摘要： The present invention provides an optical fluorescence based sensor for measuring the concentration of a gas (e.g., CO2 or ammonia) in a medium such as blood which has superior dry web sensor performance, enhanced sensor consistency for transparent sensor calibration, improved autoclave stability and rapid rehydration of the sensor. In a preferred embodiment, the sensors of the present invention comprise microcompartments of an aqueous phase having a pH sensitive indicator component and a nonionic amphipathic surfactant within a hydrophobic barrier phase comprising a plurality of dispersed hydrophobic particles.

摘要： A method forms self-sustaining particles that comprise a hydrophobic (oleophilic) phase in particulate form, with no need for a rigid shell to encapsulate the phase, and usually with no shell present. The oleophilic phase contains a gelation agent, and preferably an organogelation agent. The particles may be stored alone or in a minor amount (e.g., less than 40% by volume) of water to assist their stability and act as a barrier against their coalescence. These water-separated compositions are not necessarily dispersions or suspensions, but may be merely particles in an aqueous storage environment. The particles have prolonged stability and can be readily, simply, and inexpensively formed. A simple method of manufacture comprises forming a solution of the ingredients (e.g., at least the oleophilic material and gelation agent) at a temperature above their gelation temperature, forming droplets or molten, or liquid or flowable particles of the solutions, and cooling the droplets to form the particulates. Cooling may be effected by exposure to ambient conditions (e.g., room temperature) when the ingredients are properly selected, or an actual cooling environment may be needed.
摘要翻译：一种方法形成包含颗粒形式的疏水（亲油）相的自持颗粒，不需要刚性壳来包封相，通常没有壳存在。亲油相含有凝胶剂，优选有机凝胶剂。颗粒可以单独存储或以少量（例如，少于40体积％）的水储存，以有助于其稳定性并作为阻止其聚结的屏障。这些水分离的组合物不一定是分散体或悬浮液，而是可以仅仅是水性储存环境中的颗粒。颗粒具有延长的稳定性，并且可以容易地，简单地且廉价地形成。一种简单的制造方法包括在高于其凝胶化温度的温度下形成成分溶液（例如，至少亲油性材料和凝胶化剂），形成液滴或熔融或液体或可流动的溶液颗粒，并冷却液滴形成颗粒物。当适当选择成分或可能需要实际的冷却环境时，可以通过暴露于环境条件（例如室温）来实现冷却。

摘要： Various materials, including generally non-compatible materials may be provided from a single delivery system by a unique encapsulation system. An encapsulation system is advantageously constructed as a core of aqueous liquid having at least 5% by weight water therein, and an encapsulant surrounding the core to form a stable encapsulated particle, the encapsulant comprising at least one layer of hydrophobic particles in contact with and surrounding the core, the core and hydrophobic particles providing an encapsulated system that has an average weight average particle diameter of from 0.05 to 25 micrometers and can support its own weight. The encapsulation system may be provided by a novel method of manufacture comprising providing a mass of hydrophobic particles having average mass diameter size of between 0.05 and 25 micrometers, providing droplets of an aqueous medium to the mass of particles, gently mixing the fine particles of aqueous medium and the hydrophobic particles to form a stable encapsulant system of droplets of the aqueous medium encapsulated by a shell of particles.
