Bio-Inspired Structural Color Irises as Physical Unclonable Functions for Anti-Counterfeiting.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The global proliferation of high-value commodities has the intensified demand for advanced anti-counterfeiting solutions. Physical Unclonable Functions (PUFs) present a viable authentication mechanism, yet existing implementations exhibit three critical limitations: suboptimal authentication accuracy, insufficient multi-level security architecture, and dependence on costly and specialized equipment for verification. To address these issues, this work utilizes colloidal photonic crystals to fabricate PUF anti-counterfeiting patterns spanning from the macro-to-micro scale. These patterns are integrated with the iris recognition algorithm to construct a multi-layered optical anti-counterfeiting system based on the structural color iris. This work experimentally and computationally demonstrates that the "Ring"-type colloidal photonic crystals originate from the "coffee ring" effect. By modulating the "coffee ring" effect, the size of the colloidal photonic crystal iris patterns can be controlled, enabling switching between "Ring"-type and "Dot"-type colloidal photonic crystals. Furthermore, multiple characteristic parameters confirm that the PUF codes derived from encoded "Ring"-type colloidal photonic crystal images exhibit uniqueness and readability. Finally, a multi-layered anti-counterfeiting system is constructed, comprising three components: structural color patterns, embedded "Morse codes" formed by "Ring"-type and "Dot"-type colloidal photonic crystals, and optical PUF labels based on the "Ring"-type colloidal photonic crystals. This cost-effective system enables low-threshold, high-performance structural color anti-counterfeiting for premium products.
