“…In addition, the band at 1613 cm −1 and 1730 cm −1 correspond to benzene skeleton vibration and C O of the ester groups of abamectin, respectively. 23,37–40 It is noted that the peak intensities of abamectin increase with an increase of Si pyramid size. This finding indicates that the large pyramids lead to a signal enhancement more efficiently than do small pyramids.…”

Tumors are characterized by abnormal cell growth, which leads to uncontrolled cell proliferation, invasion of surrounding tissues, and potential metastasis to other parts of the body. Current treatments for tumors include surgery, chemotherapy, radiotherapy, targeted therapy, and biological therapy. However, many tumors are detected at advanced stages, limiting the effectiveness of these treatments. Therefore, there is a need to develop more sensitive and efficient techniques to improve patient survival rates. Surface‐enhanced Raman scattering (SERS) technology is a highly sensitive molecular detection and characterization technique. It can be combined with histomorphology, immunolabeling assays, and molecular hybridization to achieve quantitative diagnosis at morphological, molecular, and genetic levels. SERS offers advantages such as objectivity, reproducibility, and comparability. However, there are challenges to address, including complex substrate or probe preparation, cumbersome data analysis, and signal reproducibility and reliability. To fully utilize the potential of SERS in the biomedical field and for clinical translation, it is important to optimize the technology and develop more sensitive, accurate, and reliable substrate or probe preparation and analysis methods. This review aims to comprehensively explain the mechanism and unique advantages of SERS technology and discuss its current status, challenges, and prospects in tumor‐related research.

“…Therefore, uniformity and stability are key constraints that seriously affect the practical application of SERS, regardless of how well they have been enhanced in laboratory settings. Therefore, a lot of resources have been devoted to fabricating large-scale SERS substrates that have high-density hot spots as well as good uniformity [24][25][26]. For example, anodic aluminum oxide (AAO) film is used as a template to fabricate large-scale, 3-dimentionally assembled Au nanobipyramid (Au NBP) films [27][28][29].…”

Surface-enhanced Raman spectroscopy (SERS) has been proven to be a promising analytical technique with sensitivity at the single-molecule level. However, one of the key problems preventing its real-world application lies in the great challenges that are encountered in the preparation of large-scale, reproducible, and highly sensitive SERS-active substrates. In this work, a new strategy is developed to fabricate an Ag collide SERS substrate by using cetyltrimethylammonium bromide (CTAB) as a connection agent. The developed SERS substrate can be developed on a large scale and is highly efficient, and it has high-density “hot spots” that enhance the yield enormously. We employed 4-methylbenzenethiol(4-MBT) as the SERS probe due to the strong Ag–S linkage. The SERS enhancement factor (EF) was calculated to be ~2.6 × 106. The efficacy of the proposed substrate is demonstrated for the detection of malachite green (MG) as an example. The limit of detection (LOD) for the MG assay is brought down to 1.0 × 10−11 M, and the relative standard deviation (RSD) for the intensity of the main Raman vibration modes (1620, 1038 cm−1) is less than 20%.
