摘要:
A memory device, including a plurality of nanoscale memory cells (1510, 1512) created by applying pressure to and removing pressure from one or more regions (1510, 1512) of a substance (1502) to change the electrical conductivity of those regions (1510, 1512). An electrically conductive read probe (1514) determines the conductivities of the regions and thereby the information stored in the cells. A write probe (1508) applies pressure to and removes pressure from selected cells to change the electrical conductivity of those cells and thereby store or erase information.
摘要:
The device for recording data comprises a network of carbon nanotubes (9) formed on a planar substrate (10) and forming microdots which cooperate with a storage medium (11) which is substantially planar. The carbon nanotubes (9) are initially inclined at a predetermined angle ranging from 5° to 40°, in relation to the plane of the substrate (10). The naontubes 9 bend when they come into contact with the storage medium (11), parallel to the substrate (10). Preferably, the substrate (10) comprises a relief structure which is used to provide support for the free extremities of the nanotubes (9).

In accordance with the present invention, there is provided an apparatus comprising a tape having an information layer on which information is storable in the form of perturbations, an array (10) of probes (11) that in function faces the tape (2) such that the probes scan the surface of the tape, means for selectively forming the perturbations via the probes, means for detecting the presence of the perturbations via the probes, and drive means (20, 25, 40, 42) for moving the tape relative to the array of probes. The apparatus allows to store high data capacities at a small form factor.
摘要:
The present invention concerns a cantilever arrangement for scanning a surface (16). This arrangement comprises a first cantilever (11) having a first probe (14) and a second cantilever (13) having a second probe (15). Both cantilevers (11, 13) are mechanically coupled such that the second cantilever (13) follows the movement of the first cantilever (11), i.e. the deflection of the first cantilever (11) defines the deflection of the second cantilever (13).
摘要:
Encoded combinatorial chemistry is provided, where sequential synthetic schemes are recorded using organic molecules, which define choice of reactant, and stage, as the same or different bit of information. Various products can be produced in the multi-stage synthesis, such as oligomers and synthetic non-repetitive organic molecules. Conveniently, nested families of compounds can be employed as identifiers, where number and/or position of a substituent define the choice. Alternatively, detectable functionalities may be employed, such as radioisotopes, fluorescers, halogens, and the like, where presence and ratios of two different groups can be used to define stage or choice. Particularly, pluralities of identifiers may be used to provide a binary or higher code, so as to define a plurality of choices with only a few detachable tags. The particles may be screened for a characteristic of interest, particularly binding affinity, where the products may be detached from the particle or retained on the particle. The reaction history of the particles which are positive for the characteristic can be determined by the release of the tags and analysis to define the reaction history of the particle.
