“…In other words, it is a continuous, nondestructive monitoring technique. It was Vogler,6 reviewed by Schamberger and Gardella, 7 who outlined the importance of wettability, specifically tensiometric methods, in the field of interface characterization techniques used in analyzing biomaterial surfaces. Tensiometric tools meet the requirements of surface sensitivity and yield results that are relevant to the hydrated physiological environment.…”

As a result of inflammatory processes, plaque formation on dental titanium implants often leads to clinically pathogenic situations. This special biofilm formation on (bio)materials in contact with saliva is initiated by ionic and protein interactions. In this interfacial process, albumin becomes a main constituent of dental pellicle. Interfacial reactions change the surface characteristics. They determine the following steps of macromolecular adsorption and bacterial adhesion. This work focuses on the dynamic contact angle analysis (DCA), which is a tool for online measurements of dynamic changes of wettability without disturbing the interface during detection. Repeatability of the DCA method has been assessed according to the Bland and Altman method. The kinetics and equilibrium data of shifts in the wetting tension hysteresis indicate ionic influences at the titanium/bovine serum albumin (BSA) interface: the Ca-mediated increase of the BSA adsorption on titanium and the adsorption maximum at the isoelectric point (IEP) of BSA. Ti was surface modified by Teflon AF polymeric coatings. The result of the assessment gives reason to consider Teflon AF as a reference material for DCA repeatability studies. This surface modification caused drastic changes in the dynamic interfacial reactions. Shifts in the wetting tensions during DCA adsorption-desorption experiments clearly demonstrated the partially irreversible adsorption of BSA on Teflon AF. In contrast, reversible adsorption behavior was detected on pure Ti surfaces. These findings strengthen the hypothesis that the analysis of dynamic changes in wetting tension and wetting tension hysteresis is a sensitive analytical method for the detection of dynamic interfacial changes at biomaterial/biosystem interfaces during the initial steps of biofilm formation.

“…In this test, the percentage of cell attachment increased as the wettability increased (or decreased in contact angle) with the addition of pectin (Table 3). The addition of pectin brings in the carboxylate groups and increases the surface oxygen content/oxygen functionalities which bind proteins more tightly and promotes cell attachment and growth (Schamberger & Gardella, 1994).…”

“…The functional groups of the dishes largely influenced wettability, and then the surfaces of Culture PS and Collagen PS indicate hydrophilicity (Table 1). Further, it is known that chemical modifications of the surfaces of cell culture substrates largely influence cell adhesion [55][56][57][58]. Therefore, the functional groups of the surface of Culture PS would play a role in cell adhesion similar to the functional groups of the collagen molecules.…”

Induced pluripotent stem (iPS) cells have attracted worldwide interest. However, there have been only a few studies investigating effective culture substrates for feeder-free culturing for the maintenance of iPS cells. In this study, we cultured mouse iPS cells under feeder-free conditions on carbon nanotube (CNT)-coated dishes and then evaluated the colony morphology and differentiation state of the cells on the dishes.After 5 d of cultivation in a medium containing 15% fetal bovine serum (FBS) and leukemia inhibitory factor (LIF), the colonies on thick films of multi-walled CNTs (MWCNTs) were observed to be hemiround; further, the cells expressed early undifferentiation markers. On the other hand, the colonies on a cell culture polystyrene dish and a collagen-coated polystyrene dish showed indistinct outline and spread well, and most spreading cells only weakly expressed early undifferentiation markers. These results indicate that the thick films of MWCNTs could maintain hemiround colonies and undifferentiated state of mouse iPS cells cultured under feeder-free conditions.
