Large colloidal probes for atomic force microscopy: fabrication and calibration issues
M. Chighizola, L. Puricelli, L. Bellon +1
Atomic force microscopy (AFM) is a powerful tool to investigate interaction forces at the micro and nanoscale. Cantilever stiffness, dimensions and geometry of the tip can be chose…
Growth mechanism of cluster-assembled surfaces: from sub-monolayer to thin film regime
Francesca Borghi, Alessandro Podestà, Claudio Piazzoni +1
Nanostructured films obtained by the assembling of preformed atomic clusters are of strategic importance for a wide variety of applications. The deposition of clusters produced in…
Nanomanufacturing of titania interfaces with controlled structural and functional properties by supersonic cluster beam deposition
Alessandro Podestà, Francesca Borghi, Marco Indrieri +3
Great emphasis is placed on the development of integrated approaches for the synthesis and the characterization of ad hoc nanostructured platforms, to be used as templates with con…
Nanomechanical and topographical imaging of living cells by Atomic Force Microscopy with colloidal probes
Luca Puricelli, Massimiliano Galluzzi, Carsten Schulte +2
Atomic Force Microscopy (AFM) has a great potential as a tool to characterize mechanical and morphological properties of living cells; these properties have been shown to correlate…
Nanoscale roughness and morphology affect the IsoElectric Point of titania surfaces
F. Borghi, V. Vyas, A. Podestà +1
We report on the systematic investigation of the role of surface nanoscale roughness and morphology on the charging behaviour of nanostructured titania (TiO2) surfaces in aqueous s…
Nano-indentation of a room-temperature ionic liquid film on silica: a computational experiment
P. Ballone, M. G. Del Pópolo, S. Bovio +3
We investigate the structure of the [bmim][Tf2N]/silica interface by simulating the indentation of a thin (4 nm) [bmim][Tf2N] film by a hard nanometric tip. The ionic liquid/silica…
Early events in insulin fibrillization studied by time-lapse atomic force microscopy
A. Podesta', G. Tiana, P. Milani +1
The importance of understanding the mechanism of protein aggregation into insoluble amyloid fibrils relies not only on its medical consequences, but also on its more basic properti…
Quantitative Nanofriction Characterization of Corrugated Surfaces by Atomic Force Microscopy
A. Podesta', G. Fantoni, P. Milani
Atomic Force Microscopy (AFM) is a suitable tool to perform tribological characterization of materials down to the nanometer scale. An important aspect in nanofriction measurements…
Nanotribological characterization of industrial Polytetrafluorethylene-based coatings by atomic force microscopy
A. Podesta', G. Fantoni, P. Milani +2
We present the result of a systematic study of the tribological properties of industrial Polytetrafluorethylene (PTFE)-based coatings carried out with an atomic force microscope. A…
Fractal analysis of Sampled Profiles: Systematic Study
C. Castelnovo, A. Podestà, P. Piseri +1
A quantitative evaluation of the influence of sampling on the numerical fractal analysis of experimental profiles is of critical importance. Although this aspect has been widely re…
