Patent number: 7807360Abstract: A method of sequentially performing concentration and amplification of nucleic acid in a single micro chamber includes: introducing a nucleic acid-containing sample and a solution including a kosmotropic salt to a micro chamber having a hydrophilic interior surface to concentrate the nucleic acid by binding the nucleic acid on the interior surface of the micro chamber; and performing a polymerase chain reaction (PCR) by adding a PCR mixture to the chamber. Since the nucleic acid is reversibly bound to the interior surface of the micro chamber, PCR yield is higher compared with a surface of aluminum oxide in which irreversible binding occurs. In addition, all processes are sequentially performed in a single micro chamber so that the number of samples, consumables, time, and labor for treatment and analysis can be reduced, detection sensitivity can be improved, and risk of sample cross contamination significantly reduced without sample loss by eliminating transporting of the sample.Type: GrantFiled: January 8, 2007Date of Patent: October 5, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Young-rok Kim, Jun-hong Min, In-ho Lee, Young-sun Lee, Chang-eun Yoo, Ki-woong Han

Publication number: 20060230347Abstract: The present invention is related to easily and rapidly inputting a character into a mobile terminal. Preferably, a first character is inputted into the mobile terminal using a first key associated with at least one allocated alphabetical character. A second character is then inputted by pressing a second key not associated with an allocated alphabetical character, wherein the second key is reserved for inputting the second character according to an alphabetical position of the second character relative to the first character. Accordingly, a user may input a preceding or succeeding character or a previously-inputted character in alphabetical order, re-input the previously-inputted character, or input another character allocated to a key without having to manually move a display cursor or wait for the display cursor to move automatically.Type: ApplicationFiled: April 5, 2006Publication date: October 12, 2006Inventor: Ki-Woong Han
