    摘要: This invention provides novel high density memory devices that are electrically addressable permitting effective reading and writing, that provide a high memory density (e.g., 1015 bits/cm3), that provide a high degree of fault tolerance, and that are amenable to efficient chemical synthesis and chip fabrication. The devices are intrinsically latchable, defect tolerant, and support destructive or non-destructive read cycles. In a preferred embodiment, the device comprises a fixed electrode electrically coupled to a storage medium having a multiplicity of different and distinguishable oxidation states wherein data is stored in said oxidation states by the addition or withdrawal of one or more electrons from said storage medium via the electrically coupled electrode.

    摘要: Sinusoidal voltammetry was employed to detect both purine and pyrimidine-based nucleic acids. Adenine and cytosine, representing these two classes of nucleic acids, could be detected with nanomolar detection limits at a copper electrode under these conditions, where the sensitivity for adenine was much higher than that for cytosine. Detection limits for purine-containing nucleotides (e.g., adenosine 5'-monophosphate (AMP), adenosine 5'-diphosphate (ADP), and adenosine 5'-triphosphate (ATP)) were on the order of 70-200 nM using this method. These detection limits are achieved for native nucleotides and are over two orders of magnitude lower than those found with UV absorbance detection. Pyrimidine-based nucleotides could also be detected with high sensitivity due to the presence of a sugar backbone which is electroactive at the copper surface. This detector is not fouled by the nucleotides and can be used for the sensitive detection of analyses eluting continuously from a chromatography column or a electrophoresis capillary. Entire nucleic acid molecules can be readily detected. For example, both single stranded and double stranded DNA is detected with a detection limit in the picomolar concentration range (i.e., 10.sup.-12 moles/L). In the present invention, the signal from a double stranded DNA is roughly twice that arising from a single stranded DNA strand of the same length.

    摘要: The present invention relates to the use of a distributable sampling and sensing system for the determination of volatile components of consumable foods and other agricultural products. This process is used to separate and concentrate the chemicals of interest from samples at remote locations onto a target substrate that can be analyzed on-site or at a central lab. The chemicals deposited onto the substrate can be analyzed on-site with specific sensors (e.g., electrochemical sensors) or the target substrate can be sent to a central lab where the components adsorbed within are analyzed with conventional chemical instrumental methods (e.g., GC-MS). This process provides sufficient flexibility to enable the chemical analysis of a wide range of chemical species of interest in target materials in remote locations.
