Abstract: A corrosion sensor having a corrodible element that is corrodible in a lubricant or hydraulic oil, wherein the corrosion sensor is adapted to monitor degradation of the lubricant or hydraulic oil is disclosed.

Abstract: A nanoparticle having a self assembly monolayer of molecules as a shell on the nanoparticle. The monolayer may include organic molecules working as surface enhanced Raman spectroscopy (SERS) reporters. Also, the core shell may include at least a receptor, and/or the like, to ensure that a target analyte can be bound for measurement with SERS. The target analyte may be organic, chemical, biological, inorganic, gas, liquid, solid, and so forth.

Abstract: The present invention relates to an apparatus for testing multiple sample compounds for their biological effect comprising a porous block having substantially planar top and bottom surfaces. The top surface comprises a plurality of cell adhesive regions and cell dis-adhesive regions and the bottom surface provides multiple sites to load the sample compounds. These sites are located opposite from the cell adhesive regions on the top surface of the porous block. In certain embodiments, the invention further comprises at least one dissolvable layer which provides multiple sites to load the sample compounds.

Abstract: A method of creating a metal nanoparticle hydrogel biological array comprises placing a plurality of metal nanoparticles in each of a plurality of wells on a substrate, and placing a biomolecular probe material into the plurality of wells. Hydrogel precursors are placed in each of the plurality of wells; and are polymerized to form hydrogel such that the metal nanoparticles are embedded in the hydrogel.
