Article
Engrailed 2 (EN2) is a homeodomain-containing transcription factor expressed in prostate cancer (PCa) cell lines and is secreted into the urines. It is nowadays considered as a promising non-invasive biomarker for PCa early diagnosis. Herein, we report the design of an electrochemical immunosensor for EN2 detection. The biosensor fabrication involv...

This review critically summarizes the knowledge of imprinted polymer-based electrochemical sensors for the detection of pesticides, metal ions and waterborne pathogenic bacteria, focusing on the last five years. MIP-based electrochemical sensors exhibit low limits of detection (LOD), high selectivity, high sensitivity and low cost. We put the empha...
Preprint
This mini-review critically summarizes the knowledge of imprinted polymer-based electrochemical sensors, for the detection of pesticides, metal ions and waterborne pathogenic bacteria, focusing on the period the last 5 years (citation of 78 papers published in 2017-2021, ie 63% of total citations). MIP-based electrochemical sensors exhibit low limi...

Several studies were devoted to the design of molecularly imprinted polymer (MIP)-based sensors for the detection of a given protein. Here, we bring elements that could contribute to the understanding of the interaction mechanism involved in the recognition of a protein by an imprint. For this purpose, a polydopamine (PDA)-MIP was designed for bovi...
Article
Electrical measurements, dc and ac, show that (AgI)x(HgS)0.5-x/2(As2S3)0.5-x/2 glasses, 0.0 ≤ x ≤ 0.6, exhibit drastic changes in ionic conductivity σi with silver iodide additions. The ionic transport increases by 13 orders of magnitude with increasing silver content from ~0.002 to ~ 23 at.%, and the activation energy decreases from 1.05 to 0.35 e...

Chalcogenide glasses in the pseudo-ternary AgI-HgS-As2S3 system are synthesized and characterized for the first time. The glass-forming region, determined by X-ray diffraction, is relatively large; it covers more than one half of the diagram and is located in the As2S3–rich corner. A particular interest is focused on the two composition glass lines...
Article
Crystalline mercury sulfide exists in two drastically different polymorphic forms in different domains of the P,T-diagram: red chain-like insulator α-HgS, stable below 344 °C, and black tetrahedral narrow-band semiconductor β-HgS, stable at higher temperatures. Using pulsed neutron and high-energy X-ray diffraction, we show that these two mercury b...
Thesis
L'objectif de ce travail a consisté à identifier des polluants émergents dans des eaux usées issues de stations d'épuration ainsi que dans le milieu naturel et à proposer une méthode de remédiation et un suivi de ces polluants. Dans un premier temps, nous avons identifié les polluants organiques contenus dans les échantillons d'eaux usées et issues...
Article
The photocatalytic activity of silver doped mesoporous TiO2 catalysts was evaluated for water treatment. Doped catalysts were prepared by impregnation-reduction with citrate using various Ag loadings (0.5 wt%, 1.5 wt% and 3 wt%) and characterized by X-Ray powder diffraction (XRD), BET and diffuse reflectance UV–vis spectroscopy (DR/UV–vis). Silver...

Pollution of water from a wide range of organic pollutants is a serious environmental problem. Conventional water treatment technologies are not very effective for reducing the concentration of these pollutants to a desirable level. The aim of this work was to evaluate the efficiency of two technologies in reducing the pollutant concentration of tw...

Very little is known about mercury chalcogenide glasses. Using Raman spectroscopy and DFT modelling, we show that the (HgS)x(As2S3)1-x glasses, 0.0 ≤ x ≤ 0.5, form a hybrid Hg-S chain/As-S pyramidal network, highly unusual for metal chalcogenide glasses. This network is evidenced by Hg-S stretching modes at 300 and 370 cm-1 and an As-S spectral env...
