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.
