ABSTRACT: TOWARDS MOLECULAR CONDUCTORS: ADVANCES IN CHARGE TRANSPORT THROUGH INDIVIDUAL DNA AND DNA-BASED MOLECULES

We would like to present the abstract of our keynote speaker – Danny Porath – who is a professor in the institute of chemistry and center for nanotechnology of the Hebrew University. He is also serving as the Vice Dean for research of the Faculty of Science at the Hebrew University and he is the international ambassador of “The COINS 2018”!

DNA is primarily and with no doubt the most important biological molecule. Its double-strand recognition, as well as the ability to control its sequence and manipulate its structure open a multitude of ways to make it useful for molecular electronics. Step by step we improve the synthesized constructs and the measurement methods of single DNA-based molecules. In this lecture I will review the field and report on our progress in producing and measuring DNA-based building blocks towards the construction of DNA-based programmable circuits.
