We have developed a novel approach for the colorimetric and fluorescent detection of protamines based on an anionic polythiophene derivative. This probe has high sensitivity and selectivity toward protamines with a linear detectable range from 0.1 to 30 μg mL(-1), and can be used for protamine detection in serum samples.

In this paper, the structural and electronic properties of polythiophene and polyprrrole-based systems have been investigated using first-principles calculations both in periodic and oligomer forms. Of particular interest is the band gap modulation through substitutions and bilayer formation. Specifically, S has been substituted by Se and Te in polythiophene, leading to polyseleophene and polyt...

The electronic and structural properties of oligo- and polythiophenes that can be used as building blocks for molecular electronic devices have been studied by using periodic density functional theory calculations. We have in particular focused on the effect of substituents on the electronic structure of thiophenes. Whereas singly bonded substituents, such as methyl, amino or nitro groups, chan...
