Macromolecular Data Storage

Friday November 3, 2017
3:30 pm

 Presenter:  Masud Mansuripur, University of Arizona
 Series:  Physics and Astronomy Colloquium
 Abstract:  Many of the traditional problems in disk and tape data storage can be overcome if data-blocks were to be released from the confines of a disk (or tape) and allowed to float freely between read/write stations (i.e., heads) and permanent "parking spots." The heads and parking spots thus become fixed structures within an integrated chip, while the macromolecular data blocks themselves become the (mobile) storage media. In this scheme, a large number of read/write heads could operate in parallel, the heads and parking spots would be constructed (layer upon layer) in a truly 3-dimensional fashion, and individual nanometer sized molecules - strung together in a flexible macromolecular chain - would be used to represent the 0’s and 1's of binary information. We discuss the potential advantages of this alternative scheme for secondary data storage and, to demonstrate the feasibility of the concept, present results of experiments based on DNA molecules that travel within micro-fluidic chambers. Since our first proposals to develop macromolecular data storage systems, other groups have contributed to developments in DNA-based techniques for information storage and processing. In this presentation we will discuss the latest developments reported by other groups as well.
