The irreversible accumulation of biological material on synthetic surfaces ("biofouling") adversely affects for instance contact lenses, implantable biomedical devices, biosensors, water purification, transport and storage systems, and marine structures. It is shown here that proteins adsorbed on contact lenses can be detected directly, rapidly, and conveniently, with high sensitivity, by matrix-assisted laser desorption ionization (MALDI)-mass spectrometry. This new approach allows detection of minor (and major) proteinaceous constituents of biofouled layers on samples retrieved from clinical usage and in vitro protein adsorption studies, at levels substantially below monolayer coverage. Identification of the detected biological molecules can be done by comparison of the detected mass peaks with known protein molecular masses or with spectra recorded of pure compounds or by separate biochemical assays. The MALDI mass spectra recorded on different contact lenses contain peaks assignable to lysozyme and a number of smaller proteins. Such sensitive characterization of the early stages of biofouling enhances the understanding of protein/materials interactions and assists in designing guided strategies toward control of biological adsorption processes.
