How dangerous can microplastics be?

"Plastics affect every aspect of the Earth system, from climate change to biodiversity, due to the thousands of chemicals in their life cycle, impacting environmental and human health. A new study calls for understanding plastics pollution beyond waste management, using a planetary boundaries framework to highlight plastics’ global, interconnected impacts." (ScitechDaily, Not As Harmless as Scientists Thought: Plastics Are Threatening Earth’s Stability)

Microplastics are small pieces of plastics that are filling oceans. Those things form in things like the cosmetic industry. The reason why those things are used is that they should not be poisonous. The plastic itself is not poisonous. But when we think about the microplastics. Those things act like nanomachines. When things like krill eat some algae those microplastics get in their body. 

The microplastics are very dangerous to bacteria. If bacteria eat those small plastic bites that can cause internal damage to its structure. Sometimes some researchers introduced that some cancer medicines will replaced by microplastic nanomachines. The problem was how to remove those things from the body. 

If those microplastics are covered using nutrients that certain bacteria or cancer cells eat, those small plastic bites can slip into those cells and destroy their internal structure. The nano- and microplastics can slip into the cells and even fill them. 

There those small plastic bites travel in the food chain. And finally, they return to the human saucer and our food. The thing that makes microplastics dangerous is that it's possible that they get into cells. In those cases, the cells can damaged or even die if those microplastics harm their internal structures. 

There are many points where the microplastic can touch and cause damage. Those microplastics can clog the pipelines in cell organs. That causes errors in the cell's normal functions.  The microplastic can damage the cell's mitochondria or even destroy them. Or it can cause damage to the cell's nucleus. 

Or they can jam the cell's ion pumps. The string- or stick-shaped microplastic can make holes in the cell's protein shell or it can stuck into the ion pump. That keeps the ion pump open all the time. Microplastics can damage even big animal embryos if they get into a morula. But microplastics can endanger things like plankton. And through plankton, those small plastic bites can go into the human body.

The triangular-shape diatom and it work as the nano-sized UAV

The triangular-shape diatom and it work as the nano-sized UAV

What if we could just grow the core of nano-machine? That thing would make creating those things easier. And if we are thinking about the triangular-shaped diatoms, we could just empty them and install the driving system in those cores.

When we are thinking about the triangular-shaped diatom, that thing would be the perfect body for micro-or nano-UAV. In this case, the diatom would be blown empty, and then the ventilation and other needed things would install to that core. The nano-sized UAV would use the external power source, like high-power radio impulses to get the electricity. And the needed power for flying would be made by using the small-sized pump or electric arc.

The airflow below would hang that thing on air, and then other tubes with ventilation would be used to adjust the direction, where this small air vehicle would move. The miniaturized microchip would control that extreme small ventilation, and it would make that thing good maneuverable. The location of that thing would be getting by using the RFID chip, which is making it easy for locating that nano-UAV.

That means that those robots can be dropped to the sea, and they can be used to observe the flows underwater. And as I have written many times before this kind of system might be used as well in the underwater and airborne conditions. This means that the small robots can look at things also in every groove on the bottom and stones for looking for things like algae or pollution. They could also operate in the blood veins in the body of living organisms and take samples of the cells, what they can find in there.

But those nano-sized drones might also have military missions. and they could be the effective weapons against the enemy if they are used as the artificial Sandstorm

The artificial intelligence, what controlled system must know the location of that nano-sized aerial vehicle, and in fact, it can be used as the smart bullet, what is driven to impact the enemy, and that system can be used against enemy troops as the artificial Sandstorm, what turns enemy to sand. That kind of storm of nano-machines can crush the enemy army in seconds.

And they can fly in the turbines of aircraft and make holes to fuel canisters. If they are loaded with high voltage of electricity, that makes them the ability to create a magnetic storm, which can damage electronics and deny communication. But those miniature UAVs might have more missions than we ever want to know.

Nano-sized aerial robots can be equipped with the non-optical camera and maybe there is possible to install the small microphone in some of those nano-UAVs. That means that those systems might be the most effective recon planes, what mankind has ever created. Even one of those nano-UAVs have only one sensor, they can be delivered millions in the operational area.

And they would operate as the cloud. They can have miniaturized electronic mission packs, and nano-UAV:s can deliver data to own intelligence. Those systems are almost impossible to locate, but if the cloud of those UAVs has been noticed, the EMP-weapon can drop them from the skies, or the ECM just denies them communication between together in the cloud.
