Modified distribution in the polyphenolic profile of rosemary leaves induced by plant inoculation with an arbuscular mycorrhizal fungus
BACKGROUND: Rosemary forms an arbuscular mycorrhizal (AM) symbiosis with a group of soilborne fungi belonging to the phylum Glomeromycota, which can modify the plant metabolome responsible for the antioxidant capacity and ...
Evaluation of a virus concentration method based on ultrafiltration and wet foam elution for studying viruses from large-volume water samples
Assessing the presence of viruses in large-volume samples involves cumbersome methods that require specialized training and laboratory equipment. In this study, a large volume concentration (LVC) method, based on dead-end ...
Enhanced terahertz sensitivity for glucose detection with a hydrogel platform embedded with Au nanoparticles
We presented a strategy for enhancing the sensitivity of terahertz glucose sensing with a hydrogel platform pre-embedded with Au nanoparticles. Physiological-level glucose solutions ranging from 0 to 0.8 mg/mL were measured ...
Considerations on the use of spectroelectrochemistry in reflection mode for quantitative analysis: Study of the Fe(III)/Fe(II) - orthophenanthroline system
Theoretical and experimental considerations are made about possible analytical applications of spectroelectrochemistry (SEC) in reflection mode using screen-printed electrodes. The system Fe(III)/Fe(II) - orthophenanthroline ...
Multivariate standard addition for the analysis of overlapping voltammetric signals in the presence of matrix effects: Application to the simultaneous determination of hydroquinone and catechol
A multivariate version of the classical univariate standard addition method is tested as a proof of concept for the voltammetric analysis of complex samples generating overlapped signals in the presence of significant ...
Evaluation of synthesis conditions for plastic scintillation foils used to measure alpha- and beta-emitting radionuclides
Plastic scintillation foils of polystyrene and polycarbonate with a thickness between 45 and 200 μm, have been produced using the solvent evaporation method. PSfoils presented a reproducible thickness (10-20%). PSfoils ...
Arsenosugar extracted from algae: Isolation by anionic exchange solid-phase extraction
Obtaining reliable speciation data for evaluating dietary exposure, and increasing understanding of arsenic biochemistry in algae, are hindered by the availability of suitable standards of arsenosugars, the major species ...
