Laser-induced graphene electrochemical sensor for quantitative detection of phytotoxic aluminum ions (Al³⁺) in soils extracts.

ABSTRACT: Aluminum in its Al³⁺ form is a metal that inhibits plant growth, especially in acidic soils (pH < 5.5). Rapid and accurate quantitative detection of Al³⁺ in agricultural soils is critical for the timely implementation of remediation strategies. However, detecting metal ions requires time-consuming preparation of samples, using expensive instrumentation and non-portable spectroscopic techniques. As an alternative, electrochemical sensors offer a cost-effective and minimally invasive approach for in situ quantification of metal ions. Here, we developed and validated an electrochemical sensor based on bismuth-modified laser-induced graphene (LIG) electrodes for Al³⁺ quantitative detection in a range relevant to agriculture (1-300 ppm). Our results show a linea
