Single-Use Sensor Strips for Reliable Field Analysis of Gunshot Residue

Abstract

This report summarizes our activity over the past 24 months of the project titled Single-Use Sensor Strips for Reliable Field Analysis of Gunshot Residue . Our team s accomplishments over the past two years include developments made on four major thrusts: (1) fabrication and assay optimization of the GSR sensor strip to demonstrate the simultaneous measurement of several GSR relevant heavy metals using a short assay time, (2) integrated sample protocol with the sensor strip towards efficient collection and negligible contamination, (3) advanced signal processing towards successful data reduction and feature extraction, along with the generation of unique GSR fingerprint patterns and (4) design of hand-held analyzer to demonstrate a complete prototype containing the required electronics, power systems, along with advanced signal processing.
