Ions and metasurfaces are the new tools for robotics.

The new metasurfaces and ion channels turn information technology and nanomechanics forever. The photonic or photon-reacting and interacting metasurfaces make it possible to create devices that can operate independently in complex situations. 

Those photonic-controlled devices can make things like highly advanced morphing systems possible. In nanotechnology, it's essential to control systems. That is smaller than some molecules. And the metasurfaces are one thing that makes that system possible. When we think about systems like cars and robots that can change their shape, we must realize one thing. 

Those morphing surfaces will be created by nanomachines that act as the morphing neural network. Those small robots can take any form that they ordered. The system can interact with outsider observers like small drones that can tell that small, soundbite size nanorobot swarm how they should move to take a certain form. That thing means that the AI-controlled system can take any shape that it sees. The drone can make the 3D scanned image, and then order those nanorobots to take it. 

In some futuristic visions of the future, the data travels in the organic network. Those systems can be neurons or some hybrid cells. The long threads transport information like neurons. Those systems can transport information between those neurons by using the lion channels. Those ion channels make it possible for information to travel most of the time in chemical form. When that neurotransmitter reaches that neurotransmitter, it sends an electric impulse to the microchip that decodes the message. 

Ion channels are interesting. Those channels can form the ion superhighways that can make new ultra-secured data transmission possible. In those nanorobots, the system can have a small tube that transfers those ions from one place to another. The ion can transport information as well as electrons or photons.  There are multiple ways to make that data transportation.

One is to use two ion channels and shoot ions through them. The ion channel one is the one in the binary system. And the ion channel two is the zero in the binary system. Those ion channels can be thousands of kilometers long. And that allows the system to transport ions over long distances. 

In some Sci-fi-Books that kind of system can also transport antimatter like positrons and anti-protons into the wanted point. This kind of system can installed in the robot bug. The robot bug transports those antimatter particles to the wanted point in the magnetic chamber, that puts them to flow. 

That denies antimatter contact with the walls of that chamber. Then the robot injects antiparticles through that ion accelerator or ion proboscis. That kind of weapon would be extremely horrible. And one of them can destroy even warships. The antimatter energy level is so high, that a gram of that matter turns the entire Earth into a molecular cloud. 

The ion-based information transport system is one of the versions of ultra-secured data transmission. The idea is that. The system can deny the outsider observer. To see ion. If the outsider harms the ion channel that thing is seen in control rooms. The receiving system must require the energy level and speed of ions to be at a certain level. Those things tell that ion is part of the message. 

The ion channel is also a vacuum, and if somebody wants to steal information, that launches the pressure sensor and denies the ion flow. The ion systems might not look as effective and wonderful as photonic systems. But they can interact between living neurons or organic microchips and regular, non-organic systems. In that system, the microchip transports information to the neuron cell's ion channel using the ions.

The polaritons are the tools for nano-size photonics.

"Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in the form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Photonics is closely related to quantum electronics, where quantum electronics deals with the theoretical part of it while photonics deal with its engineering applications. " (Wikipedia, Photonics) 

Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s." (Wikipedia, Photonics) 

The first solution that used photonics was an optical data cable. Those cables are still one of the most secure data transmission systems. It's possible that the system can use outside optical fibers to send so-called empty signals. If somebody changes the form fiber or cuts it the system detects it. Then it can report that anomaly in wavelength to the system supervisors. 


In that system, data travels in an inner optical fiber. That makes outsiders hard to see the data flow.  If somebody wants to eavesdrop on that data. The spy must damage or turn the outside optical fibers. 


And the system notices that. Similar systems can detect things like earthquakes. The movements on the ground stretch and change the route of the light. And that allows observers to see if something or somebody moves the optical cable.

Modern photonics is the tool that makes much more than just transport data.  The high-power computers make it possible to manipulate nano-optical layers. Those layers can transfer photons into wanted directions. The ability to remove reflection from layers is the ultimate tool for stealth technology. And the same thing can make quantum computers more effective. Without reflection, there are not-so-strong artifact effects that disturb the quantum entanglement. 

The ability to create quasiparticles is a great advance in photonics. The quasiparticles can create energy potholes or energy dumps that allow energy and photons to travel in them. The energy potholes in material pull it in together. The quasiparticle can aim photons in the desired direction. And that can make it possible to create the switches and routers for the photonic microchips. 

"In physics, polaritons are bosonic quasiparticles resulting from strong coupling of electromagnetic waves (photon) with an electric or magnetic dipole-carrying excitation (state) of solid or liquid matter (such as a phonon, plasmon, or an exciton).[example needed] Polaritons describe the crossing of the dispersion of light with any interacting resonance."
