Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.

Abstract: A memristive device includes: a first electrode; a second electrode; a memristive matrix interposed between the first electrode and the second electrode; a porous dopant diffusion element in physical contact with the memristive matrix and in proximity to the first electrode and the second electrode; and a first mobile dopant species which moves through the porous dopant diffusion element in response to a programming electrical field. A method for using a memristive device having a porous dopant diffusion element includes applying a voltage bias to generate a programming electrical field such that dopants move through the porous dopant diffusion element, thereby changing the distribution of dopants within a memristive matrix to form a first state; removing the voltage bias, the dopants being substantially immobile in the absence of the programming electrical field; and applying a reading energy to the memristive device to sense the first state.
