Microbial colonization of medical devices is a widespread problem that tests the limits of conventional analytical methods. Successful analytical endeavors require collaboration between clinicians, microbiologists, biomedical engineers, and analytical chemists.
Hydrogels are an increasingly important class of medical device materials that enable diverse and unique function, but can also be subject to significant biofouling and contamination. Although it is challenging to accurately quantify protein biofouling in hydrogels, spectroscopic detection of fluorescently labeled proteins is one method with the potential… (More)

Acutely dissociated rat brain cells were loaded with the magnesium-sensitive fluorescent dye furaptra. Stimulation with varying concentrations of GLU + 1 microM GLY produced a concentration-dependent increase in free intracellular magnesium ([Mg2+]i) that was not dependent on the presence of extracellular Mg2+. Ethanol (50 mM) did not significantly inhibit… (More)
