Journal ArticleDOI
Concise review of mechanisms of bacterial adhesion to biomaterials and of techniques used in estimating bacteria-material interactions.
TL;DR: The theories that are reviewed are the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, the thermodynamic approach and the extended DLVO theory, which provide the basis for theoretical analysis of the receptor-ligand interactions.

A review on the wettability of dental implant surfaces II: Biological and clinical aspects
Rolando A. Gittens,Lutz Scheideler,Frank Rupp,Sharon L. Hyzy,Juergen Geis-Gerstorfer,Zvi Schwartz,Barbara D. Boyan +6 more
TL;DR: This review provides a general overview of the available information about the contact angle values of experimental and of marketed implant surfaces, some of the techniques used to modify surface wettability of implants, and results from in vitro and clinical studies.

Protein Resistance of Titanium Oxide Surfaces Modified by Biologically Inspired mPEG−DOPA
Jeffrey L. Dalsin,Lijun Lin,Samuele Tosatti,Janos Vörös,Marcus Textor,Phillip B. Messersmith +5 more
TL;DR: Peptide anchors containing three DOPA residues resulted in PEG surface densities higher than those achieved using several existing PEG immobilization strategies, suggesting that peptide mimics of mussel adhesive proteins may be useful for achieving high densities of protein-resistant polymers on surfaces.

Spectroscopic study of extracellular polymeric substances from Bacillus subtilis: aqueous chemistry and adsorption effects.
Anselm Omoike,Jon Chorover +1 more
TL;DR: Goethite-EPS spectra show emergent vibrations consistent with P-O-Fe bonding, which suggests a role of phosphodiester groups in the adsorption reaction, and ATR-FTIR spectroscopy shows complexation and dissociation of protons on acidic functional groups that result in alpha-helical protein conformation at pH < 2.6 and random coil (unordered) conformation on higher pH (>6.

Kara L. Menzies,Lyndon Jones +1 more
TL;DR: The impact of contact angle on the biocompatibility of tissue engineering substrates, blood-contacting devices, dental implants, intraocular lenses, and contact lens materials is reviewed.

Influence of interfaces on microbial activity.
TL;DR: It is concluded that so far neither experimental nor theoretical evidence exists for a direct influence of interfaces on microbial activity.
Journal ArticleDOI
Measurement of the surface free energy of bacterial cell surfaces and its relevance for adhesion.
TL;DR: An experimental technique is described to determine contact angles on bacterial layers deposited on cellulose triacetate filters to calculate interfacial free energies of adhesion of these bacteria from saliva onto tooth surfaces.

Hydrophobic interactions: role in bacterial adhesion
Mel Rosenberg,Staffan Kjelleberg +1 more
TL;DR: The aims of the present chapter are to present some relevant aspects of hydrophobic interactions, describe the methodology available for measurements related to bacterial cell-surface hydrophobicity and the parameters they may measure, and discuss investigations dealing with surface components that promote or reduce bacterial hydrophobia.

The Influence of Surface Free-energy on Planimetric Plaque Growth in Man
Marc Quirynen,Marina Marechal,Henk J. Busscher,Anton H. Weerkamp,J. Arends,P. Darius,D. van Steenberghe +6 more
TL;DR: The results indicated that the adherence of micro-organisms on pellicle-coated substrata was influenced by the material's s.f.e.; there was an association between the s.e. of the substrata and the supragingival plaque extension in vivo, and high surface free-energy substrata in the oral cavity attracted more micro- organisms than did low energetic materials.
