Maintained by asgaris
Nanopore-based DNA sequencing is a unique, scalable technology, utilized to identify nucleotides (i.e., A, C, G, T) according to the pico-ampere-sized current fluctuations induced by the passage of a DNA strand through a nanopore. The main components of this technology fit in the palm of one’s hand and it has demonstrated the ability to process contiguous DNA strands well in excess of 100,000 nucleotides in length. There are at least two key parts to this, i) a multi-channel digital readout integrated circuit (DROIC), that amplifies, filters, and digitizes the current measurements from multitudes of arrayed nanopore sensors, and ii) a bioinformatics processing unit (BPU) that processes the gathered data in order to extract biologically relevant information. In this proposal, we endeavor to produce a chip that has both a DROIC and BPU in the same substrate. The intent of this effort is to introduce a technology that, by virtue of even more aggressive miniaturization will make DNA sequencing more mobile, cheaper, and more applicable to a broader array of applications.
