Removal and sensing of emerging pollutants released from (micro)plastic degrada...
Oliveira, Thiago M.B.F.; Ribeiro, Francisco W.P.; Morais, Simone; de Lima-Neto, Pedro; Correia, Adriana N.The negative impacts of microplastics on the environment and human health cannot be unnoticed. Several classes of emerging pollutants with endocrine-disrupting properties such as bisphenol A and its analogs, phthalates, among others, have been reported to migrate out of plastics entering the aquatic environment. Thus, this review aims to draw attention to the significant potential of the boron-doped diamond ele...
(Bio)Sensing Strategies Based on Ionic Liquid-Functionalized Carbon Nanocomposi...
Torrinha, Álvaro; Oliveira, Thiago M. B. F.; Ribeiro, Francisco W. P.; de Lima-Neto, Pedro; Correia, Adriana N.; Morais, SimoneThe interaction of carbon-based nanomaterials and ionic liquids (ILs) has been thoroughly exploited for diverse electroanalytical solutions since the first report in 2003. This combination, either through covalent or non-covalent functionalization, takes advantage of the unique characteristics inherent to each material, resulting in synergistic effects that are conferred to the electrochemical (bio)sensing syst...
Application of Nanostructured Carbon-Based Electrochemical (Bio)Sensors for Scr...
Torrinha, Álvaro; Oliveira, Thiago M. B. F.; Ribeiro, Francisco W.P.; Correia, Adriana N.; Lima-Neto, Pedro; Morais, SimonePharmaceuticals, as a contaminant of emergent concern, are being released uncontrollably into the environment potentially causing hazardous effects to aquatic ecosystems and consequently to human health. In the absence of well-established monitoring programs, one can only imagine the full extent of this problem and so there is an urgent need for the development of extremely sensitive, portable, and low-cost dev...
Electroanalysis of Pharmaceuticals on Boron‐Doped Diamond Electrodes: A Review
Sousa, Camila P.; Ribeiro, Francisco W. P.; Oliveira, Thiago M. B. F.; Salazar‐Banda, Giancarlo R.; Lima‐Neto, Pedro de; Morais, SimoneBoron‐doped diamond (BDD) electrodes possess outstanding physical, chemical, and electronic properties and have been successfully, yet in a limited way, explored in the electroanalysis of substances with therapeutic action (analgesics, antipyretics, antibiotics, anti‐inflammatories, antihypertensives, antidepressants, vitamins, and others) in diverse milieus (pharmaceutical formulations, urine, serum, whole blo...
Trends and frontiers in graphene-based (bio)sensors for pesticides electroanalysis
Sousa, Camila P.; Ribeiro, Francisco W.P.; Oliveira, Thiago M.B.F.; Correia, Adriana N.; de Lima-Neto, Pedro; Morais, SimoneUndoubtedly, carbonaceous (nano)materials are the most widely used feedstock to obtain improvements in electrochemical devices, but graphene has attracted strong scientific and technological interest due to its exceptional physicochemical properties. Graphene-sheets functionalization, integration with metallic nanoparticles, organic and inorganic molecules and/or groups, synthesis method, and chemical or therma...

Experimental and computational studies of the interactions between carbon nanot...
Salvador, Michele A.; Sousa, Camila P.; Maciel, Cleiton D.; Gomes, Rayane N.; Morais, Simone; Lima-Neto, Pedro de; Coutinho-Neto, Maurício D.The interactions between multi-walled carbon nanotubes and different amounts of an ionic liquid (IL), as well asthe interactions between this system (used as electrochemical sensor) and acetaminophen (ACOP), were in-vestigated through both experimental and theoretical methodologies. Experiments indicated that there is anoptimal concentration of ionic liquid for ACOP detection. A host of techniques and model sys...
Dispersion of multi-walled carbon nanotubes in [BMIM]PF 6 for electrochemical s...
Gomes, Rayane N.; Sousa, Camila P.; Casciano, Paulo N.S.; Ribeiro, Francisco Wirley P.; Morais, Simone; Lima-Neto, Pedro de; Correia, Adriana N.The influence of functionalized multi-walled carbon nanotubes (fMWCNT) in the presence of 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6) in different ratios was investigated on the acetaminophen (ACOP) electrochemical determination. The electrochemical behavior of the ACOP exhibited a pair of well-defined redox peaks, suggesting that the reversibility of ACOP was significantly improved in compariso...
Chitosan-magnetite nanocomposite as a sensing platform to bendiocarb determination
Oliveira, Raissa C. de; Sousa, Camila P.; Freire, Tiago M.; Freire, Rafael M.; Denardin, Juliano C.; Fechine, Pierre B. A.; Becker, HelenaA novel platform for carbamate-based pesticide quantification using a chitosan/magnetic iron oxide (Chit-Fe3O4) nanocomposite as a glassy carbon electrode (GCE) modifier is shown for an analytical methodology for determination of bendiocarb (BND). The BND oxidation signal using GCE/Chit-Fe3O4 compared with bare GCE was catalyzed, showing a 37.5% of current increase with the peak potential towards less positive ...
Electroanalysis of Imidacloprid Insecticide in River Waters Using Functionalize...
Paiva, Wyslley Douglas A.; Oliveira, Thiago Mielle B. F.; Sousa, Camila P.; Neto, Pedro de Lima; Correia, Adriana N.; Morais, Simone; Silva, Djalma R.In this work, a functionalized multi-walled carbon nanotubes modified glassy carbon electrode (GCE/MWCNT-f) was optimized for the direct determination of imidacloprid (IMC) insecticide in river water. The functionalized material was characterized by infrared spectroscopy with Fourier transform (FTIR) and the modified electrode by scanning electron microscopy (SEM) and cyclic voltammetry (CV). Results revealed t...
