Titanium dioxide (TiO2) nanoparticles are ubiquitously used materials in everyday life (eg
paints, household products and plastic goods). However, despite the wide array of common
applications, their pathogenetic role was also suggested under certain conditions (eg …

We report on a comparative study by Transmission Electron Microscopy (HRTEM) and
Scanning Transmission Ion Microscopy (STIM) combined with Rutherford Backscattering
Spectrometry (RBS) and Particle Induced X-Ray Emission (PIXE) on ultra-thin and thin cross …

The permeability of skin to nanoparticles of titanium dioxide (TiO 2) used in sunscreens as a
reflector of the UV wavelengths of sunlight, was examined using nuclear microscopy
techniques. Special attention was given to the permeation characteristics of these …

Toxicity of nanoparticles is a current scientific issue because of the enhanced reactivity of
nanomaterials and their possible easy penetration into the body arising from their small size.
Because inorganic particles are present in sunscreen cosmetic products, attention has been …

Scanning transmission ion microscopy (STIM) is a technique which utilizes the energy loss
of high energy (MeV) ions passing through a sample to provide structural images. In this
paper, we have successfully demonstrated STIM imaging of single cells at the nano-level …

Nuclear microscopy is a technique based on a focused beam of accelerated particles that
has the ability of imaging the morphology of the tissue in vivo and of producing the
correspondent elemental maps, whether in major, minor, or trace concentrations. These …

The spectral response of a Hamamatsu S5821 Si PIN photodiode was investigated with a 2
MeV proton microbeam with high lateral resolution as a function of particle fluence and
applied bias following irradiations with the same particles at the same energy without bias. It …

Ultrafine metal oxides, such as titanium dioxide and zinc oxide are widely used in cosmetic
and health products like sunscreens. These oxides are potent UV filters and the small
particle size makes the product more transparent compared to formulations containing …

The distribution of Fe in skin was assessed to monitor body Fe status in human hereditary
hemochromatosis. The paper reports on data from nine patients with hemochromatosis that
were studied along the therapeutic programme. Systemic evaluation of Fe metabolism was …

Imaging the morphology of the tissue in vivo and producing the correspondent elemental
maps, whether in major, minor, or trace concentrations in real-time can be done using a
focused beam of accelerated particles. This can be accomplished using different ion beam …
