Direct lysis combined with amplification-free CRISPR/Cas12a-SERS genosensor for ultrafast and on-site identification of meat authenticity.

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
A novel direct lysis method combined with amplification-free CRISPR/Cas12a-SERS genosensor was for the first time developed to rapidly and sensitively identify meat adulteration. Notably, polystyrene (PS) microspheres, with distinct shrinking and swelling properties, were dexterously employed to encapsulate biological-silent Raman reporter 4-mercaptobenzonitrile (4-MBN) and act as a controlled-release signal probe. Target DNA activated the trans-cleavage activity of CRISPR/Cas12a towards ssDNA linked with PS microsphere to liberate the signal probe, which was able to release numerous Raman reporters after treatment with THF solution, resulting in high signal amplification. Through this platform, trace target DNA was deftly transformed into a sensitive Raman signal and could be on-site determined through a portable Raman equipment. Under optimized conditions, this strategy displayed good linearity in the range 1-450 ng/μL (R
