Abstract: A dispensing system can include a container including multiple channels, and each channel can be capable of containing an amount of a liquid. The dispensing system can include a well plate including multiple wells, and each well can be configured to align with a respective channel of the container. The dispensing system can include a plunger including multiple protrusions, and each protrusion can be configured to be inserted into a respective channel of the container. Movement of the plunger toward the container can force each protrusion to be inserted into the respective channel of the container thereby driving liquid from the respective channel and into a respective well of the well plate.

Abstract: An optical spectroscopy probe including an optical fiber having a distal tip and a microfluidic filtering chamber attached to the distal tip of the optical fiber, the chamber comprising a microfluidic membrane configured to enable liquid to enter the chamber but prevent particles from entering the chamber. Method for fabrication of same.

Abstract: A mobile phone-based system for ELISA (MELISA). The MELISA system can perform all steps of ELISA procedure and output hormone concentration values. The system includes a heater that keeps the temperature required for sample incubation, illumination system for sample image capturing, and a digital camera system. All components are enclosed in a dark box to create optimal light conditions for image capturing. After sample images are captured, they are digitally processed, and hormone concentration values are reported based on colorimetric data from the samples. The system can be used to complete all steps of the assay, including incubation and reading. It is lightweight, can be fabricated at low cost, is portable, and can transfer test results via mobile phone. MELISA can be calibrated for accurate measurements of progesterone and has demonstrated successful measurements with the calibrated system.

Abstract: A system for hemolysis detection, where the system generally includes—individually or in combination—a containment apparatus for holding the blood sample and a software application for analyzing the blood sample. The containment apparatus houses the sample therein, and blocks out any light from penetrating the apparatus and reflecting off of the sample. In conjunction, the software application uses camera color for processing the color of the sample to determine the hemoglobin level in plasma based on the color.

Abstract: In one embodiment, a heating element includes a central particle and a plurality of plasmonic nanoparticles attached to the central particle, wherein the nanoparticles undergo plasmonic heating when exposed to near infrared light.

Abstract: A pixel includes a primary element and a secondary element. At least a portion of the primary element is deformable between two positions. In one position, the light source is reflected such that the observer observes a dark pixel. In the other position, the light is reflected such that the observer observes a bright pixel. Gray levels of light are viewable by varying between the two positions.

Abstract: An angle sensor, system and method employ a guided-mode resonance. The angle sensor includes a guided-mode resonance (GMR) grating and a resonance processor. The resonance processor determines an angle of incidence of a signal incident on the GMR grating. The resonance processor uses a guided-mode resonance response of the GMR grating to the signal to determine the angle of incidence. The angle sensing system includes the GMR grating, the resonance processor and further includes an optical source that produces the signal. The method includes providing a GMR grating, detecting a guided-mode resonance produced in the GMR grating when subjected to an incident signal, and determining an angle of incidence of the incident signal from one or both of a number of and a spectral distance between guided-mode resonances present in a response of the GMR grating to the incident signal.
