 Nanolane is proud to announce the launch of its new equipment SARFUS 3D-IMM dedicated to the topographic characterization of nanometric samples in water (know more). We invite you to discover below this innovation through the study of a multilayer polyelectrolytes system observed in aqueous medium.
Other images and an application note are available on the site: http://www.nano-lane.com/polyelectrolytes.php. Also feel free to visit new pages and functionalities on our website and do not hesitate to contact us for more details. (PAH/PSS) Polyelectrolytes Multilayers (10nm of thickness)
MEASURE IN IMMERSION Collaboration: M.Lefort, F.Boulmedais, P.Schaaf, ICS, Strasbourg, France Sarfus Benefits: Real-time image of the sample allowing us checking layers homogeneity more simply and quickly than any other technique is able to do. Possibility to study the swelling behavior of layers by doing measurements in dry and in solution of salt. Generally, a better understanding of the role of many parameters in polyelectrolytes film buildup.  (PAH/PSS) polyelectrolytes multilayers obtained by successive spraying on an Immersion Surf. Layers are observed in real-time in salt solution. Above, is represented the border between the (PAH/PSS)4 layer and (PAH/PSS)7 layer which respectively measure 21.4 nm and 31.6 nm in salt solution. Measurements have been done with SARFUS 3D-IMM. |
