The links between neuropathies of the peripheral nervous system (PNS), including Charcot-Marie-Tooth1A and hereditary neuropathy with liability to pressure palsies, and impaired biomechanical and structural integrity of PNS nerves remain poorly understood despite the medical urgency. Here, we present a protocol describing simultaneous structural and biomechanical integrity investigations on iso...

using c2h2, 112 and as gases at 550'c, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by dc magnetron sputtering. aystamless steel andfe/cteal, by thermal chemical vapor deposition (tcvd) the surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the cnt's growth is cri...

Yeast nanobiotechnology is a recent field where nanotechniques are used to manipulate and analyse yeast cells and cell constituents at the nanoscale. The aim of this review is to give an overview and discuss nanobiotechnological analysis and manipulation techniques that have been particularly applied to yeast cells. These techniques have mostly been applied to the model yeasts Saccharomyces cer...

Abstract A recently developed atomic force microscope process, the PeakForce quantitative nanomechanical mapping (PF-QNM) mode, allows us to probe over a large spatial region surface topography together with variety of mechanical properties (e.g. apparent modulus, adhesion, viscosity). The resulting set data often exhibits strong coupling between material response and topography. This letter pr...

Probing oriented bacterial cell growth on the nanoscale: A novel open-top micro-channel is developed to facilitate the AFM imaging of physically trapped but freely growing bacteria. The growth curves of individual Escherichia coli cells with nanometer resolution and their kinetic nano-mechanical properties are quantitatively measured.

All atomic force microscope (AFM) images suffer from distortions, which are principally produced by the interaction between the measured sample and the AFM tip. The atomic force microscope (AFM) is a very important instrument for use in nanotechnology and biology since it can be used to measure a wide variety of objects, such as nano-particles and cells, either in air or liquid. However, the im...

Facemasks have been a critical line of defense in the Covid-19 pandemic and used for decades to reduce inhalation sub-micron aerosols, including bacteria, viruses nano-materials. These facemasks leverage electrostatic charge properties non-woven electret fibre mats remove aerosols. However, topographical these not well characterized at nano-scale. In this study, we use atomic force microscopy (...
