ldquoreleasingrdquo the polymers ndash We changed the atomic arrangement and as a result changed the physical properties of the material
Super Absorbing Polymers (Found in diapers) are ringed type polymers
Surface tension (balanced cohesive and adhesive forces)ldquotrapsrdquo moisture in the ring structureSimilar to the ring blower shape for soap bubbles
Cut a small area of diaperAdd water until saturatedMeasure the amount of water (volume or weight)Determine number of water molecules in the amount absorbedDetermine surface area that could be covered by a 1 atom thick layerie assuming a water molecule has a vol of 4 nm x 4 nm x3nm 5 cc of water would cover 130m x 130m
Other organizations are looking at ways in which nanotechnology can offer improvements in sensitivity or ease by which contamination of food is detected
For example AgroMicron has developed the NanoBioluminescence Detection Spray which contains a luminescent protein that has been engineered to bind to the surface of microbes such as Salmonella and E coli
When bound it emits a visible glow thus allowing easy detection of contaminated food or beverages The more intense the glow is the higher the bacterial contamination
The company aims to market the product under the name BioMark and is currently designing new spray techniques to apply in ocean freight containerized shipping as well as to fight bioterrorism

Use of Nanotechnology
bull To study the biological world
ndash Understand processes ndash photoelectric effect ndash how do plants do that
ndash Understanding interactions ndash drugs proteins and side effects
ndash Understanding transplants ndash improve surgery techniques reduce rejection
ndash Understanding processes ndash how do biological systems go from healthy to unhealthy (and vice versa)
To Understand Measure and Study
Understanding and Imitating Nature
Nanoscale Concepts Directly Tie to Biology
Properties Dependent on Size
Nanoscale Concepts Directly Tie to Biology
Priorities of Forces and Interactions
PolymersTwo Variations on a Theme
bull Cross-linked
bull Ringed
Each bond between atoms has a specific strength
A different atom or molecule introduced into this polymer ldquosystemrdquo can form or break bonds dependent upon the relative strengths
Changes in bonds will result in a change in the atomic arrangement (molecular structure) and potentially change the properties of the ldquosystemrdquo
Cross-Linked Polymer
Activity Cross-linked Polymer
Magic Snow (Steve Spangler Science)
Cross Linked Polymer ndash similar to collagen or cellulose ndash the ldquozigzagrdquo of the polymer gives it the elastic property and the cross-linking between zigzags helps keep the structure (stiffness)
Place a small amount of the material in a Petri dish -- Feel it and observe itrsquos physical properties
Using a plastic transfer pipette add some water to the material
Observe what happens
Now feel the resulting material ndash How have the physical properties changed
What do you think happened
Answer The water a dipole molecule interacted with and affected the cross-linking bonds ldquoreleasingrdquo the polymers ndash We changed the atomic arrangement and as a result changed the physical properties of the material
Super Absorbing Polymers (Found in diapers) are ringed type polymers
Surface tension (balanced cohesive and adhesive forces)ldquotrapsrdquo moisture in the ring structureSimilar to the ring blower shape for soap bubbles
Cut a small area of diaperAdd water until saturatedMeasure the amount of water (volume or weight)Determine number of water molecules in the amount absorbedDetermine surface area that could be covered by a 1 atom thick layerie assuming a water molecule has a vol of 4 nm x 4 nm x3nm 5 cc of water would cover 130m x 130m
Other organizations are looking at ways in which nanotechnology can offer improvements in sensitivity or ease by which contamination of food is detected
For example AgroMicron has developed the NanoBioluminescence Detection Spray which contains a luminescent protein that has been engineered to bind to the surface of microbes such as Salmonella and E coli
When bound it emits a visible glow thus allowing easy detection of contaminated food or beverages The more intense the glow is the higher the bacterial contamination
The company aims to market the product under the name BioMark and is currently designing new spray techniques to apply in ocean freight containerized shipping as well as to fight bioterrorism
Nanotechnology Impact on Agriculture ndash Animals and Crops
