摘要:
The present invention provides a microfluidic device for preparing or extracting a biological sample from a solid material and methods for using the same. The microfluidic device of the invention automates the biological sample extraction from a solid material, thereby significantly reducing the possibility of contamination, human error and a potential variability of the sample that is obtained by different technicians.

Methods, apparatuses, and systems for collecting samples using hybrid porous materials that include an organic material and an inorganic material. A method for sample collection includes contacting a hybrid porous material and a biological sample to the porous material. The hybrid porous material includes an inorganic material and an organic material. The method includes placing the porous material with the attached sample in a liquid medium, wherein the sample is separated from the porous material in the liquid medium to form a separated sample, and collecting the separated sample in the medium.

A method of verifying the performance of a size standard, formed of a plurality of size standard elements, used in a nucleic acid analysis method is provided. The verification is achieved by introducing the size standard to an analysis stage and performing a size based separation on the size standard. The size based separation defines an experimental position for each size standard element. A comparison is made as to whether or not the experimental position for the size standard element corresponds with expected position. The comparison allows a decision to be made on whether or not to use the size standard, which is dependent upon whether or not the experimental position of the size standard element corresponds with the expected position.
摘要:
Apparatus and methods for monitoring, analyzing, and/or discriminating molecular species, preferably a biomolecule, within a medium using a multisensor array (MSA) and multivariate processing. Biological compounds such as nucleotides and polynucleotides can be detected and analyzed. A reaction process such as an accumulation cycle of nucleic acids can be monitored, analyzed, and controlled using a multisensor array (MSA) and multivariate processing. Monitoring a biomolecule includes interrogating the medium, and preferably its gas phase, by coupling a sensor responsive to any changes of the medium and or biomolecule and its secondary products when, for example, an amplification reaction is proceeded. It is also a scope of the present invention to use direct detection and monitoring of biomolecular reactions in real-time without radioactive or fluorescent labeling. A preferred application is real-time polymerase chain reaction (PCR) detection.

An exemplary system and method of employing DNA hybridization for the detection of bio-agents is disclosed as comprising inter alia a biomolecular rotary motor (150); a capture probe DNA fragment (140) effectively attached to said biomolecular motor (150); a target DNA fragment (130) suitably adapted for hybridization with said capture probe DNA (140); a signal probe DNA fragment (120) suitably adapted for hybridization with said target DNA (130); and a fluorescent bead (100) attached to said signal probe DNA (120). Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve certain device fabrication parameters and/or performance metrics.
摘要:
A method for deriving physical properties of a workpiece. The method comprises the steps of sampling an electromagnetic wave packet representative of workpiece properties and comprising encoded scattered wave information derivable from a multi-pole interactive coupling between a probe tip and the workpiece; decoding said electromagnetic wave packet by interrogating at least one of its phase and amplitude information; and, correlating this information to referent physical-chemical properties of the workpiece.

A matching of a traveler's gear and vehicle when engaging into an electronic transaction of on demand services, preferably for transportation. In a preferred embodiment, the present method and apparatus is suitable for assessing remotely from a digital image, the physical properties of a travel gear, for example its shape, size and weight dimensions or texture, in order to match the geometric parameters of the container storage of a vehicle, for example the trunk of an automobile, listed in a database of an electronic transportation service, in order to optimize the conditions of transportation, such as cost reduction and energy fuel efficiency, for improving the quality of the traveler's experience.
摘要:
Collection devices and kits for biological sample collection include a biologic sample collection device having a hydrophilic swab matrix that includes a modified polycaprolactone (PCL). Methods of production and use thereof are also described herein. The biologic sample collection devices, kits and methods described herein are used to collect a biologic sample (e.g., blood, buccal cells, etc.) and to enable extraction of nucleic acids (e.g., DNA) from that biologic sample so that the nucleic acids can be analyzed (e.g., sequencing and subsequent analysis of DNA).
摘要:
A method and system to predict a design of an article of manufacture, which can include the steps of introducing a biological organism into a test environment to activate at least one molecular component of the biological organism representing at least one set of genetic characters of the biological organism; monitoring for change in at least one expression phenomenon pattern in response to the test environment; translating the monitored change in the at least one expression phenomenon pattern into a molecular data profile; interrogating the molecular data profile against a stored database to generate an information pattern of a phenotype correlated to the molecular data profile; and translating the information pattern of the phenotype into a correlated design component of the article of manufacture.
