Nanotechnology

2. A Greek word meaning dwarf; one billionth
3. The movement of molecules in a random fashion to create an evenly concentrated environment
5. A material capable of interacting with living tissues
7. A film created when microorganisms stick to each other and often also to a surface
8. Semiconducting nanoparticles that are able to confine electrons in small, discrete spaces
9. The process of a molecule being absorbed or soaked up into another region or part, such as a drug being soaked up by the digestive tract into the bloodstream
12. A substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource;may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values
14. A unit of measurement often used to express dimensions on an atomic scale
15. Emission of light by a substance that absorbs light by electromagnetic radiation of a different wavelength
17. The property of a substance to dissolve into solution
19. A particle, usually referring to inorganic material, that measures between 1 and 100 nanometers in size, surrounded by a layer of ions as well as inorganic and organic molecules
20. The merger of nanotechnology and biology: using nanotechnology to further study the field of biology and control various aspects within organisms

1. The science that deals with the manipulation of matter at the nanometer-sized scale. In order for a system or process to be considered “nanotech,” it must not only be effective at the nanoscale but must also have unique properties at that scale
4. A large macromolecule that is composed of repeating subunits
6. A process, often during experimentation, performed or taking place in a living organism
10. The extent to which a medication can be used by the body. How a drug interacts with the body
11. Refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers; a nanometer is a billionth of a meter
13. A tube-like structure that may be large enough to serve as a pipe through which other nanoparticles can be channeled
16. The presence of an undesirable element that spoils, corrupts, infects, makes unfit, or makes inferior a material, physical body, natural environment, workplace, etc
18. Carbon-based material or molecule
