The invention is a novel and non-obvious design and implementation of an inductive sensor for quantifying magnetic particles. The invention parts way from the conventional methods of using wounded coils to a design that is compatible with an integrated circuit (IC) chip fabrication processes and/or printed circuit board (PCB) manufacturing. The increased accuracy from these fabrication methods provides a significant improvement to sensor sensitivity. In addition, the design of the inductive sensor enables easy integration with lateral flow assay (LFA) technology. The sensor can be applied to detect and quantify molecules to provide information on health, hazard or safety.

A method and a system for determining material-, size-, and morphology-dependent photothermal properties of particles dispersed in solutions, the method comprising using coherently detected pulsed THz radiation, tracking a temperature-dependent refractive index change of the particles dispersion in time and space, and correlating the temperature-dependent refractive index change of the particles dispersion in time and space to temperature values. A system comprises a source of electromagnetic radiation; a THz emitter; a THz detector; and a vessel containing a dispersion of particles, wherein the source of electromagnetic radiation is configured to emit electromagnetic radiation to excite the particles in the dispersion; the THz emitter is configured to send THz radiation to the vessel and the THz detector is configured to receives THz radiation returned by from the vessel.

A sensor system detects a presence or concentration of an analyte in a medium. The sensor system contains a sensor having a sensor head with a chamber. The sensor head has a permeable area through which the analyte can pass into the chamber when the sensor head contacts the medium. A cross-linked hydrogel fills the chamber, the hydrogel is configured to undergo a change in volume when contacting the analyte passed into the chamber which leads to a change in pressure in the chamber. A pressure sensor is configured to measure the pressure in the chamber for detecting the presence or concentration of the analyte.

A device includes a filter that enhances a beam profile of a received pulsed laser; a first optical element to direct the pulsed laser as a reference wave towards an optical sensor; an open cavity positioned between the first optical element and the optical sensor. The open cavity receives an aerosol particle, which enters the open cavity from any direction. The reference wave illuminates the aerosol particle. An illuminated particle generates and directs an object wave towards the optical sensor. A pixel array is connected to the optical sensor. The pixel array receives the reference wave and the object wave. The optical sensor creates a contrast hologram comprising an interference pattern of the illuminated particle. A processor creates an image of the illuminated particle based on the contrast hologram.
