Interfacing Mass Spectrometry with New Materials Developed for Fast Targeted Analysis

Widespread and varied sources of environmental contamination has led to public concern about threats to the availability of clean water, air and food. Such pressures increase demands to test broadly and frequently to assure health, safety and resource quality. This context motivates my ongoing research program to develop sensitive, fast, simple analytical approaches necessary for high throughput screening of aqueous samples, which are also suitable for use in wastewater assessment and treatment programs. The work proposed here has two interrelated research themes: A) development of selective materials, principally molecularly imprinted polymer (MIP) films, for uptake of target analytes from aqueous solutions, and B) development of desorption electrospray ionization-mass spectrometry (DESI-MS) methods for direct interrogation of analytes in the selective sorbents.
