Dip pen nanolithography (DPN) is a method of creating nanoscale chemical patterns on surfaces using an atomic force microscope (AFM) probe. Until now, efforts to increase the process throughput have focused on passive multi-probe arrays and active arrays based on thermal bimetallic actuation. This paper describes the first use of electrostatic actuation to create an active DPN probe array. Elec...
In Computer-Aided-Drug-Design (CADD), the electrostatic interactions contribute strongly to the interaction between the drug-molecule and the target. Further, the Coulomb term is crucial for calculating the electrostatic contribution to the solvation energy. In spite of this, conventional Force Fields use the obsolete physical concept of point-monopoles (net atomic charges) and thus, are not ab...
This paper investigates the fault detection of a micro parallel plate capacitor subjected to nonlinear electrostatic force. For this end Thau observer, which has good ability in fault detection of nonlinear system has been presented and governing nonlinear dynamic equation of the capacitor has been presented. Upper and lower threshold for fault detection have been obtained. The robustness of th...
In this paper, we present a novel formulation for performing topology optimization of electrostatically actuated constrained elastic structures. We propose a new electrostatic-elastic formulation that uses the leaky capacitor model and material interpolation to define the material state at every point of a given design domain continuously between conductor and void states. The new formulation a...

Predictions of electrostatic double-layer interaction forces between two similarly charged spherical colloidal particles inside an infinitely long "rough" capillary are presented. A simple model of a rough cylindrical surface is proposed, which assumes the capillary wall to be a periodic function of axial position. The periodic roughness of the wall is characterized by the wavelength and amplit...
In previous work, I have proposed that nanoscale electrostatics plays a significant role in aster (spindle) assembly and motion, and in force generation at kinetochores and chromosome arms for prometaphase, metaphase and anaphase-A motions during mitosis. I have also discussed the possible role of electrostatics in anaphase-B cell elongation. Recent experimental studies have revealed that force...
