Bacterial migration along solid surfaces.
An in vitro system was developed to study the migration of uropathogenic Escherichia coli strains. In this system an aqueous agar gel is placed against a solid surface, allowing the bacteria to migrate along the gel/solid surface interface. Bacterial strains as well as solid surfaces were characterized by means of water contact angle and zeta potential measurements. When glass was used as the s...
متن کاملChemical Processes on Solid Surfaces
Nobel Prize® and the Nobel Prize® medal design mark are registered trademarks of the Nobel Foundation 1 Introduction The Nobel Prize in chemistry for 2007 is awarded to Gerhard Ertl for his thorough studies of fundamental molecular processes at the gas-solid interface. When a small molecule hits a solid surface from a gas phase there are a number of possible outcomes. The molecule may simply ei...
متن کاملSelf-assembly at solid surfaces
The spontaneous formation of highly ordered amphiphilic monolayers on solid surfaces by adsorption from organic solutions at the liquid–solid interface was first reported in the seminal work of W. A. Zisman and co-workers in the mid-20th century [1]. In that work, attention was focused on the remarkable wetting properties of such monolayers, which were not only hydrophobic, but also oleophobic,...

متن کاملUnderstanding enzyme action at solid surfaces.
In solid-phase synthesis, there is interest in using enzymes that normally act on dissolved substrates. It is normally observed that rates and yields are substantially reduced when the usual substrates are covalently attached to a solid particle. Recently, there has been some progress in understanding the reasons for this, and hence how to improve behaviour. Diffusion of enzyme molecules into s...
