One of the largest global centers for nanotechnology, Albany NanoTech is home to the College of Nanoscale Science and Engineering (CNSE) and the New York State Center of Excellence in Nanoelectronics (NYSCEN) of the University at Albany–State University of New York. Its 450,000 square foot complex, including the only 200mm/300mm wafer facilities in the academic world, encompasses nanoelectronics, system-on-a-chip technologies, biochips, optoelectronics and photonics devices, closed-loop sensors for monitoring, detection and protection, and ultra-high-speed communication components.

A major focus for Professor Geer's research group is in the area of nanometrology—developing novel processes to quantitatively measure fundamental properties of nanoscale structures and devices. For example, ultrasonic force microscopy and heterodyne force microscopy have been used to carry out near-field nanomechanical imaging for carbon nanotubes, nanobelts, and nanowires and map nanoscale variations in mechanical modulus in a variety of nanoelectronic test structures.

A second area of interest concerns investigations of self-assembling, DNA-based molecular wires and devices for next generation integrated circuits. This research focuses on manipulating the self-assembly of beta-sheet proteins to form nanoscale conductive structures suitable for molecular electronic applications. Dip-pen nanolithography is currently being applied to these materials to controllably deposit test structures suitable for electrical and structural characterization for prototypical molecular-electronic device architectures.
