The development of surfaces that have switchable properties, also known as smart surfaces,
have been actively pursued in the past few years. The recent surge of interest in these …

Sensitive, specific, and fast analysis of nucleic acids (NAs) is strongly needed in medicine,
environmental science, biodefence, and agriculture for the study of bacterial contamination …

The reliable discrimination of mutations, single nucleotide polymorphisms (SNPs), and other
differences in genomic sequence is an essential part of DNA diagnostics and forensics. It is …

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 …

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 …

A label-free, surface-enhanced Raman spectroscopy-based assay for detecting DNA
hybridization at an electrode surface and for distinguishing between mutations in DNA is …

The dynamics of electron transport within molecular layers of 3′-ferrocenylated 20-mer
oligonucleotide, 5′-thiol end-grafted onto gold electrode surfaces via a six-carbon (C6) …

The nanoscale arrangement of the DNA probe molecules on sensor surfaces has a
profound impact on molecular recognition and signaling reactions on DNA biosensors and …

The ability to reversibly modulate macroscopic surface properties is an important
requirement for numerous biomedical applications, such as cell culture, tissue engineering …
