Abstract: Disclosed are novel electrolytes, and techniques for making and devices using such electrolytes, which are based on compressed gas solvents. Unlike conventional electrolytes, disclosed electrolytes are based on “compressed gas solvents” mixed with various salts, referred to as “compressed gas electrolytes.” Various embodiments of a compressed gas solvent includes a material that is in a gas phase and has a vapor pressure above an atmospheric pressure at a room temperature. The disclosed compressed gas electrolytes can have wide electrochemical potential windows, high conductivity, low temperature capability and/or high pressure solvent properties.

Abstract: Methods, systems, and devices are disclosed for the identification of chemical agents and determination of their level of exposure using electrochemical detection and advanced signal processing. In one aspect, a method includes collecting a sample from a surface containing a chemical agent to an electrode on a sensor such that the chemical agent transfers on the electrode, detecting an electrochemical signal of the chemical agent on the electrode to transduce chemical information associated with the chemical agent to an electrical signal, processing the electrical signal to obtain electrochemical spectral signature data to identify the chemical agent and generating a series of coefficients of the electrochemical spectral signature data to reduce the data, and classifying the chemical information based on the series of coefficients among preselected data sets to determine a level of exposure to the chemical agent.

Abstract: Methods, systems, and devices are disclosed for providing test strip electrochemical sensors for rapid quantitative analysis of analytes in physiological fluids. In one aspect, an electrochemical sensor includes a substrate; an electrode contingent including a first electrode having a coating of carbon nanotubes (CNTs) and a second electrode on the substrate; and an entrapment layer formed on the first electrode to attach an enzymatic substance capable of causing a redox reaction in the presence of a target analyte of a fluid sample which produces a redox-active product, in which the entrapment layer is structured to include a conductive polymer film that is reversibly dopable to conduct charge carriers across the entrapment layer and at the first electrode. For example, the electrochemical sensor can be provided on a disposable test strip to quantify L-DOPA levels in whole blood, plasma, or serum samples.

Abstract: Living cells, such as red blood cells (RBCs) modified with functional micromotors with the aid of ultrasound propulsion and magnetic guidance. Iron oxide nanoparticles are loaded into the RBCs, where their asymmetric distribution within the cells results in a net magnetization, thus enabling magnetic alignment and guidance under acoustic propulsion. The RBC motors display efficient guided and prolonged propulsion in various biological fluids, including undiluted whole blood.
