| Abstract Scope |
Basuray group has developed a sensor platform called ESSENCE, a Shear-Enhanced, flow-through non-planar 3D Nanoporous Electrode. ESSENCE consists of a microfluidic channel packed with a transducer material like carbon nanotubes or other 2D materials, functionalized with capture molecules, surrounded by interdigitated electrodes. The porous electrode architecture enhances shear forces leading to high selectivity, enhanced electric field penetration due to the 3D electrode, and disrupts diffusive processes, leading to rapid measurements at a high frequency which leads to substantial enhancement in the signal-to-noise ratio and thus high sensitivity. Furthermore, unique chip architecture allows room temperature assembly with the transducer material easily exchanged to target different biomolecules, thus making ESSENCE a universal modular platform. For example, different 2D and 3D nanomaterials from graphene oxide, carbon nanotubes, and metal-organic frameworks can be used to tailor the platform to detect biological molecules or chemical moieties with high sensitivity and selectivity. |
