SEMINAR:Computational Bionanodesign & Molecular Electronics..
The realization of nanoscale devices largely depends on our ability to control and manipulate both the molecular interactions and charge transport within and among molecules. The field of molecular electronics uses molecules as electronic components and has intriguing applications in a variety of fields, including storage devices, logic circuits, optoelectronics, and biosensors. Molecular electronics offer various fundamental advantages. First, the size of molecules used is in the realm of nanometers, and thus the device packing densities can be increased with lower cost, high efficiency, and low power dissipation. Second, one can use specific intermolecular interactions to form desired geometries via self-assembly in a bottom-up fashion. Therefore, various organic and inorganic molecules have been the subject of extensive research to engineer novel electronic components. For more than two decades, DNA/RNA has been at the forefront of molecular electronics research. Facilitated by the advance of synthetic biology, designer DNA with predetermined sequences can be readily synthesized for various applications (e.g., biosensors, single molecule transistors, DNA origami, DNA nanopores and DNA storage) in the emerging field of molecular electronics. However, the lack of control of charge transport significantly limits its application in nanoelectronics. In this talk, we describe how novel peptides and/or oligonucleotides can be designed with specific charge transport properties using novel computational/engineering approaches and give examples of their potential utilizations in technology and medicine.
