For simplicity, let's pretend these are well designed nanobots that don't outright kill their host by blood clots or accidentally ripping holes in capillaries. So let's pretend these great scientists already killed a bunch of small woodland laboratory creatures and got those little issues figured out relatively early on. We'll assume these nanobots are the ...

Why, glucose and oxygen! These have significant benefits: Fuel cells are already available technology, so you can get electricity from pretty much anything that would normally burn. Should be possible to adapt it to work on glucose all right You already want oxygen and glucose in blood. Both are pretty easy to supplement. No real need to store energy, as ...

There are two kinds of summoning, when you really get down to it. There's the summoning where the summoned wants to be summoned, and there is the summoning where the summoned is compelled to be summoned. Define your demon, and its behaviors, and you define how to summon it. It may want to be summoned, in which case this is extremely easy to explain. The ...

Piezoelectricity Since plasticity is a required function of these nanobots and the heart is going to be compressing them at a steady rate, piezoelectricity is your very best friend here. As it's generated very simply, there are no moving parts required, no batteries to charge, no complex chemicals, all you have to do is stay alive and they'll keep running, ...

Graphene is what you're looking for. With a tensile strength of 130000 MPa, it has (IIRC) the highest tensile strength in the world. So lets make a wire-thin sword! I envision it to probably end up looking something like this: >----------------------------------------------<| ||||||| | ...

Since all the other ones I thought of have already been used, I had to go find something else. The one I was going to use was piezoelectricity (though I didn't know what it was called!) And I think that would be the most useful for machines of this size. However, my contribution to this would be Inductive charging. It uses an electromagnetic field ...

Your ruleset has put you in a corner. You state that they can disassemble "ANY organic/nonorganic compound into their core components." The typical definition of "nonorganic" is "any compound which is not organic." By logic, that says your nanomachines can disassemble "ANY compound into its core components." Thus, by straightforward logic, no material is ...

Well, we can't do it now so the only answer we have is 'more than we have now'. Alright, this isn't strictly true, insofar as we can cryogenically freeze embryos and the like, and we can then thaw them and bring them to term so depending on your definition of 'someone', arguably the minimum technology someone needs is the ability to create and maintain ...

A Programmed Feature: This idea is inspired by Willk's answer, though there have been other good ideas in the thread. It's a deliberate design choice by the long ago designers of the craft. Meant to help highlight and locate damaged components - the nanites activate a phosphorescent effect whenever chunks of the ship become separated from each other. ...

You should not think of a nanobot like a 'eating'-animal or something. This would be a big problem, due they only could handle molecules and cells wich are smaller than they are, plus they need additional size for some extracting or cutting mechanics to get the molecules/cells off whatever they're attached to. Better think of nanobots like enzymes. They ...

Anything that is programmable, is hack-able. The first thing to do would be to hack the nanobots. Also 'tinfoil' hats come in here, block the incoming and outgoing signals and you have some control and privacy. The most likely scenario would be for the resistance to find a 'kill' switch for the nanobots so they become inert or permanently shut down. That ...

Let me be blunt A microscopic LED is entirely believable. I'd ignore all the explanations of why or why not and roll with the idea. Now the answer LEDs are diodes that emit light when they're in their operational state. Fundamentally, when you ignore the mechanics of miniturization (fabrication), your limitations are three-fold. First, even at magical ...

Daiquiri cryonics This is my favorite low tech method. Blood sugar and blood alcohol (and also acetone) are driven up in tandem. Way up. The person does not die of diabetic coma because her blood alcohol is so high, and does not die of alcohol poisoning because she is so cold that brain metabolism is slowed. You want the body no colder than the freezing ...

You need a trigger word. Right now, I can summon a big red round demon with the trigger phrase "hey Siri." My parents summon a materialistic demon with the trigger word "Alexa." Your demon bots (and nanites, etc) network with each other and if the summoning is done within earshot of any one of them, the message will go to the right demon who can respond, ...

One starting point would be to ask what objects have survived for 10000 years in reality? One possible survival would be artwork and jewelry. In particular I am thinking of artwork that was carved into durable materials like stone or bone or glass. Even just painting inside a cave can last 10000 years or more. Since these objects are not themselves "...

You can also use the great power of physics. A high intensity electromagnetic pulse (EMP) could shutdown every nanite in a given area. This could be used. An atomic bomb exploding safely away could destroy nanites of a entire city. You could build a EMP generator only for you, with "few" use of electricity, an using accessible material to everyone. You can ...

Really it depends on how they work. Software Injecting a software virus to disrupt the network might work if they are reprogrammable. Rival Goo Add your own nanomachines that take apart the first ones and rebuild them to themselves then shutdown. Energy Weapons Directed energy weapons or similar might be used to destroy them without presenting them ...

Keep in mind that archaeology can learn as much by what is missing as by what is present. In the UK we have a stone-age village from thousands of years ago that has been recreated by analyzing the holes in the ground that the huts and their support posts made. These houses were made completely from wood but the evidence lay preserved in the ground until ...

You're going to trigger a cultural problem, that of the importance of being seen to do over actually doing. Let's consider two people One is a young man of no great resource, he helps little old ladies across the road, works in a soup kitchen during his holidays and helps his elderly neighbours with chores they can't handle any more. There's no question ...

Yes, it's possible to have LED displays with microscopic pixels. 3.74 μm qualifies as microscopic, I think. The JD4704 is currently the world’s first 0.7”, color sequential, 4K2K LCoS microdisplay comprised of over 10 million of the world’s smallest all-digital pixels, with a 3.74 x 3.74 μm pixel size.

I'm wishing I'd kept up my fluid dynamics now. A significant quantity could start affecting the viscosity of your blood which would place extra strain on your heart, making the long term benefits questionable. Read the bit about blood viscoelasticity. If your nano-bots don't deform in a similar manner to red blood cells you could have some very interesting ...

You'd use it as a bolas Wind it up, let it go and watch your enemies fall like grass before the scythe... Obviously, you have to wear a hat and take care not to decapitate your angry-looking horse mid-gallop...

TL;DR EMPs probably won't work and simple magnets won't help on silicon machines. But offering honey-pot-counter-bots that attach to the offender and render them useless or use blood transfusion and a cleaning mechanism might work. Reality Check Professor Bradley Nelson of ETH Zürich managed to build a nanomachine that could be remote controlled and moved ...

Mental rewiring -- I was going to type up an answer for this, but I got this uncontrollable urge to go out and get this 10,000% APR large loan from this obscure Moldovan company. I then for some unfathomable reason purchased 10,000 dildos with the loan money. Ransomware - Your organs will shut down at the rate of 1 every 6 hours unless this much money is ...

The existence of replicators means you don't need most other tools. They would carry a stock of elements to use with the replicator. If they decide they need ropes, they replicate ropes, etc. Their main provision would be information. Things they don't need to know in normal situation, such as many different ways of making tools and materials with ...

Interestingly, in unix land, we call any program running autonomously, a daemon. To interact with these daemon, one must know it's name, the commands available, the method of delivery of those commands, and the format of any data you wish to be processed. "Hey Siri, tell me tomorrow's weather at my location" sounds innocuous enough, but imagine if it still ...

Let's distinguish between nanomachines (which are self-contained structures on the nano scale) and nanodevices (which could be just parts in a larger machine). EMP weapons work by inducing damaging voltage in electric conductors. A nanomachine is very very small; let's say that the EMP comes with a humongous 100 kV/m. (For comparison, the insulating ability ...

N.B. The question was edited The question was edited to disallow this specifically. It’s good to keep as a reference though, since the Q and other As will need to refer to the distinction between microbots and full molecular assembly. original answer There is no real problem. Instead of thinking about assembling everything from scratch or disassembling ...

This makes no sense. Artificial DNA has the same basic structure as natural DNA, to be able to interact with enzymes that produce protein. No matter if it's synthetic or not, it will function just the same, look just the same. In no way DNA can encode "confused blur between organic and mechanic." - all it encodes is protein and control instructions. So ...

There's nothing we currently can do that's "better" to what "mother nature" conceived. We can build "bigger", "stronger", "faster" subsystems: nothing of what we built to date is self-sustaining, let alone self-replicating. We are speaking about building self-sufficient and self-replicating factories for planet colonization, but that's speculation never ...
