In this research, a new method for the self-assembly of carbon nanotubes (CNTs) using magnetic capturing and fluidic alignment has been developed and characterized. In this new method, the residual iron (Fe) catalyst at one end of the CNT was utilized as a self-assembly driver to attract and locate the CNT using magnetic forces, while the assembled CNT was aligned by the shear force induced from the fluid flow through the assembly channel. As an application of the CNT-assembled electrode to a functional device, an on-chip optical immunosensor using CNTs with a photovoltaic polymer coating has been proposed, developed, characterized and applied for the detection of a cardiac biomarker in this work. An individual CNT was assembled on a titanium (Ti) electrode and coated with a photovoltaic polymer, and then insulated with Parylene. The on-chip chemiluminescent immunoassay was directly performed onthe CNT photodetector for the detection of Cardiac Troponin T (cTnT). |
