With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Virginia Commonwealth University will acquire an Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometer. This equipment will enhance research in a number of areas including a) electron transfer reactions between cytochrome c, cytochrome c oxidase and dioxygen; b) characterization of chemical dynamics in complex systems; c) biomimetic-supported catalysts for oxygen- and peroxide-dependent oxidations; d) assessment of antibody-based sensors for trace analysis of environmental contaminants; e) lanthanide(III) macrocyclic complexes as luminescent bio-markers; and f) resonance Raman of oxidized peroxidases. Mass spectrometry (MS) is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic, and organometallic molecules. The results from these studies will have an impact in a number of areas including environmental chemistry and biochemistry.
