New synthesized fatty acid amides (N‐(2‐(piperidin‐1‐yl)ethyl)oleamide, and N‐(2‐(pyrrolidin‐1‐yl)ethyl)oleamide) were used for the design of stochastic sensors based on nanographene paste. The stochastic sensors were used for pattern recognition of four amino acids: L‐histidine, L‐tyrosine, L‐ornithine, and L‐lysine in wines. The pattern recognition was performed based on the signatures recorded...
Three stochastic sensors based on nanodiamond (nDP) paste modified with α, β, and γ‐cyclodextrin were designed and characterized for pattern recognition of aspartame, acesulfame K and sodium cyclamate in beverages, ketchup, and biological fluids. The linear concentration ranges obtained for acesulfame K (between 1.00×10−10 mol L−1and 1.00×10−3 mol L−1), for aspartame (between 1.00×10−12 mol L−1 and...
A fast screening method of whole blood was proposed for enantiorecognition of free L‐T3, L‐T4, and D‐T4. Stochastic microsensors based on four inulins (IN, IQ, TEX, and HD) immobilized on diamond paste (DP) were used for recognition of free L‐T3, L‐T4, and D‐T4. For the enantiorecognition of free L‐T4 and D‐T4 in whole blood and pharmaceutical samples, the best microsensor was the one based on TEX/DP...
Stochastic and potentiometric microsensors based on porphyrins and polymeric surfactants such as polysodium N‐undecanoyl‐ l‐leucylvanilate and polysodium N‐undecanoyl‐ l‐vanilate were developed for enantioselective assay of pipecolic acid. The matrices used for the design of the stochastic sensors were diamond paste and graphite paste, while the matrix used for the design of potentiometric sensors...
