quite a few clients have sent me this video and many like it, which make a lot of claims about nanotechnology and hydrogel being observed in the blood. I am pretty skeptical of these claims for the following reason

you can't see nanotechnology in light microscopy smaller than 500 nanometers (0.5 micrometers), and that's the theoretical boundary

Most viruses for example vary in diameter from 20 nanometers 400 nm, observing anything this size is beyond the capabilities of light.

(noteworthy exception in the size of viruses would be Ebola viruses can have lengths up to 14,000 nanometers (14 micrometers) with a diameter of 80 nanometers)

I would point out that the microscopy done in this video is phase contrast light microscopy which is similar what I use. This is on a Micrometer scale, not Nanometer scale. so anything you would see in this sample is 1000x too large to be nano technology.

Hopefully this helps, I don't think everything in the video is inaccurate but a lot of the claims don't make sense....
