Xenon Xe 129 hyperpolarized, sold under the brand name Xenoview, is a hyperpolarized contrast agent indicated for use with magnetic resonance imaging (MRI) for evaluation of lung ventilation, and approved for people aged twelve years of age and older. [4] [5] It was approved for medical use in the US in December 2022. [6]
Biosensors International also licenses its proprietary drug-eluting stent technologies to other medical device companies and specialty stent providers, including Terumo, Devax, Inc., and Xtent, Inc. Biosensors International Group has a joint-venture in Hong Kong listed as Shandong Weigao to market and distribute coronary stents in China. [1]
Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...
Spin exchange optical pumping (SEOP) [3] is one of several hyperpolarization techniques discussed on this page. This technique specializes in creating hyperpolarized (HP) noble gases, such as 3 He, 129 Xe, and quadrupolar 131 Xe, 83 Kr, and 21 Ne. [4] Noble gases are required because SEOP is performed in the gas phase, they are chemically inert, non-reactive, chemically stable with respect to ...
Xenon isotope geochemistry uses the abundance of xenon (Xe) isotopes and total xenon to investigate how Xe has been generated, transported, fractionated, and distributed in planetary systems. Xe has nine stable or very long-lived isotopes. Radiogenic 129 Xe and fissiogenic 131,132,134,136 Xe isotopes are of special interest in geochemical ...
Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
Electrochemical aptamer-based (E-AB) biosensors is a device that takes advantage of the electrochemical and biological properties of aptamers to take real time, in vivo measurements. An electrochemical aptamer-based (E-AB) biosensor generates an electrochemical signal in response to specific target binding in vivo [ 3 ] The signal is measured ...
The xenonium ion, XeH +, is an onium compound, consisting of protonated xenon. Although the existence of the xenonium salts has not been proven, the isolated XeH + ion is known. [ 2 ] Salts of the fluoroxenonium ion, XeF + , are known to exist, for instance fluoroxenonium pentafluoroplatinate (XeFPtF 5 ), more commonly known as xenon ...
