20110060188 | LOW COST DISPOSABLE MEDICAL FORCEPS TO ENABLE A HOLLOW CENTRAL CHANNEL FOR VARIOUS FUNCTIONALITIES - The present invention relates to an endoscopic biopsy forceps ( | 03-10-2011 |
20110313145 | ISOLATION OF RNA - Disclosed herein are methods for purification of RNA from a sample. The RNA can be total RNA or mRNA. The method involves preparing the sample in a solution of lysis buffer and depositing into a first end of a lysis straw such that the sample solution flows through the matrix of the lysis straw and is eluted from the opposite end of the lysis straw, and depositing the eluted material into a first end of a solid phase extraction (SPE) straw, such that the deposited solution flows through the matrix of the SPE straw towards the opposite end of the SPE straw, and eluting the RNA from the SPE straw by depositing a solution of elution buffer, into the first end of the SPE straw, such that the deposited solution flows through the matrix of the SPE straw and is eluted from the opposite end of the SPE straw, wherein purified RNA from the sample is present in the eluate of the SPE straw. When the RNA is total RNA, and the sample is a cell sample, and step b) requires adding a precipitating solution to the eluted material from step a), and depositing the solution into the first end of the SPE straw, wherein the straw comprises silica microspheres, such that the deposited solution flows through the matrix of the SPE straw toward the opposite end of the SPE straw. When the RNA is mRNA and step b) further comprises depositing the solution into the first end of the solid phase extraction (SPE) straw, wherein the straw comprises oligo-dT. Pressure (e.g., at least 10 psi pressure) and heat (e.g., about 60° C.) can be applied to the samples, and/or eluates and/or straws. Examples of lysis buffers, loading buffers and elution buffers are provided. Also disclosed are the specific straws and porous polymer monolith matrix components. | 12-22-2011 |
20120077260 | RESERVOIR-BUFFERED MIXERS AND REMOTE VALVE SWITCHING FOR MICROFLUIDIC DEVICES - The present invention relates generally to the control of fluid flow rate and direction on a microfluidic device. In particular, the present invention provides an integrated valveless microfluidic device, where directional fluid control is controlled using off-chip remote valve switching and fluid flow rate changes are controlled using on-chip flow-rate changing fluid reservoirs. The present invention provides methods and systems for directional fluid control and control of fluid flow rate in an integrated microfluidic device which enables processes with different flow rates to be performed on one device without the need of on-chip valves. | 03-29-2012 |
20120115705 | DISPOSABLE SEPARATOR/CONCENTRATOR DEVICE AND METHOD OF USE - The present invention relates to methods, devices and systems for separation and concentration of particles from liquid and fluid samples. In some embodiments, the separation/concentration is achieved by sequential centrifugation steps. In particular, one aspect of the invention relates to a separation/concentration device which comprises at least a first chamber ( | 05-10-2012 |
20120122831 | METHOD AND DEVICE FOR RAPID DETECTION OF BACTERIAL ANTIBIOTIC RESISTANCE/SUSCEPTIBILITY - Described herein is a method and a device for expediting delivery of an agent to a damaged bacterial cell. In one embodiment, the methods and devices are useful for screening candidate antibiotics. In another embodiment, the methods and devices described herein are used to determine susceptibility of bacteria to an antibiotic. The methods also provide a method for determining an appropriate antibiotic to treat an individual having a bacterial infection. | 05-17-2012 |
20120267949 | SYSTEM FOR WAVE ENERGY HARVESTING EMPLOYING TRANSPORT OF STORED ENERGY - A system employs wave energy harvesting apparatus and a water vessel (e.g., a ship) carrying an energy storage apparatus (e.g., array of batteries). The energy harvesting apparatus is preferably also carried by the water vessel, but may be fixed or carried by a separate water vessel. The water vessel is operated in an energy storing mode at an energy harvesting location subject to wave activity, during which the energy storage apparatus stores energy from the wave activity as harvested by the energy harvesting apparatus. The water vessel is operated in an energy transporting mode to transport the stored energy from the energy harvesting location to an energy releasing location (preferably onshore, but may be offshore) having a connection to an electrical power grid. The water vessel is operated at the energy releasing location in an energy releasing mode in which the stored energy is transformed into appropriate AC electricity supplied to the electrical power grid. | 10-25-2012 |
