The Chemotactic Index for Spatial Gradient Sensing
Nicholas A. Licata
We consider the problem of quantifying the chemotactic efficiency of single cells as measured by the chemotactic index . Previous work in a model framework for direct sensing of…
Numerical and analytical approaches to an advection-diffusion problem at small Reynolds number and large Péclet number
Nathaniel J. Fuller, Nicholas A. Licata
Obtaining a detailed understanding of the physical interactions between a cell and its environment often requires information about the flow of fluid surrounding the cell. Cells mu…
Fluid flow enhances the effectiveness of toxin export by aquatic microorganisms: a first-passage perspective on microvilli and the concentration boundary layer
Nicholas A. Licata, Aaron Clark
A central challenge for organisms during development is determining a means to efficiently export toxic molecules from inside the developing embryo. For aquatic microorganisms, the…
The first passage problem for diffusion through a cylindrical pore with sticky walls
Nicholas A. Licata, Stephan W. Grill
We calculate the first passage time distribution for diffusion through a cylindrical pore with sticky walls. A particle diffusively explores the interior of the pore through a seri…
Self-assembling DNA-caged particles: nanoblocks for hierarchical self-assembly
Nicholas A. Licata, Alexei V. Tkachenko
DNA is an ideal candidate to organize matter on the nanoscale, primarily due to the specificity and complexity of DNA based interactions. Recent advances in this direction include…
How to build nanoblocks using DNA scaffolds
Nicholas A. Licata, Alexei V. Tkachenko
In recent years there have been a number of proposals to utilize the specificity of DNA based interactions for potential applications in nanoscience. One interesting direction is t…
