Novel polymeric nanoparticles as nanofertilisers for alkaline iron‐deficient co...

Background and aims Iron deficiency chlorosis (IDC) is a nutritional disorder impacting plants and is prevalent in calcareous alkaline soils, correspond- ing to 30% of the world’s arable land. IDC compro- mises iron uptake in crops such as soybean (Glycine max). To improve the effect of iron fertilisers, we sought to develop a nanotechnology-based interven- tion using polymeric nanoparticles (NPs) loaded with F...

Sequential injection lab-on-valve with bead injection for iron speciation in wa...

Use of a rhodamine-based chelator in a microfluidic paper-based analytical devi...

This work describes the development of a microfluidic paper-based analytical device (μPAD) for the determination of copper in fresh and marine waters. A functionalized rhodamine-based chelator was synthesized and used as a chromogenic reagent, forming a highly intense pink complex with the analyte. The aim was to create a paper device that offers optimal performance and provides in-situ, rapid and cost-effectiv...

Microfluidic paper-based device incorporated with silica nanoparticles for iodi...

Iodine is an essential micronutrient for humans due to its fundamental role in the biosynthesis of thyroid hormones. As a key parameter to assess health conditions, iodine intake needs to be monitored to ascertain and prevent iodine deficiency. Iodine is available from various food sources (such as seaweed, fish, and seafood, among others) and dietary supplements (multivitamins or mineral supplements). In this ...

New iron nanofertilizers to amend chlorosis in soybean plants

Iron determination in natural waters using a synthesised 3-hydroxy-4-pyridione ...

This work describes the development of an iron sensor based on a microfluidic paper-based technique, to attain iron quantification in natural waters. A new water-soluble naphthalene-3-hydroxy-4-pyridione ligand was used as a colour reagent, as it formed an orange complex with iron. As a newly described ligand, several chemical and physical parameters, namely, the sample and reagent volumes and reagent concentra...

Iron nanofertilizers for the development of sustainable soybean crops

Advanced nanofertilizers for iron uptake in calcareous alkaline soils

Gene expression analysis of soybean plants treated with iron-based nanofertilizers

Non-transferrin-bound iron determination in blood serum using microsequential i...

Non-transferrin-bound iron (NTBI) is a group of circulating toxic iron forms, which occur in iron overload or health conditions with dysregulation of iron metabolism. NTBI is responsible for increased oxidative stress and tissue iron loading. Despite its relevance as a biochemical marker in several diseases, a standardized assay is still lacking. Several methods were developed to quantify NTBI, but results show...
