Summary: A stable Fe-doped carbon dot nanosol with high catalytic activity was prepared and used for the catalytic amplification of H2O2, leading to the establishment of a new trimode molecular spectral method for the determination of trace H2O2. This method showed a linear range of 5.0 x 10(-10)-2.5 x 10(-8) mol/L and a detection limit of 2.52 x 10(-10) mol/L. The method was successfully applied to the analysis of H2O2 contents in food samples.

Summary: Membrane environments play a vital role in affecting protein structures and functions through protein-membrane interactions in important biological processes. To investigate these effects, we developed lipid-coated nanoporous silver sheets that provide tunable supported lipid monolayer/bilayer environments for in situ surface-enhanced Raman vibrational spectroscopy (SERS) characterizations. By controlling the surface pressure, we can coat lipid monolayer/bilayer on the microscopic curved surface of the silver sheets, mimicking cell membranes and preventing protein denaturation. Our results indicate that lysozyme adopts an α-helical structure in both hydrophilic and hydrophobic interactions with the lipid membrane, while alpha-synuclein folds into an α-helical structure on the negatively charged lipid heads and β-sheet structure on the hydrophobic lipid tails. These observations provide insights into the formation of alpha-synuclein oligomers and its associated amyloid genesis in Parkinson's disease. Therefore, our controllable and tunable lipid platform holds great promise for studying the influence of membranes on protein structures under hydrophilic and hydrophobic effects.

Summary: In this study, a high-performance label-free surface-enhanced Raman scattering (SERS) biosensor was developed for effective screening of colon cancer by combining concentration, separation, and detection. The biosensor, equipped with a centrifuge tube and a filter containing ultrafiltration membranes (UFMs), allowed for the concentration and separation of colon cancer serum. By reducing signal fluctuations and minimizing interference from small molecule proteins, the biosensor improved the accuracy of detection and retained high diagnostic value proteins. Portable Raman spectroscopy combined with PCA-LDA models further enhanced the screening diagnosis of colon cancer.

Summary: In this study, tunable, reliable, and efficient copper nanoelectrodes (CuNEs) were successfully fabricated, and the reversible chemical transformations between aromatic amine and nitro groups on the CuNE surface were comprehensively studied using time-resolved electrochemical surface-enhanced Raman spectroscopy. It was found that the plasmon-mediated chemical reactions (PMCRs) of CuNEs could be well-controlled by changing the surface roughness, oxidation states of copper, and the applied electrode potential. This study demonstrates the importance of Cu nanostructures in investigations of the interplays between PMCR, electrochemistry, and Cu catalysis.

Summary: The control of surface plasmon using metal micro-nano structures and metal/material composites can generate novel phenomena such as optical nonlinear enhancement, transmission enhancement, orientation effect, high sensitivity to refractive index, negative refraction, and dynamic regulation of low threshold. These phenomena have significant potential in fields such as nano-photonics, super-resolution imaging, energy, sensor detection, and life science. Silver nanoparticles, with their high sensitivity to refractive index change, convenient synthesis, and controllable shape and size, are commonly used in surface plasmon sensors. This review summarizes the basic concept, fabrication, and applications of silver-based surface plasmon sensors.
