英文摘要Background: Mineralogical detection faces challenges due to the diversity of minerals, analytical complexity, variable conditions, and limitations in equipment portability and cost. Traditional techniques such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) offer elemental and structural characterization but face limitations in portability and cost, and often require sophisticated sample preparation. Raman spectroscopy, a non-destructive and highly selective analytical technique, is limited by weak signals and overlapping peaks in complex samples. To address these limitations, we introduce a novel surface-enhanced Raman spectroscopy (SERS) nanoprobe, MB@Au@Fe3O4, designed for the detection of semiconductor minerals. Results: In this paper, a surface-enhanced Raman spectroscopy (SERS) probe, methylene blue (MB)-Au@Fe3O4 core-shell (MB@Au@Fe3O4) composite, was designed to detect and identify semiconductor minerals. The nanoprobe utilized MB as the SERS signal molecule and Au as the SERS enhancement substrate, while incorporated magnetic Fe3O4 to drive the nanoprobe proximity to the reaction interface. The nanoprobe utilizes photocatalytic degradation of MB to transduce semiconductor activity into recordable SERS signal changes, enabling rapid and sensitive detection of FeS, FeS2, and FeOOH. Experiments demonstrated that the nanoprobe successfully differentiates these minerals based on their intrinsic photocatalytic capabilities, with high sensitivity and specificity. Moreover, the MB@Au@Fe3O4 nanoprobe was applied for in situ inspection of corrosion products beneath biofilms, demonstrating its potential for practical applications in complex environments. Significance and novelty: The MB@Au@Fe3O4 nanoprobe offers a practical and innovative solution for the rapid and sensitive detection of semiconductor minerals in complex environments. This approach overcomes the limitations of traditional techniques, providing enhanced sensitivity and specificity without the need for largescale equipment or complex sample preparation. The findings highlight the potential for on-site detection and monitoring of semiconductor minerals in various real-world applications.
