Summary: A series of thermally shrinkable polymer surface-enhanced Raman scattering (SERS) substrates were prepared to evaluate the synergistic effect of different known SERS amplification methods in enhancing the Raman signal for low concentration dopamine detection. The results showed that a bimetallic Au and Ag layered structure improved the Raman signal by 5 and 2 times compared to single-layered Au and Ag films. Oxidizing the Ag layer prior to Au deposition further improved the signal by a factor of 2, while adding AuNP on wrinkled films increased the intensity of the Raman signal by another 10 times. The combination of AuNPs with other enhancement methods such as a silver underlayer or surface wrinkling showed a 10 times stronger enhancement. Furthermore, using wrinkling, AuNPs, and a silver underlayer together improved the SERS intensity by more than 3 orders of magnitude.

Summary: This study introduces a novel emission strategy from a 2D ionic hydrogen bond supramolecular network, with high-quality crystals obtained from rapid self-assembly of liquid amine and ketone. The charge-separated transition process and high spin-orbital coupling constants in the rigid supramolecular structure contribute to enhanced singlet-triplet intersystem crossing, leading to stable room-temperature phosphorescence with a maximum quantum efficiency of 26% and a lifetime of 0.45 s. These findings will bring fresh thinking to photoluminescence and other functions purely originated by the supramolecular structure.

Summary: Most current studies on diagnosing diseases through exhaled gas only focus on single markers, but there are actually biomarkers with similar properties corresponding to different diseases. Existing sensing techniques cannot achieve simultaneous multi-label classification of the targets. By introducing multiple hydrogen bond receptors and adjusting the aromatic ring end group, the strength of the interaction between target molecules and the sensor array can be modulated. Sensor responses related to molecular structure can be used as detection characteristics. Through machine learning, different types of amines can be successfully identified, and this method can also distinguish mixed amines at different concentrations in the range of ppm-ppb.
