Microscopy methods for biofilm imaging: focus on SEM and VP-SEM pros and cons
Several imaging methodologies have been used in biofilm studies, contributing to deep- ening the knowledge on their structure.

Today, biomaterial research on biomimetic mineralization strategies represents a new challenge in the prevention and cure of enamel mineral loss on delicate deciduous teeth. Distinctive assumptions about the origin, the growth, and the functionalization on the biomimetic materials have been recently proposed by scientific research studies in evaluating the different clinical aspects of treating the deciduous tooth. Therefore, appropriate morpho-chemical observations on delivering specific biomaterials to enamel teeth is the most important factor for controlling biomineralization processes.
Background: Scanning electron microscopy (SEM) study of the human incus bone is scanty whilst, to our knowledge, no information regarding human incudo-malleolar joint articular-cartilage morphology has previously been provided.
Aims/objectives: Our aim was to shed some light on this morphological issue and to propose some theoretical perspectives on its functional role.
Material and methods: The human incudo-malleolar joint was documented with field emission SEM on samples recovered during ear surgery procedures after patients’ informed consent.
Bacterial biofilm plays a pivotal role in chronic Staphylococcus aureus (S. aureus) infection and
A porous graphene based PVDF aerogel is produced through a cost-effective procedure, for possible application as sweat sensor. The aerogel samples were characterized in terms of porosity, density, morphological and electrical properties through high-resolution scanning electron microscopy (HR-SEM) and time-monitoring of the sample dc electrical resistance.
Bio-deterioration poses a serious risk in the preservation of ancient parchments. The deteriorating effects of microorganism can affect the surface layers of a membrane sheet causing the total loss of the written text and/or the decorative apparatus of which it is the vehicle. In this work the use of the X-ray radiation performed by an experimental setup, designed at ENEA Frascati, is proposed to inhibit the microbial growth.
Phoenician expansion spread all over the Mediterranean coast and came together with the foundation of new
colonies. Red Slip Ware, a ceramic class characterized by a shiny deep red surface, seems to be a good marker to
identify and to date the early Phoenician presence on the territory. Indeed, Red Slip Ware is found in every Phoenician
site, from the motherland to the colonies. Representative fragments of Red Slip Ware from the Phoenician-Punic site of
The heat capacity of di-, tri- and tetramethylammonium lead iodide perovskites of general formula (CH3)xNH4–xPbI3 (where 2≤x≤4) has been determined by differential scanning calorimetry (DSC) in the temperature range 289–473 K using the step-scan mode. Standard molar values C0p(298 K) of di-, tri- and tetramethylammonium lead iodide perovskites were found to be: (285.2, 318.8 and 363.4) J K–1 mol–1, respectively. Heat capacity data have been used to evaluate the thermodynamic functions of the three (CH3)xNH4–xPbI3 perovskites (entropy and enthalpy increment).
Amine oxidases, which contribute to the regulation of polyamine levels, catalyze the oxidative deamination of polyamines to generate H2O2 and aldehyde(s). In this study, and at least to the best of our knowledge, maize polyamine oxidase (ZmPAO) was used for the first time with the aim of identifying a novel strategy for cancer therapy. The cytotoxicity and the mechanisms of cell death induced by the enzymatic oxidation products of polyamine generated by ZmPAO were investigated.
