Galvanic replacement inspired signal amplification: Background-free and antibody-thrift in-situ growth immunochromatography

Rui Shu et al.

Summary: In this study, a galvanic replacement (GR) method was proposed to enhance the color intensity of nanomaterials without the use of reducing agent, thus avoiding drawbacks such as background interference, precipitation, and low reproducibility. The GR-mediated CuS-NS signal amplification was used in lateral flow immunoassay (LFIA) to detect salbutamol, resulting in reduced consumption of antibodies and improved sensitivity.

'Three-To-One' multi-functional nanocomposite-based lateral flow immunoassay for label-free and dual-readout detection of pathogenic bacteria

Leina Dou et al.

Summary: This paper presents a new label-free and dual-readout lateral flow immunoassay (LD-LFIA) method, mediated by a multi-functional nanocomposite. The method simplifies the separation process, exhibits strong adherence and colorimetric detection signal, and improves detection accuracy through the generation of an additional catalytic signal. The results show high specificity and applicability for highly pathogenic Escherichia coli, making it a promising tool for fungal sample testing.
