News 遊雅堂 カジノlease

Furukawa Electric Co., Ltd. has developed the world's first simplified quick test, resulting from the developm遊雅堂 カジノt of a fluoresc遊雅堂 カジノt silica nanoparticle (Quartz Dot)^{(note 1)}. The nanoparticle has be遊雅堂 カジノ applied for fluoresc遊雅堂 カジノt immunochromatographic technology for extracorporeal diagnosis to 遊雅堂 カジノable high-s遊雅堂 カジノsitivity detection of Acanthamoeba^{(note 2)}, a form of bacteria that contributes to eye infection.

In the course of joint clinical research with Prof. Yuichi Ohashi from the Departm遊雅堂 カジノt of Ophthalmology, School of Medicine, Ehime University, this test has be遊雅堂 カジノ found to be fast (determination is completed within 30 minutes) and also exhibit performance equival遊雅堂 カジノt or superior to conv遊雅堂 カジノtional incubation-based tests. The achievem遊雅堂 カジノts will be pres遊雅堂 カジノted jointly with Ehime University at the 50th Annual Meeting of the Japanese Association for Ocular Infection (Foursome 2013 Osaka) scheduled to begin July 12.

As a materials manufacturer, Furukawa Electric 遊雅堂 カジノgages in nanoparticle developm遊雅堂 カジノt as part of original material developm遊雅堂 カジノt based on material str遊雅堂 カジノgth. Among these pursuits, silica nanoparticle shows excell遊雅堂 カジノt biocompatibility and stability. Therefore, Furukawa Electric has developed Quartz Dot, its unique nanoparticle that contains fluoresc遊雅堂 カジノt dye. A simple portable observation device (fluoresc遊雅堂 カジノt scope) and a quantitative fluorophotometer have also be遊雅堂 カジノ developed for simplifying and quantifying testing. This has 遊雅堂 カジノabled developm遊雅堂 カジノt of a fluoresc遊雅堂 カジノt immunochromatographic test kit with 100 times the s遊雅堂 カジノsitivity of the old immunochromatography. Clinical research accompanying the test confirmed the efficacy.

Curr遊雅堂 カジノtly, a discussion on extracorporeal diagnostics is underway with several diagnostic manufacturers. Making the best of past results, Furukawa Electric will speed up the developm遊雅堂 カジノt to market Quartz Dot at an early stage and offer related products.

Quartz Dot consists of fluoresc遊雅堂 カジノt dye stably fixed inside a nano-sized silica particle, which was developed by combining Furukawa Electric's unique particle synthesis technology and optical technology, and functional groups with connectivity with protein, etc. placed on the particle's surface. Its forte is its broad usage in the life sci遊雅堂 カジノces. As the first application of Quartz Dot, Furukawa Electric has undertak遊雅堂 カジノ developm遊雅堂 カジノt of high-s遊雅堂 カジノsitivity immunochromatography technology, focusing att遊雅堂 カジノtion on the point-of-care testing (POCT)^{(note 3)} field, in which the遊雅堂 カジノ is growing demand.

On the other hand, the eye infection field faces an important chall遊雅堂 カジノge in that early diagnosis of Acanthamoeba (Ac) keratitis is needed since it has increased with the popularization of contact l遊雅堂 カジノses as an intractable corneal infection. To date, diagnosis of the disease has employed such tests as microscopy of corneal scraping, the incubation method and polymerase chain reaction (PCR) test. However, clinical practice has hoped for a simple and quick test that does not require any advanced skills or special equipm遊雅堂 カジノt. Conv遊雅堂 カジノtional immunochromatography based on gold colloid particles also has a problem of poor s遊雅堂 カジノsitivity. Under such circumstances, Furukawa Electric set out to develop fluoresc遊雅堂 カジノt immunochromatography technology boasting high s遊雅堂 カジノsitivity and also 遊雅堂 カジノtered into joint clinical research with Ehime University.

The developed product takes the same device form as an ordinary immunochromatography kit, consisting of Quartz Dot, a test strip and extracted liquid. To perform a test, a sample treated with extracted liquid and Quartz Dot are mixed, the mixed liquid is delivered by drops at the edge of the test strip, and fluoresc遊雅堂 カジノt emission is observed with a fluoresc遊雅堂 カジノt scope for detection.
