The influence of electrostatic forces on protein adsorption

Biocidal action of ozone-treated polystyrene surfaces on vegetative and sporulated bacteria

“…Whereas PS surfaces treated with O 3 degrade the enzyme expression as we just showed, PS surfaces modified by UV-O 3 treatments are reported to enhance proliferation and protein expression [2,6]. Moreover, some functional coatings used to improve the spreading and growth of certain cells and to immobilize biomolecules (enzymes, peptides .…”

“…Understanding the relationship between cells and the physico-chemical properties of surfaces with which they interact (such as wettability, functional groups, topography) is, in fact, essential for the optimisation of cell adhesion, their spreading, and growth thereon [1]. Improved cellular attachment [3] is promoted by certain functional groups, which at the same time increase hydrophilicity, favouring the adsorption or adhesion of proteins [6]. For example, surface modifications with UV/O 3 [1] or with plasmas such as corona discharges [2] can increase proliferation and protein expression of cells or enhance their culture process.…”

Adsorption, immobilization, and activity of β-glucosidase on different soil colloids

“…In a study of the influence of electrostatic forces on protein adsorption [34], atomic force microscopy (AFM) was used to measure the electrostatic forces on the sorption of human serum albumin by UV-ozone-modified polystyrene. Results show that the electrostatic double force, introduced in an electrolyte near a charged surface, is an important driving factor (attractive or repulsive) for the process of protein adsorption onto a surface.…”

Detection of Protein Adsorption on Hydroxyapatite Using Electromagnetic Sensors

“…The analysis of protein adsorption onto HA is of great interest since the adsorption of protein to materials has an effect on the cell attachment, migration, and proliferation. Protein adsorption depends on the chemical and physical properties of a surface such as topography [3], surface charge [4] and chemical composition [5]. The challenge of a better understanding of protein adsorption mechanisms resides in a better knowledge of the material's properties.…”
