A primary objective of modern biology is to understand the molecular mechanisms which underlie cellular functions and a crucial part of this task is the ability to manipulate and analyze individual cells. As a result of interdisciplinary research, microfluidics may become the forefront of analytical methods used by biologists. This technology can be used to gain unprecedented opportunities for cell handling, lysis and investigation on a single cell basis. This thesis presents the development of a microfluidic device capable of selecting individual cells and performing selective electrical lysis of the plasma membrane, while verifying intactness of the nuclear membrane. The device is fabricated by an improved photolithography method and integrates molten solder as electrodes for lysis by a DC electric field. Quantification of lysis is accomplished by video and image analysis, and measurement of the rate of ion diffusion from the cell.
