| 摘要 |
The invention provides a sensor component for detecting an analyte, comprising a first electrode and a second electrode; an insulating substrate disposed between the first electrode and the second electrode; a plurality of conductive nodes disposed on a surface of the insulating substrate; and a plurality of connector molecules comprising two or more groups capable of forming a chemical bond with a conductive node or an electrode, which connector molecules are capable of displaying a change in an electrical property in response to interaction with an analyte. At least some of the connector molecules are bonded to one or more nodes, or to one electrode, and thereby form electrical junctions between separate nodes or between a node and an electrode. The electrical junctions form an electrical percolation network comprising at least one continuous pathway of connector molecules between conductive nodes which connects the first electrode and the second electrode. Preferably,the network is in the percolation region. The invention also relates to a process for producing a sensor component, and a sensor component obtainable by that process. The invention also provides devices comprising the sensor component of the invention, including a sensor, as well asuses of the sensor component of the invention and uses of the devices of the invention,for detecting analytes. |
