AC Electrokinetic: Colloids and Nanoparticles by Hywel Morgan, Nicolas G. Green

By Hywel Morgan, Nicolas G. Green

Biologists, physicists and engineers are operating jointly to make ever-smaller units able to learning the houses of tiny organic debris. utilizing nano-electrodes, encapsulated in a tool with dimensions of some hundred millionths of a meter, it's now attainable to control and seize unmarried nano-scale organic debris resembling an epidemic. The accurately managed electrical fields generated in the equipment can be utilized to capture unmarried debris in field-cages or separate varied viruses from one another, for instance.

This ebook is an advent to the technological know-how at the back of the hot know-how, and explains how the electrical box interacts with the debris. It describes how those micro-systems are synthetic and the way they're used to review homes of the debris. The authors supply a complete remedy of the underlying ideas and governing concept for the AC electrokinetic habit of debris, assessment the present cutting-edge in AC electrokinetic manipulation and characterization of debris, and supply chapters on simulation, equipment layout and fabrication.

Sample text

As described in Chapter One, in particle AC electrokinetics a dipole moment forms due to the action of a field on a polarisable particle. In a non-uniform electric field the force imbalance on the dipole moves the particle. −Q +Q d Fig. 3 The equipotentials (dashed), electric field lines (dotted) and electric field vectors (black arrows) around a dipole consisting of a negative and a positive charge. The grey arrow between the two charges indicates the vector d and the direction of the dipole moment.
