    • The present invention provides a membrane the conductivity of which is dependent on the presence or absence of an analyte. The membrane comprises a closely packed array of self-assembling amphiphilic molecules and two ionophore components. A receptor molecule reactive with the analyte is provided on one of the ionophore components. The binding of the analyte to the receptor molecule causes a change in the relationship between the ionophore components such that the flow of ion across the membrane is prevented or allowed. The ionophore components are preferably selected from the group consisting of amphotericin B, gramicidin A monomers and combinations thereof, with gramicidin A monomers being particularly preferred. The present invention also provides a membrane including receptors directed against the Fc region of antibodies. These receptors are preferably derived from polyclonal antibodies. These membranes provide a ''generic'' surface which will bind antibodies in a manner such that the antigen binding regions of the antibody are not hindered. The present invention further provides a device adapted for implantation in a mammalian body, the device being characterised in that it is coated with a membrane comprising a closely packed array of self-assembling amphiphilic molecules and receptor molecules, the receptor molecules being such that the attachment of specific cells to the membrane is enhanced or avoided. It is particularly preferred that the receptor molecules are directed against fibronectin, vitronectin, endothelial cells, or epithelial cells. It is further preferred that the membrane coating the device also includes a plurality of ion channels such as gramicidin.
    • 本发明提供了其导电性取决于分析物的存在或不存在的膜。 膜包括紧密堆积的自组装两亲分子和两个离子载体组分的阵列。 在离子载体组分之一上提供与分析物反应的受体分子。 分析物与受体分子的结合导致离子载体组分之间的关​​系发生变化,从而防止或允许穿过膜的离子流。 离子载体组分优选选自两性霉素B,短杆菌肽A单体及其组合,特别优选短节杆菌肽A单体。 本发明还提供了包含针对抗体Fc区的受体的膜。 这些受体优选衍生自多克隆抗体。 这些膜提供了“通用”表面,其将以使得抗体的抗原结合区不受阻碍的方式结合抗体。 本发明还提供一种适于植入哺乳动物体内的装置,该装置的特征在于其涂覆有包含紧密堆积的自组装两亲分子阵列和受体分子的膜,受体分子使得附着物 的特定细胞被增强或避免。 特别优选的是受体分子针对纤连蛋白,玻连蛋白,内皮细胞或上皮细胞。 进一步优选的是,涂覆该装置的膜还包括多个离子通道,例如短杆菌肽。

    • The invention provides an in vivo screening assay and an in vitro screening assay for rapid screening of diabetes. A method of the invention includes determining a first glucose concentration in an ocular fluid of a patient; administering orally a load of carbohydrate to the patient; determining a second glucose concentration in an ocular fluid of the patient at a period of time of less than 50 minutes after orally administering of the load of carbohydrate; comparing the second glucose concentration with the first glucose concentration to determine if the patient is likely to be a diabetic. The method of the invention is performed by using a kit of the invention. The kit comprises: (1) a glucose-sensing ophthalmic device and instructions for using the glucose-sensing ophthalmic device to screen for diabetes; or (2) two or more tear-collecting devices, and a testing agent composition which specifically reacts with glucose to form a detectable signal. The glucose-sensing ophthalmic device comprises a testing agent composition which specifically and reversibly interacts with glucose to form a detectable optical signal which changes in a concentration-dependent manner.
    • 本发明提供体内筛选测定和用于快速筛选糖尿病的体外筛选测定。 本发明的方法包括确定患者眼部流体中的第一葡萄糖浓度; 向患者口服负荷的碳水化合物; 在口服施用碳水化合物之后,在小于50分钟的时间内测定患者眼液中的第二葡萄糖浓度; 将第二葡萄糖浓度与第一葡萄糖浓度进行比较以确定患者是否可能是糖尿病。 本发明的方法通过使用本发明的试剂盒进行。 试剂盒包括:(1)葡萄糖感测眼科装置和使用葡萄糖感测眼科装置筛查糖尿病的说明书; 或(2)两种或更多种泪液收集装置,以及与葡萄糖特异性反应以形成可检测信号的检测剂组合物。 葡萄糖感测眼科装置包括与葡萄糖特异性和可逆地相互作用以形成以浓度依赖性方式变化的可检测光学信号的测试剂组合物。
