The mineral content, vitamin C, and chlorogenic acid were determined in 44 genotypes of Andean potatoes reintroduced in the Quebrada de Humahuaca, Jujuy, Argentina. This initiative aims to promote biodiversity and support local producers by determining the nutritional and functional properties of these genotypes. The genotypes from a collection in the Germplasm Bank of INTA Balcarce, were planted in sandy clay loam soils and harvested manually.

The development of a sensitive and selective silver nanoparticle assay for the quantitation of vitamin C (SNaP-C), as ascorbic acid (AA) and total ascorbic acid (TAA = AA + dehydroascorbic acid, DHAA), is described. Three assay parameters were investigated and optimized: (1) synthesis of silver nanoparticles (AgNPs) to produce a reliable enhanced localized surface plasmon resonance (LSPR) in the presence of specific added antioxidants; (2) ensuring long-term stability of AA and DHAA in aqueous solutions; and (3) SNaP-C assay conditions to allow for rapid analysis of samples (beverages) by monitoring the enhanced LSPR. The synthesis of AgNPs using soluble starch as a capping agent and d-arabinose as a reducing agent was optimized in a CEM Discover SP laboratory microwave.

Chemical polymerization/oligomerization opens numerous opportunities, from fundamental materials research to practical applications in catalysis, energy, sensing, and medicine. The electrochemical detection of vitamins B (folic acid) and C (ascorbic acid) requires new approaches because of low selectivity, electrode fouling, and interference from other chemicals. As an excellent material for long-term vitamin detection, oligo 3,5-diamino-1,2,4-triazole (oligo DAT) enhances the sensitivity, selectivity, and stability of sensors by creating a stable, conductive layer that facilitates electron transfer and reduces interference from common substances like glucose or uric acid.
