Abstract: Disclosed are sensor materials and sensors prepared from thermoplastic polymers filled with 2D nanoparticles. The thermoplastic polymers filled with 2D nanoparticles are prepared by a method in which a thermoplastic polymer is melt-blended with at least one layered material under shear sufficient to exfoliate the layered material in the thermoplastic polymer until 2D nanoparticles are formed, to provide covalently linked 2D nanoparticle-filled thermoplastic polymers. Such filled thermoplastic polymers have utility for preparing various types of sensors which are useful in a variety of practical applications and devices.

Abstract: Disclosed is a concise, inexpensive and scalable method for preparing elastomers filled with conductive 2D nanoparticles. The method comprises independently filling elastomer polymer precursors and/or corresponding elastomer polymer curing agents or their precursors with conductive 2D nanoparticles by shear exfoliation of a layered material, followed by mixing the two components and curing to form the elastomer. Such filled elastomers have utility in preparing various types of sensors which are useful in a variety of practical applications and devices.

Abstract: Sensors employing elastomers enhanced with electrically conductive 2D nanoparticles are provided. The nanoparticles are formed by applying shear to layered materials present in elastomer precursors (e.g., elastomeric monomer(s) and/or curing agent(s)). Subsequent exfoliation of the layers occurs directly within the precursor and/or curing agent. The cured elastomer nanocomposites can be employed for electrochemical sensing, flexible touchpads, pressure sensors, and wireless sensors, amongst other applications.

Abstract: Devices and methods for selectively accessing tissue for sensing or drug release are provided. A device includes an array of wells formed in a substrate supporting a plurality of membranes. Each membrane is disposed at a well opening of one of the wells of the array. The device further includes an actuator and electronics configured to control the actuator to supply a vibration through the substrate. The supplied vibration is configured to selectively rupture one of the plurality of membranes at a defined timepoint to selectively give access to tissue through a well opening.

Abstract: Sensors and methods of fabricating sensors for detecting an analyte, such as a cytokine are provided. A sensor includes a porous, hydrophilic substrate, throughout which a coating comprising a mixture of graphene and a conductive polymer is disposed. The sensor further includes a sensing area, at which the coating is functionalized with at least one molecule that provides for a binding interaction with the analyte, and a contact area. The contact area includes an electrode in operative arrangement with the sensing area to provide a signal indicative of an impedance.
