“…While the adsorption of molecules on polarized surfaces seems to be quite complex, the general notion that molecular interaction with the surfaces might depend on the fields present is supported by the observation that in the region of the ferroelectric domain boundaries the photo-reduction rate of AgNO 3 , HAuCl 4 , Pt (NO 3 ) 2 and other compunds is increased [23,[36][37][38][39]. In addition it was found that nanowires of pure Ag, Au and Pt were grown along the predefined 180 0 ferroelectric domain walls on c-cut congruent LiNbO 3 Less was so far known on interaction of cells with patterned, polarized substrates. Polarization-specific adhesion of cells does seem to occur under isothermal conditions and with minimal optical excitation, but cannot be attributed to the effect of pyroelectric or photoinduced charge [17].…”

“…Especially for motile microorganisms, surface charge affects adhesion and extended Derjaguin, Landau, Verwey, Overbeek (DLVO) theory, in conjunction with electrostatic interactions, are used to describe observed experimental trends [1,[3][4][5][6]. A series of studies by the Whitesides group show that an overall electrically neutral surface seems to be a prerequisite for an inert surface [7,8].…”

Adherent cells avoid polarization gradients on periodically poled LiTaO3 ferroelectrics

The response of fibroblast cells to periodically poled LiTaO3 ferroelectric crystals has been studied. While fibroblast cells do not show morphological differences on the two polarization directions, they show a tendency to avoid the field gradients that occur between polarization domains of the ferroelectric. The response to the field gradients is fully established after one hour, a time at which fibroblasts form their first focal contacts. If suspension cells, with a lower tendency to establish strong surface contacts are used, no influence of the field gradients is observed.

“…A few decades ago, a paper on bacterial adhesion to surfaces typically would either commence with the statement (15) "bacterial adhesion to surfaces is mediated by highly specific, stereo-chemical interactions between complementary components on the interacting surfaces" or (16,24) "bacterial adhesion is mediated by a complicated interplay between attractive Lifshitz-Van der Waals forces and repulsive or attractive electrostatic and acid-base forces, originating from the interacting surfaces." Generally, the "specific" approach was favored by microbiologists and biochemists, while physico-chemists usually took a "nonspecific" approach.…”

2Bacteria adhere to surfaces by virtue of their interaction forces with a substratum surface. A few decades ago, a paper on bacterial adhesion to surfaces typically would either commence with the statement (15) "bacterial adhesion to surfaces is mediated by highly specific, stereo-chemical interactions between complementary components on the interacting surfaces" or (16, 24) "bacterial adhesion is mediated by a complicated interplay between attractive Lifshitz-Van der Waals forces and repulsive or attractive electrostatic and acid-base forces, originating from the interacting surfaces." Generally, the "specific" approach was favored by microbiologists and biochemists, while physico-chemists usually took a "nonspecific" approach.The two approaches were reconciled with each other (7, 8) by the realization that both interactions originate from the same, fundamental physico-chemical forces (Lifshitz-Van der Waals, electrostatic, and acid-base interaction) (37). Nonspecific, Lifshitz-Van der Waals interactions operate over longer distances (several tens of nanometers) and originate from all atoms in the interacting entities. The summation of the relatively weak pairwise interactions between all atoms in an adhering bacterium and a substratum yields the final interaction force, similar to the origin of the gravitational force of the earth. Specific interactions, making up for molecular recognition between ligand and receptor molecules, operate over spatially well-confined stereochemical regions, established for instance by interactions between acid, electron-accepting and basic, electron-donating groups or oppositely charged domains, at close approach (up to several nanometers).Characterization of the bacterial cell and substratum surfaces in terms of their zeta potentials and surface free energies (from measured contact angles with liquids) offers the possibility to calculate the electrostatic and Lifshitz-Van der Waals contributions to the interaction force between two entities in an approach called the DLVO (Derjaguin, Landau, Verwey, and Overbeek) theory (5, 16). In the so-called "extended DLVO" theory (38), acid-base interaction forces are accounted for in addition to Lifshitz-Van der Waals and electrostatic forces. Application of physico-chemical theories toward explaining bacterial adhesion to surfaces has not always been successful, not even adhesion to inert (nonbiological) surfaces. After evaluating over 250 references, Bos et al. (5) concluded that the only general conclusion to be drawn was that negatively charged bacteria adhere more rapidly to a positively charged than to a negatively charged substratum surface.

“…Consequently, the force of interaction depends on physiochemical parameters such as surface-free energy and charge density (7)(8)(9)(10)(11). The propensity of bacteria to adhere onto surfaces has been estimated by counting the number of bacteria that remain attached to surfaces following incubation for a specified length of time (5,12).…”

Bacterial adhesion and the subsequent formation of biofilm are major concerns in biotechnology and medicine. The initial step in bacterial adhesion is the interaction of cells with a surface, a process governed by long-range forces, primarily van der Waals and electrostatic interactions. The precise manner in which the force of interaction is affected by cell surface components and by the physiochemical properties of materials is not well understood. Here, we show that atomic force microscopy can be used to analyze the initial events in bacterial adhesion with unprecedented resolution. Interactions between the cantilever tip and conf luent monolayers of isogenic strains of Escherichia coli mutants exhibiting subtle differences in cell surface composition were measured. It was shown that the adhesion force is affected by the length of core lipopolysaccharide molecules on the E. coli cell surface and by the production of the capsular polysaccharide, colanic acid. Furthermore, by modifying the atomic force microscope tip we developed a method for determining whether bacteria are attracted or repelled by virtually any biomaterial of interest. This information will be critical for the design of materials that are resistant to bacterial adhesion.Bacterial adhesion onto inanimate surfaces is a critical issue in processes ranging from the biofouling of industrial equipment to dental decay to infections of biomaterials for medical use. Bacterial infections associated with the formation of biofilms refractile to antibiotic therapy is one of the main reasons for the failure of devices such as catheters, vascular grafts, joint prostheses, and heart valves (1-3). The first step in bacterial adhesion is the immediate attachment of bacteria onto a substratum which is a reversible, nonspecific process (3-5). This initial interaction between bacteria and artificial surfaces is a key determinant in biofilm formation. If the approach of bacteria to a surface is unfavorable, cells must overcome an energy barrier to establish direct contact with the surface. Only when bacteria are in close proximity to the surface do shortrange interactions become significant. Thereafter, proteinligand-binding events mediated by a plethora of microbial adhesins and in some cases the production of extracellular polymers render the binding process practically irreversible (6).Initial bacterial attraction or repulsion to a particular surface can be described in terms of colloidal interactions. Consequently, the force of interaction depends on physiochemical parameters such as surface-free energy and charge density (7-11). The propensity of bacteria to adhere onto surfaces has been estimated by counting the number of bacteria that remain attached to surfaces following incubation for a specified length of time (5, 12). This approach is qualitative, time consuming, and has low sensitivity. Moreover, the resulting number of adherent bacteria is determined by multiple factors in addition to long-range attractive/repulsive interactions. A direct and ...
