摘要:
Methods for building sensor arrays using electrical signals to selectively functionalize individual electrodes in an array of electrically addressable electrodes are provided. These methods are useful for providing sensor arrays for use in chemical and biochemical assays. The method is based on the sequential electrochemical reduction of functional groups on individual electrodes in order to selectively promote the functionalization of selected electrodes with selected binding entities.

摘要:
A multipurpose bed sheet system is provided comprising a central bed sheet portion having a substantially rectangular shape with one or more bed sheet flaps extending from one or more edges thereof, where each bed sheet flap may comprise a substantially rectangular, substantially triangular or substantially isosceles-trapezoidal shape. One or more coupling elements may be disposed on each of the one or more bed sheet flaps or disposed on the central bed sheet portion, where each of the one or more coupling elements may be manually removable and manually reattachable with another of the one or more coupling elements. When at least one of the one or more coupling elements are each respectively manually attached with another of the one or more coupling elements, at least one of the one or more bed sheet flaps is secured to a side and a bottom of a mattress and a first end of the central bed sheet portion is secured to a top of the mattress.
摘要:
The invention provides a homogeneous composition comprising a hemostatically effective amount of a charged oxide, wherein the composition has an isoelectric point, as measured in calcium chloride, below 7.3 or above 7.4. Typically, the charged oxide is selected from the group consisting of silaceous oxides, titanium oxides, aluminum oxides, calcium oxides, zinc oxides, nickel oxides and iron oxides. In some embodiments, the composition further comprises a second oxide selected from the group consisting of calcium oxide, sodium oxide, magnesium oxide, zinc oxide, phosphorus oxide and alumina. In a typical embodiment of the invention, the charged oxide is silaceous oxide, the second oxide comprises calcium oxide and the ratio, by molar ratio, of silaceous oxide to calcium oxide is 0.25 to 15. Optionally, the composition further comprises phosphorous oxide. Also described are methods of making and using such compositions.
