Folding- and dynamics-based electrochemical biosensors

This seminar will cover the recent advances in the design and fabrication of folding- and dynamics-based electrochemical biosensors. These devices, which are often termed electrochemical DNA (E-DNA), aptamer-based (E-AB), and peptide-based (E-PB) sensors, are fabricated via direct immobilization of a thiolated and methylene blue (MB)-modified oligonucleotide or peptide probe onto a gold electrode. Binding of an analyte to the probe changes its structure and/or flexibility, which, in turn, influences the electron transfer between the MB label and the interrogating electrode.

In silico searches for (in)efficient electrocatalysts through chemical and material compound space

This talk will provide an overview of our group’s work using both standard and atypical high-performance computational chemistry modeling to elucidate atomic scale reaction mechanisms of catalytic reactions. I will introduce our toolkit of in silico methods for accurately modeling (electro)catalytic reactions in solvating environments. I will then present how in silico methods can be used for predictive insights into chemical and material design.
