Summary: A novel sandwich-typed electrochemical immunosensor was developed for ultrasensitive detection of breast cancer biomarker HER2. The sensor utilized core-shell Au@PdAg dog-bone-like nanorods as electrode material and PtRh nano-islands on Au NRs as the secondary antibody bioconjugates. This strategy showed excellent performance for HER2 detection with a broader linear range and lower detection limit, offering a constructive method for determination of other biomarkers in clinic.

Summary: In this report, Au@Ag core-shell nanorod structures were developed for contaminants sensing by SERS. The silver shell thickness and plasmon wavelength were tuned by changing coating time and silver precursor amount. These structures showed ultra-sensitive detection ability for Nile blue A dye and Fenobucarb pesticide sensing. The Au@Ag core-shell sample with minimal silver shell thickness exhibited the highest Raman enhancement factor due to optimal enhancement of the electromagnetic field of bimetallic structures. This report demonstrates the potential applicability of combining unique features of two plasmonic metals in SERS-based analysis.

Summary: The irradiation of colloidal Au@Ag core-shell nanorods with femtosecond laser pulses can produce bimetallic heterostructures and alloyed plasmonic nanocrystals with different morphologies and degrees of alloying. Advanced electron microscopy techniques and EDX tomography can reveal the morphology and elemental distribution of the irradiated nanoparticles and their optical properties. The method shows potential for the fabrication of unique multielemental nanoparticles for various applications such as catalytic, plasmonic, and magnetic applications.

Summary: Nanozymes, with biocatalytic properties, are used as artificial enzymes to overcome the limitations of natural enzymes. Ligand-free PtAg nanoclusters are synthesized and applied as nanozymes, exhibiting good catalytic activity for various enzyme-mimicking reactions. Comparison between PtAg nanoclusters and PtAg nanoparticles reveals a converse dependency of Ag-loading on their activity. This study contributes to the field of nanozymes and presents a potential option for ligand-free bimetal biocatalysts.

Summary: This work presents a controllable, green, and facile strategy for preparing Au NRs@MnO2 core/shell nanosheets using the LSPR effect of gold nanorods. MnO2 is obtained through the reduction of KMnO4 with photoelectrons induced by the LSPR effect. Methanol is found to be significant in maintaining the shape of Au nanorods by acting as a hole scavenger, and the OER performance of the resulting Au NRs@MnO2 is notably enhanced under proper irradiation and stable after 1000 cycles.

Summary: In this study, PtAuAg@PtAg hollow nanodendrites were synthesized using a seed-mediated method, showing excellent catalytic performance for ethylene glycol oxidation reaction (EGOR) and methanol oxidation reaction (MOR). Among them, Pt38Au29Ag33 HNDs exhibited the highest mass activity, 4.2 times and 5.3 times higher than commercial Pt/C, and retained high activity after cyclic voltammetry tests. The superior catalytic performance of PtAuAg@PtAg HNDs is attributed to their unique structure increasing surface area and active sites, as well as synergistic effects among Pt, Au, and Ag.
