Introduction. The electrical and electrostatic phenomena that take place in tissues, organs and body fluids of living organisms and man have been the issue of numerous publications in the medical literature for a decade. This applies not only to clarification of the pathogenesis of diseases but also the procedures and treatments.
Aim. The aim of this study was to determine the zeta potential of collagen-fibrin TachoComb surgical dressing and oxidized regenerated cellulose Surgicel–Fibrillar preparation in blood and alveolar bone.
Materials and methods. The study was conducted in Department of Ceramics and Biomaterials, Institute of Electrical Engineering in Wroclaw. The measurements of zeta potential were conducted by means of Zetasizer 2000 device produced by Malvern Instruments (UK).
Conclusions. The electrokinetic zeta potential of pH and temperature function in both tested haemostatic agents has negative charge. The zeta potential of pH function for TachoComb ranges from -15.2 (+ -12)mV to -9.8 (+ -0.9) mV, for Surgicel-Fibrillar the average values are 17.5mV. The values of zeta potential of temperature function for TachoComb were slightly higher, on average 15.9 mV, while for the Surgicel-Fibrillar ranged from -16.2 (+ - 1.3) to -22 mV, 0 (+ -1.2) mV.
