“…An enantioselective SPR sensor based on C 60 fullerene‐glutathione SAM was used for the enantiorecognition of L‐histidine. The results obtained using this SPR sensor are comparable to those obtained using the enantioselective, potentiometric membrane electrode based on C 60 fullerene . Establishing the mechanism of enantiorecognition is essential at this point.…”

“…The interaction between C 60 fullerene and L‐histidine is based on hydrogen bonding interaction. the experimental results obtained using the enantioselective SPR sensors and the enantioselective, potentiometric membrane electrode based on C 60 fullerene proved that only L‐histidine is bound with C 60 fullerene. No bond was observed in either experiment between C 60 fullerene and D‐histidine (Fig.…”

A novel enantioselective surface plasmon resonance (SPR) sensor based on a self-assembled monolayer of C60 fullerene as the chiral selector is proposed. A binding assay, apparent affinity constant, and apparent dissociation binding constant were used to analyze and study the enantioselectivity of C60 fullerene-glutathione film for L-histidine, which was chosen as the model analyte. The apparent affinity constant for the complex formed by L-histidine with C60 fullerene-glutathione film was 5.2 x 10(9) M(-1). The proposed SPR sensor can be used for the assay of L-histidine in the 10(-10)-10(-7) mol/L concentration range.

“…Enantioanalysis became an area of great interest because of its importance in biomedical, pharmaceutical, environmental, and food areas. 1,2 Malic acid (C 4 H 6 O 5 ) ( Figure 1) is usually found in vegetables, apples, and juices, contributing to their flavors and tastes. [3][4][5][6][7] Malic acid is also an indicator of wine maturation.…”

Single-walled carbon nanotube-(7,6) chirality was used for the design of multimode enantioselective sensors using different carbon matrices such as graphene paste, graphite paste, and carbon nanopowder-based paste. Land D-malic acids were used as model analytes. The responses of the multimode sensors were evaluated for potentiometric and differential pulse voltammetry (DPV) modes. When carbon nanopowder was used as matrix, the multimode sensor was enantioselective for D-malic acid in the concentration range 10 −3 to 10 −15 mol/L for the potentiometric mode and 10 −5 to 10 −8 mol/L for the DPV mode. The graphite paste-based sensor was enantioselective for L-malic acid in the ranges: 10 −10 to 10 −13 for the potentiometric mode and 10 −4 to 10 −7 mol/L for the DPV mode. The sensors based on graphene and chiral single-walled carbon nanotubes were enantioselective for D-malic acid, and a response was obtained only in the DPV mode. Accordingly, the matrix influenced both the enantioselectivity and the sensitivity of the measurements. The application of the sensors was for the enantioanalysis of malic acid in wines and apple juice samples. The proposed method is fast and reliable and allows the quantification of Land D-malic acids using electrochemical methods based on different principles, from the real samples after a buffering of the samples. The enantioanalysis of malic acid in wine and juice samples was performed with high recoveries (higher than 90.00%) and low relative standard deviation (RSD) (%) values (lower than 1.00%).
