Caros estudantes e docentes,
O próximo seminário do grupo de matéria condensada ocorrerá com a apresentação do Prof. Rodrigo Amorim (UFF-Volta-Redonda). O título e abstract seguem abaixo.
Tarik em nome da comissão organizadora.
Título: Solid-state nanopore for biological sensing
Solid-state nanopores have opened up a new, less expensive path for fast biomolecules sequencing, where the goal is using two-dimensional materials to achieve a single molecule resolution. We shall demonstrate two distinct sensing mechanisms using graphyne and line defect graphene. The first is detecting mutations in amino acids by use of ionic conductivity. Classical molecular dynamics is used for this purpose. The second part of the talk, we will turn to the second mechanism, that is based on electronic conductance to distinguished between each nucleobase. We combined the QM/MM approach with non-equilibrium Green’s functions and density function theory for that.
