Two organic compounds namely Acridine (ACD) and 9-aminoacridine (ACD-NH2) have been investigated as electrode materials for an aqueous rechargeable lithium-ion battery (ARLIB) applications. The electrochemical investigations reveal that the active species act as anodes in ARLIB systems. In this regard, nitrogen group act as redox center and undergo electrochemical reaction with Li-ions during charge and discharge process. The synthesis of 9-amonoacridine is done by standard method called chichibabin reaction. Amination of ACD enhances the electrochemical behaviour of the molecule. To improve the electrochemical performances of ACD & ACD-NH2, graphene is used as an additive for ARLIB system. The decorated molecules such as decorated Acridine (dACD) and decorated 9-aminoacridine (dACD-NH2) showed improved electrochemical performance as compared with ACD & ACD-NH2. The decoration is of great importance concerning capacity, reversibility and stability of cycling behavior during charge and discharge processes. Charge/discharge tests show that ACD, ACD-NH2, dACD, and dACD-NH2 have achieved initial discharge capacities of 119, 122, 149 and 220 mAh g -1 respectively at a current density of 0.2 mA. The good cyclic performance and agreeable discharge capacity of the cell signifies the application of dACD-NH2 as anode material for ARLIB system. Copyright © VBRI Press.

An amperometric sensor for detection of toxin aflatoxin B1 from aspergillus flavus based on conducting polyaniline probe using monoclonal anti-aflatoxin B1 (Mc-IgGs-a-AFB1) antibodies after activation with 3% Bovine Serum Albumin (BSA) through electrochemical polymerization has been proposed. The electrode was fabricated by immobilizing Mc-IgGs-a-AFB1 antibodies molecules onto electrode surface and characterized by cyclic voltammetry (CV), scanning electron microscopy (SEM) and fourier transform infrared spectroscopic (FT-IR) etc. The proposed amperometric immune-sensor has demonstrated excellent electro-analytical properties relative to Aflatoxin B1 in a linear range from 0.20 to 1.30 AngmL -1 with a relatively low detection limit of 0.059 AngmL -1 . The present study will help in improving for quantitative determination of mycotoxins in food samples may provide significant improvements in quality control of food safety through a simple, rapid, and sensitive testing system for agricultural products monitoring.
