| Public Description | Fabrication of nanochannels is attracting considerable interest due to its broad applications in nanobiotechnology and distinct advantages compared to more commonly used nanopores. Nanochannels allow for a slower translocation and multiple sensing spots along the channel which improves read-out resolution. However, they require optical and electrical accessibility which has proven difficult to provide. Purdue researchers have developed a novel fabrication technology for a nanofluidic channel that is simple and compatible with CMOS fabrication. Nano-scale electrical contacts are implemented on the channel and a glass cover allows real time microscopic examination. |
