The MMORPG Anarchy Online (launched 2001) is set on a planet with well-developed nanotechnology, which generally is used as magic in fantasy-themed games. In Metal Gear Solid (1998) the protagonist got nanomachines to supply and administer adrenalin, nutrients, sugar, nootropics, and benzedrine and to recharge a Codec's battery.
Nanoparticles are distinguished from microparticles (1-1000 μm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects [3] or electric properties.
However, human skin is an effective barrier to ZnO nanoparticles, for example, when used as a sunscreen, unless abrasions occur. ZnO nanoparticles may enter the system from accidental ingestion of small quantities when putting on sunscreen. When sunscreen is washed off, the ZnO nanoparticles can leach into runoff water and travel up the food ...
Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, [1] [2] a scenario that has been called ecophagy (the literal consumption of the ecosystem). [3]
The reason gold nanoparticles are used is due to their vivid optical properties which are controlled by their size, geometry, and their surface plasmons. Gold nanoparticles (such as AuNPs) have the benefit of being biocompatible and the flexibility to have multiple different molecules, and fundamental materials, attached to their shell (almost ...
Diamond nanoparticles have the potential to be used in myriad biological applications and due to their unique properties such as inertness and hardness, nanodiamonds may prove to be a better alternative to the traditional nanomaterials currently utilized to carry drugs, coat implantable materials, and synthesize biosensors and biomedical robots ...
Nanites are used in a number of episodes in the television series Travelers. They be programmed and injected into injured people to perform repairs, and first appear in season 1. Nanites also feature in the Rise of Iron 2016 expansion for the video game Destiny in which SIVA, a self-replicating nanotechnology is used as a weapon.
