Individual Blood‐Cell Capture and 2D Organization on Microarrays
2009
The image shows living B lymphocytes captured on a microcantilever-arrayed biochip. Antibodies targeting cellular antigens are pyrrole-modified and then electropolymerized into polypyrrole films on a gold surface. The arrayed feature size is close to a lymphocyte size and thus allows efficient cell capture and organization. Gold layers can thus be arrayed in a predetermined manner that gives access to organized blood cells on surfaces. Each line is separated from the other by 50 µm.
