More Information
Summary:Provided herein is a new hybrid material system, mCNT, including magnetic carbon nanotubes for biological and medical sensing applications. In certain embodiments, the systems include magnetic material on the interior of carbon nanotubes (CNTs). The amount of magnetic particles inside CNTs may be such that mCNT can respond to small, low cost, portable magnet. The exterior CNT surface is kept intact for biomolecular attachments or other functionalizations. Performance enhancement with this novel material includes improved sensitivity, reduced response time, and reduced sample volume. According to various embodiments, the mCNTs are substrates for the adherence of molecules participating in these assays or as active sensing elements. Also provided are methods of fabricating two-dimensional mCNT and CNT networks on printed electrodes.
