Quantum Simulation of the Silicene and Germanene for Sensing and Sequencing of DNA/RNA Nucleobases

open access: yesBiosensors, 2021
Over the last decade, we have been witnessing the rise of two-dimensional (2D) materials. Several 2D materials with outstanding properties have been theoretically predicted and experimentally synthesized.

A TDDFT Computational Study of Platinum Complexes Bound to Nucleobases [PDF]

open access: yes, 2016
The electronic spectra of a number of platinum (II) complexes bound to single nucleobases have been investigated using Time-Dependent Density Functional Theory (TDDFT). The calculated spectra obtained in this work have been benchmarked against recent gas-

Computation of Oxidation Potentials of Solvated Nucleobases by Static and Dynamic Multilayer Approaches [PDF]

open access: yes, 2022
The determination of the redox properties of nucleobases is of paramount importance to get insight into the charge-transfer processes in which they are involved, as those occurring in DNA-inspired biosensors.

Characterising conical intersections in DNA/RNA nucleobases with multiconfigurational wave functions of varying active space size [PDF]

open access: yes, 2023
We characterise the photochemically relevant conical intersections between the lowest-lying accessible electronic excited states of the different DNA/RNA nucleobases using Cholesky decomposition-based complete active space selfconsistent field (CASSCF ...

Intramolecular and Intermolecular Hole Delocalization Rules the Reducer Character of Isolated Nucleobases and Homogeneous Single-Stranded DNA [PDF]

open access: yes, 2023
The use of DNA strands as nanowires or electrochemical biosensors requires a deep understanding of charge transfer processes along the strand, as well as of the redox properties.

Hammerhead Ribozymes: True Metal or Nucleobase Catalysis? Where Is the Catalytic Power from?

open access: yesMolecules, 2010
The hammerhead ribozyme was first considered as a metalloenzyme despite persistent inconsistencies between structural and functional data. In the last decade, metal ions were confirmed as catalysts in self-splicing ribozymes but displaced by nucleobases ...

Development of a Universal Nucleobase and Modified Nucleobases for Expanding the Genetic Code [PDF]

open access: yesCurrent Protocols in Nucleic Acid Chemistry, 2002
AbstractThis unit presents protocols for the synthesis and characterization of nucleosides with unnatural bases in order to develop bases for the expansion of the genetic alphabet or for nonselective pairing opposite natural bases. Protocols describe the design, synthesis, and characterization of unnatural base pairs involving 1‐β‐D‐2‐deoxyribosyl‐N ...
