Abstract: In various embodiments, the disclosed wireless sensors comprise chemically-sensitive conductor traces that respond to variations in the polymer surrounding the sensors due to the change in proximity of the chemicals stored within the polymer vessels (e.g., degradation of the structural integrity of the polymer vessel). The sensors may generally be installed at the interface between the corrosion barrier and the structural layers of a polymer vessel comprising any FRP, PTFE, plastic, or other polymers. As the chemical stored within the polymer vessel degrades or permeates the corrosion barrier, the impedance measured by the sensor, in one embodiment, changes, which signals a change in the structural integrity of the polymer in which the sensor is embedded.

Abstract: This document relates to two dimensional (2D) protein arrays can be used in biotechnology applications, as well as methods of making and using 2D protein arrays. In some cases, a 2D protein array can be used to evaluate (e.g., image) a structure (e.g., a three dimensional (3D) structure) of a protein of interest. In some cases, a 2D protein array can be used to evaluate (e.g., characterize) protein-protein interactions (e.g., stable interactions vs. transient interactions). In some cases, a 2D protein array can be used to evaluate a binding domain in a protein of interest. In some cases, a 2D protein array can be used to evaluate (e.g., identify) binding targets and/or partners of a protein of interest.
