Quantum_Conundrum
Here I am discussing hypothetical (primarily) medical application nano-robots of approximately the size of a human blood cell(57-101 cubic nanometers). There would also be potentially various industrial uses.



Firstly we must realize that the very existence of life, particularly the CELL, is proof that such a highly complex nano-scale machine is theoretically both plausible and possible to construct. Even at this tiny scale, the cell, depending on what type it is, has locomotion, it has energy supplies, it has "programming" in the form of DNA, it has mitochondria, Ribosomes, the nucleous, transport mechanisms for water and electrons, etc. All of these are analogous in some way to systems we might expect to find in both a microscopic and macroscopic robot.


Now something I began to consider as I thought more and more about the concept of medical nano-robots is the idea that it would be very nice for the nano-robot to get its energy from the biology of the patient, rather than any sort of battery or whatever. While this technically makes them parasitic, they are designed for a very short lifetime and used only for simple diagnostics or specific cell, tissue, and organ repair, or for the killing of invading pathogens(virus, bacteria, cancerous cells, etc.)

Yes. I was only part way through writing what I was going to write yesterday.

I will continue today I think.

Swarming autonomous miniature robots.

Called Kilobots, the quarter-sized bug-like devices scuttle around on three toothpick-like legs, interacting and coordinating their own behavior as a team. A June 2011 Harvard Technical Report demonstrated a collective of 25 machines implementing swarming behaviors such as foraging, formation control, and synchronization.

Maybe in the future a variation will be the crabbot for manicuring your pubes.

Yes, well, you are probably referring to the Borg, in which case the original designers of the technology went to far and the technology went haywire, producing a largely emotionless parasitic collective cybernetic life form which preys on other civilizations.


I hope that humans are smarter than this, and develop these technologies in a safe and moral manner as they become possible.

We are already doing primitive middle ground steps, as I point out, through GM and also through the Prostate cancer vaccine, which modifies a patients own white blood cells to destroy the cancer, and other approaches.

These are nano tech, but they are not yet the classic sci fi "Feynman's room at the bottom" nano-tech, at least not yet in most fields, and certainly not the self assembling or self replicating kind in most fields.

But chemists and materials scientists are learning to combine materials in ways previously not imagined to create extremely small systems and produce other useful machines; sensors, emitters, various actuators, transistors, etc.

MRSA adapts to antibiotics, but if you could make a nano-particle or a nano-machine that could mechanically grind, pierce, or burn the bacteria, it might not be able to adapt to that at all.

For example, since it was discovered that MRSA doesn't grow on copper plated surfaces, it might be useful to attach a copper atom or copper compound to a normal antibiotic molecule and see if it penetrates the MRSA more efficiently, or provides any other anti-microbial benefits.

Of course, this would require some chemical genius or some form of nano-assembly to make this compound in a quantity large enough to do trials...

Sorry to bring the news to you... Man as a collective is not "smart" nor "moralic"...

When we live in a large enough society, empaty is exchanged with the hunt for money and power...

For example (it is out of nanotechnology, but draws the line for the humanity behaviour)

U.S (and it's military) is developing "robot" warriors for military use, (no it is not SciFi - they have prototypes and it is no secrets either), the goal for that robot should finally be that it is good enough to kill enemy soldiers on it's own...

Now... why should (wrong) politician and military for example stop there, why not develop nano"bots" if they could, that could gain control of an enemy army and control it... the "right" (if any) military and politician would be forced to do the same...

It is not entirely impossible to control a brain, there is a parasitic organism that takes control of an Ant and makes it a zombie... I guess our brain is more complex... but there is nothing scientist could not do with enogh time...

I see nobody has commented on my idea of attaching a copper compound to an existing anti-biotic in hopes of penetrating an otherwise resistant/immune bacteria.


Are you baffled by the simplicity? The genius?

But why no trials?

Surely somebody can figure this out well enough.

That's 'cause anyone with a brain cell might've chosen a silver ligand, dummköpfe.

Nanorobotics plays vital role in the the development of efficient robot.It uses nano components and there objects to build the structure of robots.This technology has incredible application in the field of science.
Fiels of application:
1) To cure skin diseases,a cream containing nanorobots are used.
2)A mouthwash full of smart nanomachine could identify and destroy pathogenic bacteria while allowing the harmless flora of the mouth to flourish in a healthy ecosystem.
3)Medical nanodevice could augment immune system by finding and disabling unwanted bacteria and viruses.
