History
• In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules, we just do not have the ability to do so yet.
•Said we should be able to create machines that can arrange or rearrange atoms and molecules however we want

How small can we go?
Since the 1970’s, computers and their components have decreased in size at least every 6 months

What is Nanotechnology?
Improvement of all human biological systems from the molecular level
Preserving and improving human health using molecular tools
Employment of molecular machine systems to address medical problems

Biotechnology
The application of the principles and practices of engineering and technology to the life sciences
Limiting and delivering stem cells
Gene Therapy
![Page 7: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/7.jpg)
Surgery
Absolute noninvasive surgery
No risk of scars or outside influence
Doctor never even has to actually touch the patient
Construct new, or repair organs from the inside
![Page 8: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/8.jpg)
Surgery cont.
Some nanomachines used as “white blood cells”
Viruses and bacteria cannot develop any kind of immunity
![Page 9: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/9.jpg)
Drugs Can be administered
through a regular syringe
Thousands can be administered at one time, for one, or many treatments
Can construct, or deconstruct molecules to treat, or destroy

Diagnostics
Diagnostic nanobots can take measurements, track certain cells, bacteria, etc.
Transmit data back to doctors Nanocameras take images of healthy
and/or damaged cells Can determine if other nanobots present
should act

Medical Robots Can be effective in almost any part of human
body
Mouthwash
Skin Cream
Immune System
Directed targeting of infected or diseased areas

Ethical Issues
Not enough extensive work yet
Nanobots may be so small they can pass through membranes within the body
Blood-brain barrier
Not known if nanobots toxic to humans
![Page 13: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/13.jpg)
Issues cont.
Long term risks
Self-Replication
Gray-goo scenario
Invisible tracking and recording devices
Bioterrorism
![Page 14: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/14.jpg)
Issues cont.
How much will it cost?
Separation of those who can afford nanomedicine and who cannot?
Gene therapy
Altering DNA in unborn children
![Page 15: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/15.jpg)
Transhumanism Transition from normal human,
to one with enhanced abilities due to genetic enhancements
Next step in human evolution?
Longer life spans – overpopulation
Eliminate disease, but eliminating humanity?
![Page 16: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/16.jpg)
And in Conclusion…
Overall positive benefits would help humans in eliminating disease and better health
Negatives could be catastrophic, not only to oneself, but to the world
![Page 17: Microscopic Ethics By: Matthew Sparks. History In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules,](https://reader035.vdocuments.us/reader035/viewer/2022062714/56649d2f5503460f94a07693/html5/thumbnails/17.jpg)
What do you think?
Better for humanity, or a downfall? Would there still be a distinction
between man and machine? Or another category?
Could nanotechnology be controlled to only pertain to the good aspects?
Who should be the ones that receive the nanomedicinal treatments?
