Nanoparticle: “A particle that is smaller than 100 nanometers (one-billionth of a meter).” A human hair is about 80,000 to 100,000 nanometers wide.
Nanoid robotics, or for short, nanorobotics or nanobotics, is an emerging technology field creating machines or robots whose components are at or near the scale of a nanometer (10 [to the minus 9] meters). More specifically, nanorobotics (as opposed to microrobotics) refers to the nanotechnology engineering discipline of designing and building nanorobots with devices ranging in size from 0.1 to 10 micrometres and constructed of nanoscale or molecular components. The terms nanobot, nanoid, nanite, nanomachine and nanomite have also been used to describe such devices currently under research and development.
Molecular engineering is highly interdisciplinary by nature, encompassing aspects of chemical engineering, materials science, bioengineering, electrical engineering, physics, mechanical engineering, and chemistry. There is also considerable overlap with nanotechnology, in that both are concerned with the behavior of materials on the scale of nanometers or smaller. Given the highly fundamental nature of molecular interactions, there are a plethora of potential application areas, limited perhaps only by one’s imagination and the laws of physics. However, some of the early successes of molecular engineering have come in the fields of immunotherapy, synthetic biology, and printable electronics (see molecular engineering applications) […]

FROM A PUBLISHED PAPER SUGGESTING GRAPHENE TO FIGHT COVID:
Graphene-based materials have been explored extensively for their antimicrobial potentials. Reported studies provided evidence about the broad-spectrum inhibition activity of graphene oxide and its derivatives against bacteria and fungi. In 2014, Sametband et al. reported the antiviral properties of GO and partially reduced sulfonated GO against Herpes Simplex Virus Type-1 (HSV-1) through competitive inhibition mechanism. Similar to cell surface receptor heparan sulfate, GO and rGO-SO3 contain multiple negatively charged groups and thus both moieties compete with each other in binding with HSV-1. Blocking of the virus binding sites with the nanomaterial was the main inhibitory factor to safeguard Vero cells from infection. Ye et al. have compared the antiviral potency of GO, rGO, GO-polyvinylpyrrolidone (PVP) composite, GO-poly(diallyldimethylammonium chloride) (PDDA) composite with precursors graphite (Gt), and graphite oxide (GtO). The study revealed broad-spectrum antiviral activity of GO against Pseudorabies virus (PRV, a DNA virus) and porcine epidemic diarrhea virus […]
What does mainstream research say about nanoparticle DANGERS? A startling idea, right? Look at the open literature.
The first thing you notice while reading published papers on nanotechnology: the language is very dense and very technical. Meaning the public is at a very great distance from what is going on.
This is not a cause for celebration.
