Adsorption of poly(N-isopropylacrylamide) on glass substrata.
Description :
The adsorption of poly(N-isopropylacrylamide) (PNIPAAM), a well known thermosensitive polymer, on glass was investigated by X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). The polymer was dissolved in water at low (0.02 g/L) and high (2 g/L) concentration and the tested tem...

Nanoscale chemical patterns fabricated by using colloidal lithography and self-assembled monolayers.
Description :
A method for preparing surfaces with well-defined nanoscale chemical patterns is described. The fabrication strategy involves creating nanoscale Au pits surrounded by a TiO2 matrix, or vice versa, using colloidal lithography, followed by selective functionalization of the Au areas by CH3-terminated ...

Description :
We used atomic force microscopy (AFM) to explore the antigen binding forces of individual Fv fragments of antilysozyme antibodies (Fv). To detect single molecular recognition events, genetically engineered histidine-tagged Fv fragments were coupled onto AFM tips modified with mixed self-assembled mo...

Description :
We compare two routes for creating protein adsorption-resistant self-assembled monolayers (SAMs) by chemical modification of silicon surfaces with poly(ethylene oxide) (PEO) oligomeric derivatives. The first route involves the assembly of 2-methyl[(polyethyleneoxy)propyl]trichlorosilane (Cl3SiMPEO) ...

Probing molecular recognition sites on biosurfaces using AFM.
Description :
Knowledge of the molecular forces that drive receptor-ligand interactions is a key to gain a detailed understanding of cell adhesion events and to develop novel applications in biomaterials science. Until recently, there was no tool available for analyzing and mapping these forces on complex biosurf...

In-situ monitoring of the dielectric and electrostrictive properties of anodised thin films for biochip applications.
Description :
Further improving the performance of capacitance-based DNA microsensors will depend on the ability to synthesize simply, at a low cost, thin films of high dielectric permittivity with a well-controlled growth morphology. Anodisation of the valve metals Ti, Zr and Ta is a promising route for preparin...

Surface properties of the conidiospores of Phanerochaete chrysosporium and their relevance to pellet formation.
Description :
The conidiospores of the white rot basidiomycete Phanerochaete chrysosporium tend to aggregate during swelling and germination in agitated liquid medium; as time passes, the initial aggregates tend to associate together and to capture conidiospores that remain isolated. The surface chemical composit...

Synthesis and evaluation of RGD peptidomimetics aimed at surface bioderivatization of polymer substrates.
Description :
Several RGD peptidomimetics have been prepared, in a convergent way, from the common ortho-aminotyrosine template (O-substituted with an anchorage-arm or a methyl group, and alpha N-substituted with a fluorine tag for XPS analysis), and various omega-aminoacid derivatives. The most flexible compound...

Description :
We used real-time atomic force microscopy (AFM) to visualize the interactions between supported lipid membranes and well-defined surfactin analogs, with the aim to understand the influence of geometry, charge and hydrophobicity. AFM images of mixed dioleoylphosphatidylcholine/dipalmitoylphosphatidyl...

In Vivo Imaging of S-Layer Nanoarrays on Corynebacterium glutamicum.
Description :
Crystalline bacterial cell surface layers (S-layers) are monomolecular arrays of (glyco)proteins that have recently produced a wealth of new opportunities in nanotechnology. Whereas the in vitro imaging of isolated S-layers is well established, their direct imaging on live cells remains very challen...
