The convergence of nanotechnology with advanced molecular modeling has enabled radical new advances in single atom physics across diverse disciplines:  High-speed, high-density electroniques, molecular biosensors, energy conversion, etc.  This presentation explores the technologies involved in the generation of atomic manipulation and nanoscale devices.  More specifically, the unique fabrication processes required to realize a stochastic, nanopore sensor serves as a forum to discuss the anatomy of nanoscale innovations developed in the creation of new nanodevices and nanostructures. The nanopore sensor presented here consists of a 1nm-10nm nanopore fabricated in a thin (40nm) membrane and articulated with graphene like nanoelectrodes at the periphery.  DNA is electrophoretically driven through the nanopore and �tunneling� current between the electrodes is modified as different nucleotide sequence pass.  Single nucleotide counting has been achieved and will be presented, but focus is given to the fabrication methods and challenges realizing the nanopore device.
