The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Michal Borkovec, Plinio Maroni, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...

Linear Polynuclear Helicates as a Link between Discrete Supramolecular Complexes and Programmed Infinite Polymetallic Chains

Jean-Claude Bünzli, Frédéric Gumy, Michal Borkovec

The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DEMM, in condensed phase to such an extent that stable D3-symmetrical tetranuclear lanthanide-containing triplestranded ...

Nano-patterning of solid substrates by adsorbed dendrimers

Ramon Pericet Camara, Michal Borkovec

Weakly charged solid substrates can be nano-patterned in liquid-like order with large and well-defined spacing by adsorbing poly(amido amine) (PAMAM) dendrimers; highly charged substrates lead to lower spacing due to electrostatic three-body attractions be ...

Interaction forces and molecular adhesion between pre-adsorbed poly(ethylene imine) layers

Ramon Pericet Camara, Michal Borkovec

Interaction forces between pre-adsorbed layers of branched poly(ethylene imine) (PEI) of different molecular mass were studied with the colloidal probe technique, which is based on atomic force microscopy (AFM). During approach, the long-ranged forces betw ...

Probing the validity of the Derjaguin approximation for heterogeneous colloidal particles

Ramon Pericet Camara, Michal Borkovec

The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...

Atomic force microscopy study of the adsorption and electrostatic self-organization of poly(amidoamine) dendrimers on mica

Ramon Pericet Camara, Michal Borkovec

The adsorption behavior of poly(amidoamine) dendrimers to mica surfaces was investigated as a function of ionic strength and pH. The conformation and lateral distribution of the adsorbed dendrimers of generations G8 and G10 were obtained ex situ by tapping ...

Interaction between charged surfaces on the Poisson-Boltzmann level: The constant regulation approximation

Ramon Pericet Camara, Michal Borkovec

Interaction forces between ionizable surfaces across an electrolyte solution on the Poisson-Boltzmann level are discussed within the constant regulation approximation. The chemical response of each surface is expressed in terms of two parameters, namely, t ...
