Development of Photoacoustic Spectroscopy for the Study of Biofilm Formation under Water.

摘要

A growing body of literature from a number of diverse scientific disciplines has documented that adsorption of a nonliving molecular organic conditioning film is the first event in the modification of a solid surface upon its immersion in any natural aqueous environment. The conditioning film has been described by a number of researchers using a variety of techniques. Baier (1972) and Baier and Weiss (1975) have used Multiple Attenuated Internal Reflection (MAIR) IR Spectroscopy and contact angle measurements to show how the solid surface energy is modified by adsorption of organics in human blood and in seawater. Neihof and Loeb (1974) and Loeb and Neihof (1975) have followed formation of the film in seawater by ellipsometry and by microelectrophoresis. Baier (1972) and Tosteson et al. (1978) have discussed the composition of the film and have shown it to consist of an initially adsorbed glycoprotein coating and a subsequent layer of mucopolysaccharide rich adhesive substances.
