introduction background
  • Mechanosynthesis
  • -Creates complex, atomic structures
  • II. Systems of chemical reactions1
  • 1. Combines chemistry and biology
  • 2. Control specific chemical reactions at specific locations
  • III. The NanofactoryCollaboration2
  • 1. 23 researchers from 10 organizations and 4 countries
  • - positionally-controlled diamond mechanosynthesis and diamondoidnanofactory development

Foresight Institute –

Nanofactory Collaboration –


Smart Materials1

1. Any material designed and engineered on the nanometer scale

2. Changes in response to stimili

II. Possible uses

1. Specifically designed drugs that can target certain cells or viruses

2. Self-healing structures2

When exposed to UV light, the polymer disassembles and reforms, patching scratches or cracks.

III. Other uses1:

1. Piezoelectric

2. Memory alloys

3. Temperature responsive materials – changes with temperature

4. Photochromic – changes in response to light

Flexible polymer polydimethylsiloxane (PDMS) that responds to electrical stimili.

Metal Ion Implantation for the Fabrication of Stretchable Electrodes on Elastomers

By Samuel Rosset, MuhamedNiklaus, Philippe Dubois, Herbert R. Shea

  • Replication1
    • Currently theory-based
    • Nanorobots – robots at the nanometer scale
    • A. Idea that they can self-replicate and self-build
    • B.
    • 3. Integration with bacteria - Escherichia coli
    • 4. Nanorobot mutation
    • A. Can be prevented with error-correcting techniques
    • B. Issues over random mutations and deterministic selection




A. Correction of genetic defects


B. Elimination of disease quickly

C. Surgery flesh-welding1

1. Two pieces of chicken flesh are welded together

2. Nanoshells - spherical nanoparticle consisting of a dielectric core which is covered by a thin metallic shell

3. Green liquid containing nanoshells is poured between seams

and welding using infrared laser



Nanorex -


Materials can be created to be light, strong, and inexpensive

- Enable cheaper manufacturing processes

II. Manufacturing would be extremely precise

1. Traditional assembly lines would be reconfigured

2. Every product would be influenced

III. Scarcity of manufactured goods would be nonexistent

- Products, such as food and medicine, can be manufactured rapidly and

in great abundance

Nanotechnology: the coming revolution in manufacturing -

problems risks

Technological Singularity

- Artificial intelligence

Cheaper, more destructive weapons

- Self-replicating Weapons of Mass Destruction

III. Parasitic Nanorobots

1. Self-replicating nanorobots may consume raw materials

without concern

2. Guidelines are established to prevent “free-foraging self-

replicating pseudo-organisms on the Earth's surface”

Foresight Guidelines for Responsible Nanotechnology Development -


The ability to construct literally anything that the laws of physics

permit to exist, with absolute precision

II. Restrictions

1. Costs

2. Developments/Application

3. Control of arbitrary, chemical reactions, microorganisms


1. Weapons

2. Virus and bacteria



Molecular nanotechnology has a very high potential future and widespread applications. Although potentially useful, it can also be potentially dangerous.

It has become appallingly obvious that our technology has exceeded our humanity.
