A Molecularly Imprinted Polypyrrole/GO@Fe3O4 Nanocomposite Modified Impedimetric Sensor for the Routine Monitoring of Lysozyme
Montoro-Leal, Pablo; Morales Frías, Isaac Aarón; Vereda-Alonso, Elisa Isabel
; Errachid, Abdelhamid; Jaffrezic-Renault, Nicole (IOAP-MPDI, 2022-09-05)
Lysozyme (LYS) applications encompass anti-bacterial activity, analgesic, and anti-inflammatory effects. In this work, a porous framework that was based on the polymerization of pyrrole (PPy) in the presence of multi-functional ... -
A systematic evaluation on the impact of sample-related and environmental factors in the analytical performance of acoustic emission from laser-induced plasmas
Bosáková, Markéta; Purohit, Pablo; Álvarez-Llamas, César; Moros-Portolés, Javier; Novotný, Karel; Laserna-Vázquez, José Javier[et al.] (Elsevier, 2022-09-08)
Acoustics recordings from laser-induced plasmas are becoming increasingly regarded as a complementary source of information from the inspected sample. The propagation of these waves is susceptible to be modified by the ... -
LIBS-Acoustic Mid-Level Fusion Scheme for Mineral Differentiation under Terrestrial and Martian Atmospheric Conditions
Álvarez-Llamas, César; Purohit, Pablo; Laserna-Vázquez, José Javier (American Chemical Society, 2022-01-12)
The shockwave produced alongside the plasma during a laser-induced breakdown spectroscopy event can be recorded as an acoustic pressure wave to obtain information related to the physical traits of the inspected sample. In ... -
Magnetic graphene molecularly imprinted polypyrrole polymer (MGO@MIPy) for electrochemical sensing of malondialdehyde in serum samples
Montoro-Leal, Pablo; Zougagh, Mohammed; Sánchez-Ruiz, Antonio; Rios, Angel; Vereda-Alonso, Elisa Isabel (Elsevier, 2022-03-12)
A modified screen-printed carbon electrode (SPCE) has been designed and fabricated for the determination of malondialdehyde (MDA), an important biomarker of oxidative stress. Magnetic graphene oxide (MGO) was synthesized ... -
Magnetic graphene oxide as a valuable material for the speciation of trace elements
Morales-Benítez, Irene; Montoro Leal, Pablo; García Mesa, Juan Carlos; Verdeja-Galán, J; Vereda-Alonso, Elisa Isabel (Elsevier, 2022-12)
Magnetic solid phase extraction (MSPE) has been explored for the application in preconcentration processes to achieve highly sensible analytical methods. Attending to the different magnetic adsorbent materials used in this ... -

A novel sorbent material employing magnetic nanoparticles (MNPs) coupled to graphene oxide (GO) functionalized with 4-aminobenzenesulfonic acid (M@GO-ABS) has been synthesized and applied to develop an inexpensive and ... -
Semiautomatic method for the ultra-trace arsenic speciation in environmental and biological samples via magnetic solid phase extraction prior to HPLC-ICP-MS determination
Montoro-Leal, Pablo; García-Mesa, Juan Carlos; Morales-Benítez, Irene; García-de-Torres, Amparo; Vereda-Alonso, Elisa Isabel (Elsevier B.V., 2021)
A novel magnetic functionalized material based on graphene oxide and magnetic nanoparticles (MGO) was used to develop a magnetic solid phase extraction method (MSPE) to enrich both, inorganic and organic arsenic species ... -
Sensitive determination of mercury by magnetic dispersive solid-phase extraction combined with flow-injection-cold vapour-graphite furnace atomic absorption spectrometry
García-Mesa, Juan Carlos; Montoro-Leal, Pablo; Maireles-Rivas, Silvia; López-Guerrero, María del Mar; Vereda-Alonso, Elisa Isabel (Royal Society of Chemistry, 2021-03-31)
Mercury is a non-essential trace element that is toxic to humans due to the bioaccumulation effect. In this work, a ferrofluid based on Fe3O4@graphene oxide nanospheres together with an ionic liquid was used to develop a ... -
The crucial role of molecular emissions on LIBS differentiation of organic compounds of interest in astrobiology under a Mars simulated atmosphere
Delgado-Pérez, Tomás; Fortes-Roman, Francisco Javier; Cabalín-Robles, Luisa María; Laserna-Vázquez, José Javier (Elsevier, 2022-12-04)
In this work, the influence of Martian atmosphere on the recombination mechanisms in laser-induced plasmas of organic compounds of interest in astrobiology has been closely examined. The proposed LIBS methodology reveals ... -
