摘要:
A system and method for measuring at least one bioprocess parameter utilizes a barrier that separates an external sensor from a culture medium. The barrier allows analytes to diffuse in and out of the culture vessel, thereby allowing the bioprocess parameter to be measured non-invasively by the external sensor.

摘要:
In the present invention, it is demonstrated for the first time, the influence of electrical current on the ability of surface plasmons to amplify fluorescence signatures. An applied direct current across silver island films (SiFs) of low electrical resistance perturbs the fluorescence enhancement of close-proximity fluorophores. For a given applied current, surface plasmons in “just-continuous” low resistance films are sparsely available for fluorophore dipole coupling and hence the enhanced fluorescence is gated as a function of the applied current.

A method and apparatus for a clinical simulation system targets psychological phenomena that can negatively impact the decision making of both a clinician and a patient. Techniques include identifying an independently reasoning agent in a medical clinical information processing system configured to simulate interactions between a clinician and a patient. The method also includes determining, on the system, psychological profile data that indicates one or more personality traits for the agent. The method further includes storing psychological profile data on the system in a hierarchical data structure for a natural language processing system. The method still further includes determining simulation output from the system based at least in part on the psychological profile data.

The present invention provides for increasing fluorescence detection in surface assay systems while increasing kinetics of a bioreaction therein by providing low-power microwaves to irradiate metallic materials within the system in an amount sufficient to increase heat thereby affecting the kinetics of a bioreaction therein.
摘要:
An apparatus and method are disclosed for electrically directly detecting biomolecular binding in a semiconductor. The semiconductor can be based on electrical percolation of nanomaterial formed in the gate region. In one embodiment of an apparatus, a semiconductor includes first and second electrodes with a gate region there between. The gate region includes a multilayered matrix of electrically conductive material with capture molecules for binding target molecules, such as antibody, receptors, DNA, RNA, peptides and aptamer. The molecular interactions between the capture molecules and the target molecules disrupts the matrix's continuity resulting in a change in electrical resistance, capacitance or impedance. The increase in resistance, capacitance or impedance can be directly measured electronically, without the need for optical sensors or labels. The multi-layered matrix can be formed from a plurality of single-walled nanotubes, graphene, or buckeyballs or any kind of conductive nanowire, such as metal nanowires or nanowires made from conductive polymers.

Also disclosed is a contact lens doped with the quaternary nitrogen heterocyclic boronic acid-containing compound, and a method of using the doped contact lens to measure the concentration of analyte in tears under physiological conditions.
摘要:
The present invention relates to methods for functionally modifying a polymeric surface for subsequent deposition of metallic particles and/or films, wherein the polymeric surface is modified by increasing hydroxyl and/or amine functional groups thereby providing an activated polymeric surface for deposition of metallic particles to form a fluorescence sensing device. The device can be used for metal-enhanced fluorescence of fluorophores positioned above the metallic particles that can be readily applied to diagnostic or sensing applications of metal-enhanced fluorescence.

In one aspect, a signal processing system includes a processor, an I/O device operatively associated with the processor, and a memory device bearing instructions configured to cause the processor to obtain a representation of signal data over a data domain and position a sliding-window over a portion of the signal data, such portion corresponding to a sliding-window domain, to analyze the signal data within the sliding-window domain to detect the presence of a signature multiplet and, based on the analysis of the data, to estimate the pedestal of the signal data within the sliding-window domain. The instructions also cause the processor to iteratively shift the sliding-window over at least a portion of the data domain to correspondingly shift the sliding-window domain, estimate the pedestal of the signal data within each sliding-window domain to determine an estimated pedestal over the portion of the data domain, to subtract the estimated pedestal from the signal data to yield a pedestal-free representation of the signal data for the portion of the data domain, and to output the pedestal-free representation of the signal data for the portion of the data domain to a communication device, display, printing device, or data storage device.
摘要:
A process for treatment of sludge made up of saline organic solids or organic waste produced in a saltwater or brackish aquaculture system is described. The process includes use of a modified reactor, operating under anaerobic conditions, which yields methane from the digestion of the saline organic solids. Modification of a traditional reactor to include a packing substrate provides for saline waste digestion not previously known. Additionally provided is a process for producing methane from the digestion of organic solids. Inclusion of and use of modified reactors in aquaculture systems is also provided.
