A novel dual-mode immunosensing platform integrating photoelectrochemical (PEC) and colorimetric detection was developed for the early and reliable determination of the non-small cell lung cancer biomarker cytokeratin 19 fragment (Cyfra21-1). An ordered ReS2/In2S3 type-II heterojunction array was constructed, which n...

Developing highly sensitive and stable electrochemiluminescence (ECL) biosensing platforms requires overcoming inherent limitations, such as aggregation-caused quenching (ACQ) of luminophores and coreactant-induced electrode passivation. In this work, we developed an ECL biosensor capable of detecting microcystin-LR...
Acetamiprid (ACE) is a widely used neonicotinoid insecticide with high insecticidal efficacy; however, its residues in food and environmental matrices have raised concerns regarding potential risks to human health. In this work, a DNA walker amplification strategy integrating the dual electrochemiluminescence (ECL) que...
