| 摘要 |
<p>A method whereby first biological entities are recognized by way of second biological entities able to bind to the first (or the first to the second), including the steps of binding first biological entities to a surface comprising an array of first electrodes selectively energizable and addressable at least in part, positioned facing at least one second electrode, bringing the second biological entities into contact with the first, these second biological entities and possibly the first being moved by means of dielectrophoretic cages generated between the electrodes, and sensing any binding activity between at least a portion of the first and of the second biological entities, preferably utilizing radiation at a first frequency to excite fluorophore groups bound to the second biological entities and detecting the emission of fluorescence at a second frequency by means of optical sensors integrated into the electrodes, the biological entities preferably being concentrated on the electrodes by the fusion of dielectrophoretic cages.</p> |
