Sulphate sensing in self-assembled monolayers by surface infrared and Raman spectroscopy techniques

Autor: Robert Pomorski, Michał J. Chmielewski, Barbara Palys, Piotr Piotrowski, Jolanta Bukowska

Publikováno v: Sensors and Actuators B: Chemical. 283:172-181

In this paper we demonstrate the applicability of surface vibrational spectroscopy techniques in sensing sulphate anions, using self-assembled monolayers of hydrogen bonding receptors. Three uncharged, diamidocarbazole receptors were synthesised and

Influence of amine and thiol modifications at the 3′ ends of single stranded DNA molecules on their adsorption on gold surface and the efficiency of their hybridization

Autor: Aleksandra Jaworska, Andrzej Kudelski, Tomasz Wilanowski, Slawomir Sek, Barbara Palys, Anna Jabłońska

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 203:31-39

Adsorption of molecules of DNA (deoxyribonucleic acid) or modified DNA on gold surfaces is often the first step in construction of many various biosensors, including biosensors for detection of DNA with a particular sequence. In this work we study th
