These nanocomposites were synthesized through a judicious combination of Polyaniline (PANI), reduced Graphene Oxide (rGO), and Zinc Oxide (ZnO). The physical properties of PrGZs were characterized using techniques such as Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Scanning Electron Microscopy (SEM). The electrochemical performance of PrGZs was evaluated using Electrochemical Impedance Spectroscopy (EIS) and Differential Pulse Anodic Stripping Voltammetry (DPASV) with a carbon paste electrode (CPE). Notably, PrGZ-2 exhibited significantly improved detection and sensitivity compared to the individual components and binary composite, attributed to its low resistance, pseudo-capacitive behaviour, and enhanced electron transfer properties. The calculated limits of detection (LOD) and quantification (LOQ) for PrGZ-2 were 0.3 μM and 1.16 μM, respectively, within a Pb²⁺ ion concentration range of 1 μM–5.5 μM. This indicates good sensitivity for low concentration detection, with an R² value of 0.994. The relative standard deviation (RSD) for PrGZ-2 was 2.13 %, confirming acceptable repeatability and precision of the measurements on the working electrode at a scan rate of 0.01 V/s. Furthermore, the composite material displayed good results in the presence of interfering metals and demonstrated appreciable repeatability and stability. These findings suggest that the material holds significant potential and could be evaluated for detecting other toxic heavy metals, expanding its application for environmental monitoring without interference from lead.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 6","pages":"Article 101718"},"PeriodicalIF":3.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique of repairing concrete cracks using bacteria has been widely accepted because of its effectiveness in enhancing concrete characteristics, such as strength and durability. However, no research has yet been conducted on predicting the formation of calcium carbonate (CaCO₃) using different bacteria with organic calcium-based nutrients, such as bamboo. This study investigated two bacteria, <em>Bacillus subtilis</em> (<em>B. subtilis</em>) and <em>Bacillus cereus</em> (<em>B. cereus</em>), cultured in Bamboo Dust Nutrient (BDN) media to evaluate their survivability and acceptance in this environment. Furthermore, the ability of these bacteria to form CaCO₃ is validated through microstructural analysis using XRD, SEM and EDX. To quantify CaCO₃ formation in the presence of BDN, the bacteria were cultured separately in Luria (L) broth and Luria Bertani (LB) broth. Additionally, the concentration of the BDN solution, boiling temperature, and boiling duration were considered as input parameters for establishing the optimal nutrient dose for CaCO₃ formation through optimization techniques. The optimization of CaCO₃ formation by these bacteria was performed using Response Surface Methodology (RSM). The models were developed based on the Central Composite Design (CCD) approach in Design Expert software and analyzed using the ANOVA tool to simplify the design model. Based on model analysis, the highest CaCO₃ formation was observed with B. subtilis in LB broth (29.115 mg), followed by B. cereus in LB broth (27.788 mg). The desirability values (&gt;0.90) indicate effective optimization of the nutrient dose, boiling duration, and temperature conditions. These findings confirmed the feasibility of using bacterial-induced mineralization as a self-healing agent in construction materials. Finally, the self-healing capability of <em>B. subtilis</em> in the presence of BDN was demonstrated by injecting a bacteria-embedded BDN solution into cement mortar.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 6","pages":"Article 101715"},"PeriodicalIF":3.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
