Application of aggregation-induced emission materials in gastrointestinal diseases

Figure 2 Dual-correspondence system based on gold nanoparticles and aggregation-induced emission luminogens enhances detection of gastrointestinal pathogens. Due to the aggregation of gold nanoparticles, the colorimetric signal increases, while the fluorescence signal of aggregation-induced emission luminogens decreases due to the inner filter effect, resulting in a bidirectional complementary colorimetric/fluorescent signal response. When combined, they exhibit a more sensitive bimodal immunoassay. AIEgens: Aggregation-induced emission luminogens; AuNPs: Gold nanoparticles. Created in Figdraw.
