Polyaniline (PANI) has attracted more and attention due to its excellent sensing performance, conductivity, corrosion resistance. However, the synthesis conditions of PANI are extremely harsh, requiring not only traditional oxidants but also a low-temperature environment. In this study, graphitic carbon nitride (g-C3N4) was prepared into g-C3N4 nanosheet (CN) solution by ultrasonic-assisted liquid-phase exfoliation, CN NO3– were induced at room temperature (R.T.) polymerize metal-free composites (CNPANI).

Detectable quorum signaling molecule via PANI-metal oxides nanocomposites sensors

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: May 2, 2024

Abstract The detection of N-hexanoyl-l-homoserine lactone (C 6 -HSL), a crucial signal in Gram-negative bacterial communication, is essential for addressing microbiologically influenced corrosion (MIC) induced by sulfate-reducing bacteria (SRB) oil and gas industries. Metal oxides (MOx) intercalated into conducting polymers (CPs) offer promising sensing approach due to their effective biological molecules such as C -HSL. In this study, we synthesized characterized two MOx/polyaniline-dodecyl benzene sulfonic acid (PANI-DBSA) nanocomposites, namely ZnO/PANI-DBSA Fe 2 O 3 /PANI-DBSA. These nanocomposites were applied with 1% by-weight carbon paste over working electrode (WE) qualitative quantitative -HSL through electrochemical analysis. impedance spectroscopy (EIS) confirmed the composites’ capability monitor produced SRB-biofilm, limits 624 ppm 441 Furthermore, calorimetric measurements validated presence supporting EIS utilization these MOx/CP offers practical detecting C6-HSL monitoring SRB-biofilm formation, aiding MIC management wells. ZnO/PANI-DBSA-based sensor exhibited higher sensitivity towards compared /PANI-DBSA, indicating its potential enhanced capabilities context. Stability tests revealed ZnO/PANI-DBSA's superior stability both sensors retaining approximately 85–90% initial current after 1 month, demonstrating remarkable reproducibility durability.
