Characterization of a modified gold platform for the development of a label-free anti-thrombin aptasensor
(Elsevier Science, 2012-09)
This work reports the characterization of a modified gold surface as a platform for the development of a label free aptasensor for thrombin detection. The biorecognition platform was obtained by the self-assembly of ...
Cationic and anionic polyelectrolyte complexes of xylan and chitosan: Interaction with lignocellulosic surfaces
(Elsevier, 2016-10)
Cationic (CatPECs) and anionic (AnPECs) polyelectrolyte complexes from xylan and chitosan were formed, characterized and adsorbed onto unbleached fibers for improving the papermaking properties. They were prepared at a ...
