Bacteria Hunter

In this article I try to present and explain new version of active medicine nanorobot design, which based on Robert Freitas study of nanorobot, used for cleaning bloodstream from bacteria, viruses and fungus.

In this article I try to present and explain new version of active medicine nanorobot design, which based on Robert Freitas study of nanorobot, used for cleaning bloodstream from bacteria, viruses and fungus.

Worm – nanorobotic device, capable of removing hazardous fungi and microorganisms from human bloodstream. This is alternate device for Robert Freitas microbivores and with simple construction. Freitas microbivore must move collected bacteria with set of telescopic grapples, but Worm doesn’t require them.

Worm movements based on modern theories about nano- and microsystems movements in liquid environments. Blood is such environment, so worm nanodevice it will swim through blood, using unique driving force – rotating set of mills, consist of active nanocapsules. They movements cause “blood pumping”, co nanorobot can move, use reactive force from liquid spray, moved by rotating tracks.

Worm Nanorobot – perspective view

Main principle of this device based on usual mills design. So we can see array of nanospheres, from which mill consist of. These nanospheres are sophisticated nanomechanical systems. Each contains set of molecular binding sites, nanomechanical components, simple computer and rotate mechanism. All surface of these nanosphere covered by specific binding sites, which imitate natural protein markers of hazardous bacteria and fungus. So, when nanosphere meets with “foreign body”, it usually binds on it surface.

Bacteria attachment at nanosphere surface

Worm detailed description is very complex work, that’s why in this article I describe basics of this nanodevice’s construction. Worm can be separated on two areas: inner and external. In external area nanosphere mills collect bacteria and fungi. Set of external panels pump on glucose energy source, water and pump out digested bacteria nutrients.

Inner area consist of reversive mills, which load collected bacteria into nanorobot digest chamber. Nanospheres simple rotates and upload bacteria inside nanorobot.

Schematic Worm description: nanospheres releases bacteria

Here, as in Robert Freitas design, a bacterium smashes by rotating screw mechanism and, after this, digested by various enzymes to primitive organics. Than these liquid mass pumped out with special piston chambers into blood.

How we can see, proposed worm design can collect and digest more microorganisms than microbivore. It can move in blood, so it will multiply number of collected bacteria.

Nanorobot in bloodstream can collect bacteria and fungus

Worm can also crawl on the tissue surface, so I can imagine worms, crawling on vein’s surface to clean out atherosclerosis conglomeration. Worm will be constructed from diamondoid with high precision molecular assembling technology.

Now for nanorobotic device, called Worm, available animation, which can show, how exactly device can move, collect bacteria and crawl on surface of capillaries and veins.

Worm tracks technology allows fully reprogrammable binding sites, which can make Worm multipurpose device – it can collect not only bacteria or viruses, but toxic enzyme too.
