Polysaccharide-Modified Gold Nanorod and Polydopamine Nanocarriers for Near-Infrared Light-Responsive Biomedical Applications: A Comparative Review.
Review in Molecules (Basel, Switzerland), 2026. 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
Near-infrared (NIR)-responsive nanocarriers offer spatially and temporally controlled heating, drug release, and imaging for biomedical applications. Gold nanorods (AuNRs) and polydopamine (PDA) are two widely investigated platforms with complementary properties: AuNRs provide spectrally tunable plasmonic heating and strong optical imaging capability, whereas PDA offers broadband absorption, adhesive surface chemistry, high cargo-loading capacity, and compatibility with hydrogels and regenerative matrices. Polysaccharide modification can improve physiological stability, reduce nonspecific biological interactions, and introduce receptor targeting, mucoadhesion, or microenvironment responsiveness. This review compares the conjugation chemistry, therapeutic mechanisms, pharmacokinetics, biosafety, and biomedical applications of polysaccharide-modified AuNR and PDA systems, with emphasis on tumor therapy, antibacterial treatment, wound repair, and local drug delivery. AuNR-based platforms are most suitable when rapid wavelength-selective heating and image guidance are primary requirements, whereas PDA-based systems are generally better suited to sustained delivery, tissue adhesion, and long-term local integration. We further discuss AuNR-PDA hybrid architectures and identify key translational barriers, including inconsistent characterization, uncertain long-term fate, nonstandardized photothermal dosimetry, and limited manufacturing reproducibility. This function-oriented comparison provides a practical framework for selecting polysaccharides and carrier platforms according to administration route, biological barrier, therapeutic objective, and safety requirements.
