A high-throughput supramolecular solvent method for benzophenone quantification in juice packs via liquid chromatography-mass spectrometry
(Elsevier, 2024)Benzophenones (BPs) are among the most frequently detected photoinitiators in liquid packaged food, mainly using liquid chromatography tandem mass spectrometry (LC-MS/MS). However, sample treatments in these methods are ... -
A Novel Brominated Triazine-based Flame Retardant (TTBP-TAZ) in Plastic Consumer Products and Indoor Dust
(ACS, 2014)The presence of a novel brominated flame retardant named 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) is reported for the first time in plastic parts of consumer products and indoor dust samples. TTBP-TAZ ... -
A novel silver-quantum dots "sponge" nanocomposite as sers-active substrate
(Universidad de Córdoba, 2011) -
A paper-based polystyrene/nylon Janus platform for the microextraction of UV filters in water samples as proof-of-concept
(Springer, 2021)A new mix-mode cellulose-based sorptive phase is described that combines two different polymeric domains (i.e., nylon and polystyrene), thus providing simultaneous hydrophilic and hydrophobic features as a result. By analogy ... -
Advanced polymeric solids containing nano- and micro-particles prepared via emulsion-based polymerization approaches. A review
(Elsevier, 2022)This review critically summarizes the latest contributions in the preparation of advanced nano/microparticle-contained polymers from emulsions. The nano- or micro-particles can be dispersed in the phase where the polymerization ... -
An integrated microfluidic-based biosensor using a magnetically controlled MNPs-enzyme microreactor to determine cholesterol in serum with fluorometric detection
(Springer, 2023)This work provides a microfluidic-based biosensor to determine total cholesterol in serum based on integrating the reaction/detection zone of a microfluidic chip of a magnetically retained enzyme microreactor (MREµR) coupled ... -
Analysis of two alternative organophosphorus flame retardants in electronic and plastic consumer products: Resorcinol bis-(diphenylphosphate) (PBDPP) and bisphenol A bis (diphenylphosphate) (BPA-BDPP)
(Elsevier, 2014)Following the phase-out of polybrominated diphenyl ethers (PBDEs), organophosphorus flame retardants (PFRs) are increasingly used as alternative flame retardants in many products. Data on the presence of two alternative ... -

Application of Switchable Hydrophobicity Solvents for Extraction of Emerging Contaminants in Wastewater Samples
(MDPI, 2019)In the present work, the effectiveness of switchable hydrophobicity solvents (SHSs) as extraction solvent (N,N-Dimethylcyclohexylamine (DMCA), N,N-Diethylethanamine (TEA), and N,N-Benzyldimethylamine (DMBA)) for a variety ... -
Astaxanthin from Haematococcus pluvialis Prevents Oxidative Stress on Human Endothelial Cells without Toxicity
(MDPI, 2015)Astaxanthin, a powerful antioxidant, is a good candidate for the prevention of intracellular oxidative stress. The aim of the study was to compare the antioxidant activity of astaxanthin present in two natural extracts ... -
Astaxanthin-Loaded Nanostructured Lipid Carriers for Preservation of Antioxidant Activity
(MDPI, 2018)Astaxanthin is a xanthophyll carotenoid showing efficient scavenging ability and represents an interesting candidate in the development of new therapies for preventing and treating oxidative stress-related pathologies. ... -
Bioinspired composite packed in blunt needles, integrated microextraction and determination of oxycodone and naloxone in saliva by substrate spray mass spectrometry
(Elsevier, 2024)Background: Opioids are effective painkillers used for medical purposes. Their prolonged ingestion can provoke some side effects (including overdose or constipation) that are minimized by using opioid antagonists (e.g., ... -
