Resistive pulse asymmetry for nanospheres passing through tunable submicron pores
Asymmetric resistive pulses caused by nanoparticles passing through tunable nanopores have been recorded and studied using a semianalytic physical model. Experiments used 220 nm diameter
Demonstration of Coulter counting through a cylindrical solid state nanopore
The technique known as a Coulter counting, or resistive-pulse sensing, can be used to measure the size of a nanoscale analyte as it passes through a fluidic constriction separating two reservoirs. We

Highly Charged Particles Cause a Larger Current Blockage in Micropores Compared to Neutral Particles.
TLDR
It is shown that highly charged hard spheres can cause a significant increase of the resistive-pulse amplitude compared to neutral particles of a similar diameter, and this finding is of crucial importance for sizing particles and characterizing their surface charge properties.
Anomalous mobility of highly charged particles in pores.
TLDR
It is shown that the mobility of highly charged carboxylated particles decreases with the increase of the solution pH due to an interplay of three effects: ion condensation, formation of an asymmetric electrical double layer around the particle, and electroosmotic flow induced by the charges on the pore walls and the particle surfaces.
The electrical sensing zone method of particle size distribution determination (the Coulter principle)
The Coulter technique is a method of determining the number and size of particles suspended in an electrolyte by causing them to pass through a small orifice on either side of which is immersed an
Diffusion and Trapping of Single Particles in Pores with Combined Pressure and Dynamic Voltage
In this article we report resistive-pulse experiments with polystyrene particles whose transport through pores is controlled by modulating the driving voltage during the process of translocation.
Experimental Investigation of Dynamic Deprotonation/Protonation of Highly Charged Particles
Single pores have found application in detecting and characterizing individual objects such as cells, particles, and even individual molecules. The experimental approach, called resistive-pulse
A variable pressure method for characterizing nanoparticle surface charge using pore sensors.
TLDR
The efficacy of this variable pressure method was demonstrated for a range of carboxylated 200 nm polystyrene nanoparticles with different surface charge densities, and the sequence of increasing zeta potential for different particle types agreed with conductometric titration.

Counting and Sizing of Submicron Particles by the Resistive Pulse Technique
The resistive (Coulter) method of counting and sizing particles in a conducting fluid has been extended to polystyrene spheres 900 A in diameter, with a present detection limit near 600 A, through
Flow Around a Spheroid in a Circular Tube
The problem of the ideal fluid flow around a spheroidal obstacle inside a coaxial cylinder is solved by a slight variation of the method described earlier [W. R. Smythe, Phys. Fluids 4, 756, (1961)].
Novel Filter for Biological Materials
Thin plastic sieves with precisely controlled hole size and density can be made by irradiating plastic films with fission fragments and etching out the material traversed by the fragments. These

This paper gives a solution of Laplace's equation for prolate and oblate spheroids inside a coaxial cylinder on which the potential is either zero or such that its normal derivative is zero. The
Demagnetizing Factors of the General Ellipsoid
Charts and tables of the demagnetizing factors of prolate and oblate spheroids are readily available; however, demagnetizing factors of ellipsoids of three different axes are incompletely tabulated
