Characterization and optimization of biogenic copper nanoparticles synthesized by Pseudomonas putida with cytocompatibility investigation.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
One area of science that is experiencing rapid growth is nanotechnology. The goal of nanotechnology research is to develop novel, economical, safe, and effective methods for creating nanoparticles. This study presents a green, cost-effective, and environmentally friendly method for synthesizing copper nanoparticles (CuNPs) using the bacterium Pseudomonas putida. The biosynthesis process was optimized by manipulating the growth medium with various carbon sources, resulting in Pp-CuNPs approximately 91.28 nm in diameter with a surface plasmon resonance (SPR) at 550 nm. Characterization techniques as Fourier transmission infrared (FTIR) and High-resolution transmission electron microscope (HR-TEM) confirmed the successful formation and stability of the nanoparticles, with a surface charge indicating good colloidal stability. Cytocompatibility assessments demonstrated high safety of Pp-CuNPs for lung Wi38 normal cell lines, supporting their potential applications in pharmaceutical, agricultural, and environmental fields. The findings underscore the feasibility and advantages of microbial-mediated copper nanoparticles (CuNPs) production, as well as their promising biomedical and ecological applications.
