Investigation of localization of DNA molecules using triangular metal electrodes with varying separation

Dependence of Shape and Geometry of Microelectrodes in Manipulating Polarizable Particles like DNA through Electro-kinetic Effects

“…Recently we studied in detail, through simulations how those minute bends of the electrodes and sharpness of the edges could affect the sites of the trapping points as well as its strength 26,27 . The electrode geometry used byus 26 is as shown in Fig.…”

“…The behaviour of the trapping points as a function of electrode separation, having a fixed convexity and properly scaled sharpness of tips are presented by Prasad 27 , et al Figures 12(a) and 12(b), respectively show the plot of the strength of the x-component of the force on a DNA molecule as a function of the parameter d for convex electrode and concave electrode. The convexity of the electrodes is maintained at a value of θ equal to 102° and its sharpness is kept constant by scaling down the size of the entire system for a decrease in d. From the Figs.…”
