Metal-Free Peptide Semiconductor-Enhanced Raman Scattering.
Article in Nano letters, 2024. 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
There is a growing demand for sustainable and safe materials in developing technological systems and devices, including those that enhance Raman scattering. Organic (bio) materials based on simple peptides are one class of such materials. This study investigates self-assembled semiconducting peptides as metal-free substrates for surface-enhanced Raman scattering. Our results reveal significant variations in Raman enhancement factors, spanning up to 2 orders of magnitude. We examined specific Raman enhancement selection rules related to the energy levels and structural configurations of the probe molecules. The effectiveness of these rules underscores the importance of strong molecule-peptide coupling and efficient charge transfer for achieving optimal Raman enhancement factors. These insights offer a foundational understanding of peptide-molecule interactions and the underlying chemical mechanisms driving Raman enhancement, highlighting the potential of organic semiconductor-based materials as highly effective platforms for enhancing Raman scattering in chemical sensing applications.
