Abstract

This Small Business Technology Transfer Phase I project will develop a new type of nanostructured substrate for applications in arsenide detection using surface enhanced Raman spectroscopy (SERS). Arsenic is a well known toxic chemical which exists in both nature and industrial processes, and its detection and monitoring at very low concentration is highly desired. SERS, which relies on Raman signal enhancements for molecules in close contact with noble metal nanostructures, can provide essential information for detection and identification of biological and chemical materials including arsenic. However, its application has been obstructed primarily by the lack of SERS substrates that can be fabricated with high performance and in a repeatable fashion. The proposed research aims to resolve this issue by developing SERS substrates through designing, fabricating, and testing a new nanostructured noble metal substrate.
