The interactions between CoA, Ag(I), and the chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) were thoroughly examined, leading to the development of a highly sensitive and specific assay for HAT detection. Notably, this method utilizes Ag(I) to catalyze the oxidation of TMB without the need for H₂O₂, simplifying the reaction system. Our results show that CoA effectively inhibits the catalytic activity of Ag(I) in a non-competitive fashion, offering a robust means to quantify HAT activity in CTCs.

Comprehensive analysis across various cell types, including normal cells, gastric cancer cells, and simulative CTCs, revealed that HAT activity was highest in CTCs, underscoring their critical role to some extent in tumor metastasis. Furthermore, stimulation with epidermal growth factor (EGF) and tumor necrosis factor-α (TNF-α) demonstrated distinct HAT activity patterns in different cells, highlighting their differential responses to growth and inflammatory signals.

Upon 980 nm laser irradiation, D/UCMSA emit up-converted light at 660 nm, which activates the loaded methylene blue (MB) to produce singlet oxygen (¹O₂) for PDT. Simultaneously, the down-converted emission at 1525 nm serves as a reference signal for ratiometric imaging.

Upon 808 nm laser excitation, this ligand exchange process activates fluorescence emission at 1085 nm.

We developed a multi-signal, reverse-transcription-free lateral flow assay for detecting respiratory syncytial virus (RSV) RNA fragments. This assay leverages a chimeric tetrahedral probe combined with an entropy-driven, 'one-stone-two-birds' strategy for enhanced signal amplification. The tetrahedral chimera carries two sorts of capture probes that recognize and capture different signal strand inputs. Entropy-driven circuits (EDC) generate abundant waste chains via a self-feedback cascade reaction, including two biotin-labeled single strands and one duplex. As reporter tags, the two biotinylated single-stranded chains can be simultaneously matched and captured by tetrahedral chimera during one time of sample flow, bridging horseradish peroxidase-coupled streptavidin-modified gold nanoparticles onto the strip to induce coloration. In this process, every EDC cycle can achieve dual signal outputs, akin to \"killing two birds with one stone\" in the atom-economic signal amplification. Furthermore, the gold nanoparticles carry amounts of horseradish peroxidase, serving as catalytic amplified labels to enhance the colorimetric signal. The strip achieves a broad linear dynamic range and a detection limit of 0.1fM with high specificity for RSV detection.
