The base pair stack of DNA has been demonstrated as a medium for long-range charge
transport chemistry both in solution and at DNA-modified surfaces. This chemistry is …

Guanine is the most easily oxidizable base in DNA under various oxidative conditions (see
section 4), including in the presence of the hydroxyl radical (OH•) and related radicals …

Seventy years after its discovery, the zika virus emerged in Brazil and spread rapidly
throughout the Americas, bringing unusual complications such as microcephaly. The World …

We describe self-assembly of ssDNA brushes that exploits the intrinsic affinity of adenine
nucleotides (dA) for gold surfaces. The grafting density and conformation of these brushes is …

A sensitive ratiometric electrochemical readout was designed with an immunoreaction-
triggered DNA assembly for one-step, fast and flexible assay of protein biomarker. The …

We report on the dynamic control over the orientation of short oligonucleotide strands which
are tethered to gold surfaces in electrolyte solution. By applying alternating electrical bias …

The creation of gold surfaces modified by single-or double-stranded DNA self-assembled
monolayers (SAMs) is shown to produce heterogeneous surface packing densities through …

We report a method to detect label-free oligonucleotide targets. The conformation of surface-
tethered probe nucleic acids is modulated by alternating electric fields, which cause the …

We describe the behavior of 72mer oligonucleotides that are end-tethered to gold surfaces
under the influence of applied electric fields. The DNA extension is measured by …

Understanding the structural reconfiguration of a biomolecular receptor remains a topic of
particular interest to the biosensing community. This is because conformationally changing …
