An electrochemical PAH-modified aptasensor for the label-free and highly-sensitive detection of saxitoxin

Beenish Noureen et al.

Summary: This study developed an electrolyte-insulator semiconductor (EIS) sensor for the label-free detection of saxitoxin (STX), one of the most dangerous shellfish toxins. The sensor was covered with a layer of positively-charged weak polyelectrolyte and utilized a specific aptamer for STX detection. The results showed that the aptasensor had a low detection limit and good selectivity and stability. This sensor provides a convenient approach for the moderate, rapid, and label-free detection of marine biological toxins.

Recent advances in the use of graphitic carbon nitride-based composites for the electrochemical detection of hazardous contaminants

Reddicherla Umapathi et al.

Summary: Graphitic carbon nitride (GCN)-based nanostructures have shown promising applications in electrochemical detection of hazardous contaminants. However, a comprehensive analysis of recent research developments and the use of GCN-based sensing materials in electrochemical detection has not been fully explored. In this review, the synthesis, properties, and applications of GCN composites for the detection of hazardous contaminants were systematically analyzed and reviewed, providing insights into the immobilization methods, modification strategies, advantages, and disadvantages. The potential of GCN-based sensing materials for on-site electrochemical detection of hazardous contaminants and the advantages of on-site electrochemical sensing strategies and portable devices were emphasized.
