Integrated microfluidic systems for fluorescence monitoring rapid kinetic reactions in bioanalysis
(Springer, 2023)A stopped-flow microfluidic fluorimetric biosensor to monitor alkaline phosphatase (ALP) activity and evaluate the potential inhibitors has been developed, integrating a magnetically retained enzyme microreactor (MREμR) ... -
Integrating in-vial thin film microextraction using polysiloxane-based adhesive tapes with low-temperature plasma ionization mass spectrometry: A solvent-free approach for determining cocaine and methamphetamine in saliva samples
(Royal Society of Chemistry, 2025)The direct combination of sample preparation and mass spectrometry (MS) arose as an alternative to classical chromatographic methods, reducing solvent consumption while increasing the analysis throughput. In this combination, ... -
Intercomparación en análisis cuantitativo por espectrómetro de dispersión de energía de rayos X (EDE)
(2013-11-28)Las intercomparaciones son una base sólida para consolidar un sistema de calidad y un sustento importante en las aspiraciones para obtener la certificación de un laboratorio. Con éstas, el desempeño analítico de cada ... -
Ionic-liquid-based microextraction method for the determination of silver nanoparticles in consumer products
(Springer, 2019)A simple method to determine hazardous silver nanoparticles (AgNPs) based on ionic liquid (IL) dispersive liquid–liquid microextraction and back-extraction is described. This approach involves AgNP stabilization using a ... -
Lab in a bottle, open-source technologies for the design of affordable environmental samplers integrating on-site extraction
(Elsevier, 2023)Access to clean water, a Sustainable Development Goal, can only be accomplished worldwide using affordable technologies. In the analytical chemistry realm, developing cheap devices capable of on-site extraction results in ... -
Limited uptake, translocation and enhanced metabolic degradation contribute to glyphosate tolerance in Mucuna pruriens var. utilis plants
(Elsevier, 2012)Velvet bean (Mucuna pruriens, Fabaceae) plants exhibits an innate, very high resistance (i.e., tolerance) to glyphosate similar to that of plants which have acquired resistance to this herbicide as a trait. We analyzed the ... -
Liquid chromatography-diode array detection to study the metabolism of glufosinate in Triticum aestivum T-590 and influence of the genetic modification on its resistance
(2013)The resistance to glufosinate of two lines—genetically modified (GM) and unmodified (T-590 and T-549, respectively)—of Triticum aestivum has been studied. In the GM line, the bar gene was introduced to increase the resistance ... -
