Electrokinetic surface characterization of biomedical polymers — a survey

Continuous flow synthesis of ultrasmall gold nanoparticles in a microreactor using trisodium citrate and their SERS performance

“…8. For the concentration of 5 Â 10 À6 M, the ''signature" bands Werner et al (1999). b Bismarck et al (1999).…”

Electrokinetic Potential and Other Surface Properties of Polymer Foils and Their Modifications

“…by chitosan [16], biphenyldithiol [17], polyethyleneglycol [18] or by gold coatings [14,17]. It can also be used in research of textiles, where -potential plays an important role in the electrical characterization in wet processing [7], hairs [19], biomaterials [20] and glass [21,22] and as a parameter of colloid stability (paints, printing inks, drilling muds etc.). Zeta potential of human enamel is of physiological importance since it affects interactions between enamel surfaces and the surrounding aqueous medium of saliva [23].…”

Characterisation of ‘wet’ polymer surfaces for tissue engineering applications: Are flat surfaces a suitable model for complex structures?

“…Streaming potential [20] and contact angle measurements [21] have become standard tools for studying the chemical properties and surface energy of polymer surfaces, respectively. Electrokinetic techniques are employed for in depth study of interfacial charge characteristics of polymer materials, highlighting (a) the interfacial charge formation process, (b) the derivation of acid-base characteristics of surface functions, and (c) the correlation between hydrophobicity and charge formation of the polymer-electrolyte interface by preferential ion adsorption, without dissociating functions [22]. Electrokinetic (streaming potential) measurements have also been used to study a wide variety of biomaterials ranging from hemodialysis membranes to cardiovascular implants [22,23].…”

Electrokinetic (streaming potential) measurements have also been used to study a wide variety of biomaterials ranging from hemodialysis membranes to cardiovascular implants [22,23]. In addition, streaming potential measurements allow the investigation of the adsorption of proteins on polymeric substrates under in situ conditions [25,26].…”
