• Dielectrophoresis (DEP) force dependence on microelectrode array size parameters is presented in this work. Using finite element method numerical calculations for golden interdigitated electrodes have been performed and DEP force at nanometer heights dependence plots were made. Using theoretical modelling microelectrode width, spacing and thickness has been altered and gradient of electric field dependence plots have been analyzed. It was showed that electrode spacing reduction is the most effective way to achieve higher DEP forces. Also the influence of one size parameter on the gradient of electric field when the other two size parameters are being altered has been studied. It was determined that reduction of width below 10 µm when the spacing of the electrodes is less than 5 µm doesn't have any impact on the gradient of electric field. Ill. 6, bibl. 9 (in English; abstracts in English and Lithuanian). Baigtiniii elementu metodu nagrinejama dielektroforezes jegos priklausomybe nuo mikroelektrodu dydzio parametru Darbe gautos dielektroforezes jegos priklausomybes nuo mikroelektrodu plocio, tarpo ir aukscio. Sudaryti atitinkami priklausomybiu grafikai ir atlikta ju analize. Nagrinejamos elektrodu strukturos, kuriu ilgis ir tarpas tarp elektrodu keiciamas nuo 5 iki 20 mikrometru, elektrodu masyvo aukstis keiciamas nuo 100 iki 200 nanometru. Parodyta, kad mikroelektrodu tarpo keitimas yra efektyviausias budas elektrinio lauko gradientui didinti. Taip pat isnagrineta kiekvieno dydzio parametro itaka dielektroforezes jegai, kai kiti du dydzio parametrai yra keiciami. Gautos atitinkamos priklausomybes ir padarytos isvados. Parodyta, kad elektrodu aukscio ir tarpo keitimas turi itakos plocio keitimo efektyvumui. Taikant baigtiniu elementu metoda, parodyta, kad, esant mazesniam negu penkiu mikrometru elektrodu tarpui, didesnis nei 10 mikrometru plocio mazinimas neturi jtakos dielektroforezes jegai.
