Dip-pen nanolithography (dpn)
| Глоссарий терминов в нанотехнологиях |
A method for nanoscale patterning of surfaces by the transfer of a material from the tip of an atomic force microscope onto the surface. developed by professor chad a. mirkin, the dpn allows researchers to precisely lay down or “write” chemicals, metals, biological macromolecules, and other molecular “inks” with nanometer dimensions and precision on a surface.

Patterning, английский
Microscope, английский
- Microscopio
- A scientific instrument with lenses, which makes very small objects appear larger the tissue was examined under the microscope. under the microscope it was possible to see the cancer cells. comment: in an ordinary or light microscope the image is magnified by lenses. in an electron microscope the lenses are electromagnets and a beam of electrons is used instead of light, thereby achieving much greater magnifications.
- Device used to form a highly magnified image of tiny objects for clear visualization
- Instrument that provides enlarged images of small objects. microscope, compound: conventional microscope, using geometrical optics for magnification. also called laboratory microscope. microscope, interference: magnifier using the wavelength of light as a unit of measure for surface contour and other characteristics. microscope, metallographic: metallurgical microscope incorporating a camera. also called a metallograph. most metallographic microscopes share these features: (a) stand with concealed shock absorbers, (b) intense light source, (c) inverted stand so that the test object is face down, (d) viewing screens for prolonged tasks such as dirt count or grain size measurements, (e) bright, dark and polarized illumination options. microscope, metallurgical: microscope designed with features suited for metallography. microscope, phase contrast: laboratory microscope with two additional optical elements to transmit both diffracted and undiffracted light, revealing refractive index discontinuities in a completely transparent test object. microscope, polarizing: microscope with polarizing elements to restrict light vibration to a single plane for studying material with directional optical properties. as fibers, crystals, sheet plastic and materials under strain are rotated between crossed polarizers on the microscope stage, they change color and intensity in a way that is related to their directional properties. mig welding: see gas metal arc welding.
- Instrument that provides enlarged images of very small objects.
Biological, английский
Биологический
Dimensions, английский
- (главные) размерения
- Height, width, length of an article (e.g.: container, cargo) measured parallel to each of its axes ad expressed in order.
- Соответствие проектным геометрическим размерам
- Размеры груза (длина, ширина, высота)

Dna bricks, английский
A lego-like dna block that is used in dna technology to build 2d and 3d nanostructures.
Dendrimer, английский
A polymer with multiple branches. dendrimers are synthetic 3-d macromolecular structures that interact with cells, enabling scientists to probe, diagnose, treat, or manipulate cells on the nanoscale. from the greek word dendra, meaning tree.
