The frontispiece 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, which give access to organized blood cells on surfaces. Each line is separated from the other by 50 µm. For more information, please read the Communication “Individual Blood-Cell Capture and 2D Organization on Microarrays” by Y. Roupioz, L. Nicu, et al., beginning on page 1492.
