Abstract

Apparatuses and methods for in situ detection of a trace amount of an analyte are disclosed herein. In a general embodiment, the present disclosure provides a surface-enhanced Raman spectroscopy (SERS) insert including a passageway therethrough, where the passageway has a SERS surface positioned therein. The SERS surface is configured to adsorb molecules of an analyte of interest. A concentrated sample is caused to flow over the SERS surface. The SERS insert is then provided to a portable Raman spectroscopy system, where it is analyzed for the analyte of interest.

Portable apparatus for separating sample and detecting target analytes

Patent Renzi, Ronald F [Tracy, CA]; Wally, Karl [Lafayette, CA]; Crocker, Robert W [Fremont, CA]; ...

Portable devices and methods for determining the presence of a target analyte using a portable device are provided. The portable device is preferably hand-held. A sample is injected to the portable device. A microfluidic separation is performed within the portable device and at least one separated component detected by a detection module within the portable device, in embodiments of the invention. A target analyte is identified, based on the separated component, and the presence of the target analyte is indicated on an output interface of the portable device, in accordance with embodiments of the invention.

Detection of counterfeit and compromised devices using system and function call tracing techniques

Patent Babun, Leonardo; Aksu, Hidayet; Uluagac, A. Selcuk

Frameworks, methods, and systems for securing a smart grid are provided. A framework can include data collection, call tracing techniques, and preparing call lists to detect counterfeit or compromised devices. The call tracing techniques can include call tracing and compiling all system and function calls over a time interval. The framework can further include data processing, in which a genuine device is identified and compared to unknown devices. A first statistical correlation can be used for resource-rich systems, and a second statistical correlation can be used for resource-limited systems. Threats of information leakage, measurement poisoning and store-and-send-later can be considered.

Portable chemical detection system with intergrated preconcentrator

Patent Baumann, Mark J.; Brusseau, Charles A.; Hannum, David W.; ...

A portable system for the detection of chemical particles such as explosive residue utilizes a metal fiber substrate that may either be swiped over a subject or placed in a holder in a collection module which can shoot a jet of gas at the subject to dislodge residue, and then draw the air containing the residue into the substrate. The holder is then placed in a detection module, which resistively heats the substrate to evolve the particles, and provides a gas flow to move the particles to a miniature detector in the module.
