20090053108 | CENTRIFUGAL FORCE-BASED MICROFLUIDIC DEVICE FOR BLOOD CHEMISTRY ANALYSIS - Provided is a microfluidic device that can automatically perform various types of biological blood analysis. In the microfluidic device, a specimen is centrifugally separated and the centrifugally separated specimen is diluted into various dilution ratios. Also, at least two reagents that are required for one reaction and that need to be separately stored are stored in separate chambers, and they are mixed when a reaction is needed. Thus, various conventional blood analyzing reagents can be used as they are or after being minimally processed in the microfluidic device. | 02-26-2009 |
20090317918 | METHOD OF HEATING LIQUID MEDIUM USING MICROWAVES AND ANIONS - Provided is a method comprising adding anions having a high charge density to a liquid medium; the liquid medium comprising molecules that hydrogen bond with one another; the anions interacting with the molecules of the liquid medium with a force that is stronger than the forces that produce hydrogen bonding between the molecules of the medium; and heating the liquid medium by irradiating it with microwaves. | 12-24-2009 |
