Abstract: Described herein are composite semiconductor substrates for use in semiconductor device fabrication and related devices and methods. In one embodiment, a composite substrate includes: (1) a bulk silicon layer; (2) a porous silicon layer adjacent to the bulk silicon layer, wherein the porous silicon layer has a Young's modulus value that is no greater than 110.5 GPa; (3) an epitaxial template layer, wherein the epitaxial template layer has a root-mean-square surface roughness value in the range of 0.2 nm to 1 nm; and (4) a set of silicon nitride layers disposed between the porous silicon layer and the epitaxial template layer.

Abstract: A hydrolyzed dye/gel polymer for use in a pH-based sensor is characterized by its chemical and optical stability with respect to dye loss with time. Preferably, the dye/gel polymer is hydrolyzed by heating in a dilute base solution for a period of time sufficient to remove weakly bonded dye molecules from the polymer, then washed to remove the base solution and loose dye.

Abstract: A multiple sensor which can be readily inserted into, and removed from a radial arterial cannula for use in continuous in vivo patent monitoring includes a plurality of individual sensors, each sensor including a sensing element disposed on an optical waveguide, the sensors being bonded together by an adhesive without covering the sensing elements.

Abstract: An electrode for use in miniaturized sensor applications includes an electrically conductive element, a first layer of a salt on the surface of the conductive element having a common cation with the conductive element, a second layer of a second salt coating the first layer, the second layer having a common anion with the first layer, and a membrane covering the second layer, wherein the electrode is completely anhydrous when formed. The membrane may be selected to form either an ion selective electrode or a reference electrode.
