Amyloid-beta-sheet formation at the air-water interface.
An amyloid(1-40) solution rich in coil, turn, and alpha-helix, but poor in beta-sheet, develops monolayers with a high beta-sheet content when spread at the air-water interface. These monolayers are resistant to repeated compression-dilatation cycles and interaction with trifluoroethanol. The secondary structure motifs were detected by circular dichroism (CD) in solution and with infrared refle...
متن کاملOrganic ions at the air/water interface
Direct spectroscopic evidence of the presence of organic phenolate ions at the air/aqueous interface has been established using the nonlinear spectroscopic technique of vibrational sum frequency generation (SFG). By probing the phenol C–OH and the phenolate C–O vibrational stretches, which occur in the range of 1200–1300 cm and are distinguishable, we have succeeded in determining the identitie...
متن کاملHydrated electrons at the water/air interface.
The dynamics of hydrated electrons at the water/air interface are investigated using time-resolved second-harmonic generation spectroscopy. Initial solvation occurs in approximately 1 ps, and the electron remains at the interface for >750 ps. The location of the electron relative to the dividing surface is investigated using surfactants, which show that the electron is hydrated in the interfaci...
متن کاملBacterial Accumulation at the Air-Water Interface
Accumulation at the air-water interface of four bacterial strains with different hydrophobicities was studied. To exclude system influences, both a static batch system and a dynamic system involving rising bubbles were used. All bacteria accumulated at the air-water interface in both systems. Generally, attachment to the air-water interface increased with bacterial surface hydrophobicity. Accum...
متن کاملIons at the air/water interface.
In a recent review of this topic [B.C. Garett, Science 303 (2004) 1146] the emphasis was on some recent experiments, in which it was found that some anions accumulate at the air/water interface and not in the bulk, as usually happens to the cations, and on some simulations which explained those positive surface adsorption excesses. Because a large number of these experiments could be explained ...
