Electronic Design of a Semi-Automated Micromanipulator Cell Injection System

A cell microinjection system is a widely used tool in the domain of cell biology and it allows us to deliver a specific amount of substance into a cell using a fine tipped needle (or a microinjection pipette) under the observation of a microscope. Cell microinjection systems are widely used for delivering drugs to a single cell for the treatment of diseases, like Cancer, Alzheimer's, Sickle cell anemia and Cystic fibrosis etc., developing organs, like heart, lungs and kidney, and in-vitro fertilization. This paper surveys the state-of-the-art microinjection techniques and cell microinjections systems and proposes an electronic design for the semi-automated micro cell injection system, which works on the principle of capillary pressure microinjection (CPM). The distinguishing feature of the proposed system is its low cost without compromising on the accuracy or movement precision.
