Abstract

Studies of individual cells via microscopy and microinjection are a key component in research on gene functions, cancer, stem cells, and reproductive technology. As biomedical experiments become more complex, there is an urgent need for robotic systems to: improve cell manipulation, increase throughput, reduce lost cells, and improve reaction detection. Automation of these tasks using visual servoing creates significant benefits for biomedical laboratories including repeatability of experiments, higher throughput, and a controlled environment capable of operating 24 hours a day. In this work the design and development of a new five degree-of-freedom biomanipulator designed for single-cell microinjection, is described. The biomanipulator employs three degrees of linear motion and two degrees of rotation. This provides the ability to manipulate/micro-inject cells at varying orientations, thereby increasing flexibility in dealing with complex operations such as injecting clustered cells. The capability of the biomanipulator is shown with preliminary experimental results using mouse myeloma cells.
