The aim of the present study was the assessment of the sub-chronic effects of silver (AgNPs) and gold nano-particles (AuNPs) of 40 nm primary size either stabilised with citrate (CIT) or coated with polyethylene glycol (PEG) on the freshwater invertebrate Gammarus fossarum. Silver nitrate (AgNO 3) was used as a positive control in order to study th...

Gene expression profiling via RT-qPCR is a robust technique increasingly used in ecotoxicology. Determination and validation of optimal reference genes is a requirement for initiating RT-qPCR experiments. To our best knowledge, this study is the first attempt of identifying a set of reference genes for the freshwater crustacean Gammarus fossarum. S...
Article
The specific and unique properties of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs), make them of high interest for different scientific and industrial applications. Their increasing use will inevitably lead to their release in the environment and aquatic ecosystems where they may represent a threat to aquatic organisms. Being a wides...
Article
Full-text available
The enormous investments in nanotechnology have led to an exponential increase of new manufactured nano-enabled materials whose impact in the aquatic systems is still largely unknown. Ecotoxicity and nanosafety studies mostly resulted in contradictory results and generally failed to clearly identify biological patterns that could be related specifi...
Article
Full-text available
One of the direct causes of biodiversity loss is environmental pollution resulting from the use of chemicals. Different kinds of chemicals, such as persistent organic pollutants and some heavy metals, can be endocrine disruptors, which act at low doses over a long period of time and have a negative effect on the reproductive and thyroid system in v...
Data
Applied voltage and discharge current measured in the AP-DBD operating in continuous mode and fed with a 5 μL min-1 precursor mixture.
Data
UV spectra of DOA in solution in HEMA at 3.3 mg mL-1.
Data
Lissajous figure for the AP-DBD operating in continuous (CW) mode and fed with pure argon (black curve) and a 5 μL min-1 precursor mixture diluted (red curve).
Data
Evolution of the thickness of pp(DOA-HEMA) films deposited at 1:15 ms according to the number of runs.
Data
Dark field microscopy image with the corresponding spectral profile for a blue point (A) and a green point (B) for a pp(layer) deposited at 1:15 ms.
Data
End-groups composition estimated from ESI mass spectrum recorded for a pp(DOA-HEMA) deposited in a 1:400 ms pulsed mode.
Data
UV spectra of pp(DOA-HEM) film deposited in a 1:400 ms pulsed mode on a silicon wafer and dissolved in ethanol (i.e, UV transmission mode) (A) and on stainless steel disks (i.e., UV reflectance mode) (B).

Full-text available
In this work, an atmospheric aerosol assisted pulsed plasma process is reported as an environmentally friendly technique for the preparation of tunable catechol-bearing thin films under solvent and catalyst free conditions. The approach relies on the direct injection of dopamine acrylamide dissolved in 2-hydroxyethylmethacrylate as comonomer into t...
Article
Potential toxic effects of Ag NPs ingested through the food web and depending on the season have not been addressed in marine bivalves. This work aimed to assess differences in protein expression in the digestive gland of female mussels after dietary exposure to Ag NPs in autumn and spring. Mussels were fed daily with microalgae previously exposed...
Thesis
The potential toxicity of nanomaterials is of high societal and scientific interest due to the promise of ground-breaking innovations for many technical applications. However, toxicity can often not be related to the actual size, mass or surface area of the single nanoparticles (NPs) or the NP agglomerates. Therefore, it can be proposed that the to...

Welcome to the final conference of the COST Action ES1205. The most important aim of our Action was to create a pan-European network and, glancing at the book of abstracts – I can say – we were successful. The majority of contributions you will find here were influenced by our activities. The foundations of this Action however, must certainly be th...

This paper highlights the use of Al2O3 and SnO2 films as protecting layers to tailor the optical properties and biocompatibility of ZnO nano-films. ZnO, ZnO/Al2O3 and ZnO/SnO2 nano-films have been deposited inside 3-dimensional (3D) structures such as anodic aluminium oxide (AAO) membranes via a gas phase atomic layer deposition (ALD) process. We s...
