Patent number: 7521246Abstract: Provided is a cell lysis method including: preparing a cell sample to be lysed; heating the cell sample; and cooling the cell sample by causing an endothermic reaction near the cell sample. According to the method, cell lysis can be simply and conveniently performed without regard to location and without additional devices since a separate energy source is not required and the apparatus is portable. In particular, when cell lysis is performed in a biochip using a small amount of sample, a greater cell lysis effect can be obtained. In addition, cell lysis efficiency is significantly improved, compared to when only heating is performed.Type: GrantFiled: January 19, 2006Date of Patent: April 21, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Ji-yeon Yang, Yoon-kyoung Cho, Jin-tae Kim, Sook-young Kim, Young-sun Lee

Publication number: 20090098657Abstract: An assembly determines an analyte concentration in a sample of body fluid. The assembly includes a test sensor having a fluid-receiving area for receiving a sample of body fluid, where the fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the sample. The assembly also includes a meter having a port or opening configured to receive the test sensor; a measurement system configured to determine a measurement of the reaction between the reagent and the analyte; and a temperature-measuring system configured to determine a measurement of the test-sensor temperature when the test sensor is received into the opening. The meter determines a concentration of the analyte in the sample according to the measurement of the reaction and the measurement of the test-sensor temperature.Type: ApplicationFiled: October 15, 2008Publication date: April 16, 2009Inventors: Jeffrey D.

Patent number: 7517692Abstract: The present invention relates to a technique for causing the temperature of a liquid component retained in an analytical tool (1) to be adjusted to a target temperature, wherein the analytical tool (1) is used for analyzing the sample. According to the present invention, the temperature of the liquid component (10) is raised by heating the liquid component utilizing light energy from a light source (23). The temperature raising of the liquid component may be performed by supplying the light energy directly to the liquid component. Alternatively, the temperature raising of the liquid component may be performed by thermal energy transferred from a temperature raise region adjacent to the liquid component to which the light energy supplied. Preferably, as the light source (23) for raising temperature, use may be made of a laser diode or a light-emitting diode.Type: GrantFiled: April 28, 2003Date of Patent: April 14, 2009Assignee: Arkray, Inc.Inventors: Takayuki Taguchi, Shigeru Kitamura

Patent number: 7497993Abstract: The present invention is a fluorescent temperature sensor or optical thermometer. The sensor includes a solution of 1,3-bis(1-pyrenyl)propane within a 1-butyl-1-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid solvent. The 1,3-bis(1-pyrenyl)propane remains unassociated when in the ground state while in solution. When subjected to UV light, an excited state is produced that exists in equilibrium with an excimer. The position of the equilibrium between the two excited states is temperature dependent.Type: GrantFiled: September 7, 2004Date of Patent: March 3, 2009Assignee: The United States of America as represented by the United States Department of EnergyInventors: Gary A.
