Plasmonic artificial inspector for herbal medicines via surface-enhanced Raman spectroscopy and deep learning.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
For the safety monitoring of herbal medicines (HMs), HM inspectors carry out an organoleptic examination before acceptance for market supply. The organoleptic test processes are often regarded as labor-intensive, thus calling for efficient and reliable aids. Here, we propose a plasmonic artificial HM inspector based on a collaboration between surface-enhanced Raman spectroscopy (SERS) and deep learning (DL). Inherently, a SERS spectrum of an HM specimen contains several peaks that match bioactive compounds in the sample, yielding so-called fingerprint information of HM. Besides, its rapid, few-second data-acquisition speed lends the SERS-DL analysis adaptability to a complementary inspection method for organoleptic examination. Regarding the accuracy and reliability of this new method, the synergistic integration of SERS with DL attains ~95% accuracy in labor-saving differentiation of 35 HM species with similar appearances or of the same genus. Our SERS-DL-based analysis can potentially aid the organoleptic HM inspection and help upgrade the HM database, along with images and other analytical chemistry data.
