Owing to its inherent advantages—such as being non-destructive, rapid, highly molecule-specific, and minimally interfered with by moisture—Raman spectroscopy has been widely adopted in the fields of skin barrier function assessment, monitoring the transdermal penetration of active cosmetic ingredients, and the identification and quality control of cosmetic products. Despite these strengths, the practical application of this technique faces a significant bottleneck: the strong fluorescence background generated by endogenous skin components and exogenous cosmetic additives. Endogenous skin substances, such as structural proteins (e.g., collagen and elastin), metabolic coenzymes (e.g., nicotinamide adenine dinucleotide), and pigments (e.g., melanin), together with exogenous cosmetic constituents like organic colorants, chemical sunscreens, and fragrances, often possess strong absorption and emission characteristics. When excited by lasers, these components produce a fluorescence background that can be 106 to 108 times stronger than the Raman scattering signals, effectively masking the inherently weak vibrational fingerprint information. In recent years, driven by the rapid development of optoelectronic hardware and artificial intelligence algorithms, fluorescence suppression strategies have evolved from isolated, single-method approaches into comprehensive, multi-level synergistic systems. These systems are categorized into three distinct tiers: sample preparation, signal acquisition, and data processing. At the sample preparation level, techniques such as photobleaching and surface-enhanced Raman spectroscopy (SERS) are employed to eliminate or bypass the generation of fluorescence at the source. At the signal acquisition level, instrumental improvements—including the use of long-wavelength near-infrared excitation (typically 785 nm or 1 064 nm), confocal spatial filtering, and shifted excitation Raman difference spectroscopy (SERDS)— are utilized to physically isolate Raman signals from the fluorescence background. Furthermore, at the data processing level, numerical baseline correction methods such as polynomial fitting, penalized least squares (e.g., airPLS, arPLS), wavelet transform, and derivative algorithms are increasingly integrated into the analytical pipeline to extract Raman spectral features from mixed signals without increasing hardware costs or acquisition time. This review provides a systematic categorization and critical evaluation of these fluorescence suppression methods, detailing their underlying principles, technical advantages, and inherent limitations in diverse experimental setups. By focusing on critical application scenarios—including skin barrier assessment, percutaneous absorption monitoring, the routine quality control of cosmetics, and the emerging field of portable on-site detection—this paper explores the current state of technique selection and optimization. Finally, the article discusses future development trends, emphasizing the necessity of constructing adaptive, tiered suppression strategies, developing intelligent and automated data processing algorithms, and promoting the integration of portable, multi-modal diagnostic devices. The objective of this review is to provide a comprehensive technical reference to facilitate the transition of Raman spectroscopy from a specialized laboratory tool into a routine, robust analytical platform for advancements in skin science and cosmetic research.

Ischemic stroke(IS)research has faced bottlenecks due to the limitations of conventional technologies in resolving cellular heterogeneity and spatiotemporal dynamics.The development of single-cell and spatial omics technologies provides revolutionary tools to break through these constraints.Single-cell omics technologies,by performing high-throughput sequencing on thousands of cells,reveal the high heterogeneity and dynamic state transitions of neurons,glial cells,immune cells,and others post-IS.For instance,microglia contain pro-inflammatory and anti-inflammatory functional subsets,while astrocytes exhibit distinct activation state spectra.Pseudotime analysis further reconstructs the fate trajectories of cells during the damage and repair processes.Spatial omics technologies,conversely,reconstruct spatial maps of gene expression through in situ capture,elucidating molecular gradients between the ischemic core,penumbra,and healthy brain regions,and enabling the analysis of critical cell-cell interaction net-works.Integrating the deep phenotyping capability of single-cell sequencing with the in situ localization information from spatial omics constitutes the current core strategy.This multimodal analysis allows for precise anchoring of cell subtypes to their spatial microenvironments,revealing their distribution patterns and functions,and constructing a more accurate atlas of cell-cell communication.This significantly ad-vances the refined dissection of IS mechanisms.This strategy has already accelerated the discovery of po-tential biomarkers and spatiotemporally specific therapeutic targets.Although challenges remain in sample preparation,data integration,and technical noise,future interdisciplinary collaboration,multi-omics in-tegration,and in-depth mining with artificial intelligence promise to comprehensively transform our under-standing of IS.Ultimately,it holds the potential to promote advances in its early diagnosis,precise sub-typing,and the development of individualized treatment strategies.
