In this work, impedimetric sensors were developed for the detection of the four WFD heavy metals Pb2+, Cd2+, Hg2+ and Ni2+, by the modification of a gold electrode with four partially biosourced polyphosphine polymers. These polymers were obtained with satisfactory yields by polycondensation of the bis(4-fluorophenyl)(4-methylphenyl)phosphine sulfide and the bis(4-fluorophenyl)(4-methylphenyl)phosphine oxide using isosorbide or bisphenol A. The chemical structures and number-average molecular we...

Heart failure (HF) is a cardiovascular disease affecting about 26 million people worldwide costing about $100 billons per year. HF activates several compensatory mechanisms and neurohormonal systems, so we hypothesized that the concomitant monitoring of a panel of potential biomarkers related to such conditions might help predicting HF evolution. Saliva analysis by point-of-care devices is expected to become an innovative and powerful monitoring approach since the chemical composition of saliva ...

Superparamagnetic nanoparticles are attracting significant attention. Therefore, being explored in microsystems for a wide range of applications. Typical examples include Lab-on-a-chip and microfluidics for synthesis, detection, separation, and transportation of different bioanalytes such as biomolecules, cells, and viruses to develop portable, sensitive, and cost-effective bio-sensing systems. Particularly, microfluidic systems incorporated with magnetic nanoparticles and, in combination with m...

In this work, we report the development of a highly sensitive biosensor for sulfapyridine detection based on an integrated bio micro-electromechanical system (Bio-MEMS) containing four gold working electrodes (WEs), a platinum counter electrode (CE), and a reference electrode (RE). Firstly, the cleaned WEs were modified with 4-aminophenylacetic acid (CMA). Then, (5-[4-(amino)phenylsulfonamide]-5-oxopentanoic acid (SA2BSA) was immobilized onto the transducers surface by carbodiimide chemistry. Th...

Abstract The toxicological and environmental damage caused by glyphosate [N-(phosphonomethyl) glycine] (GLY) has been well documented, however, limited efforts have been made to detect it in the environment. In response to that, we report the development of an extremely sensitive electrochemical sensor for GLY detection in water. This novel concept of glyphosate sensor is based on molecularly imprinted polymer (MIPs) made of chitosan (CS) biopolymer electrochemically deposited onto a gold microe...

Abstract The continuous exchange of chemicals with blood and the non-invasive collection make saliva an interesting specimen for clinical applications, from the detection of biomarkers to the new –omic sciences in medicine. However, saliva sampling is challenging because the suitability of the collection method for the analyte of interest is either poorly investigated or, more often, not mentioned at all in most publications. This review reports a critical evaluation of the most common procedure...
