Recent Advancements in Bionic Olfactory Biosensors: Components, Applications, and Future Perspectives.
Review in Chem & bio engineering, 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
Organisms in nature are skilled engineers, equipped with highly evolved sensory systems that enable the precise perception and discrimination of a wide array of environmental stimuli. Among these, the olfactory system exhibits a strong capability to detect and distinguish tens of thousands of odorants with high sensitivity and selectivity. The comprehensive elucidation of the molecular mechanisms underlying human olfaction has laid a solid foundation for the development of bionic olfactory biosensors, which emulate biological olfaction to achieve advanced chemical sensing. These biosensors have introduced novel analytical strategies across diverse fields such as environmental monitoring, medical diagnostics, food safety, and security. Despite considerable progress, challenges persist, particularly in optimizing operational conditions and enhancing the stability and reproducibility of biological recognition elements. This review not only synthesizes recent advancements in the design and application of bionic olfactory biosensors but also provides a comparative analysis of different biological recognition elements, including whole cells, olfactory receptors, odorant-binding proteins, and synthetic peptides. In addition to reviewing sensor architectures and working principles, we also examine nanomaterial-integrated biosensor platforms, highlighting how functional nanomaterials enhance signal transduction and sensitivity. Finally, key application areas are discussed, and current limitations are critically assessed, along with future perspectives for advancing this promising class of biosensors. Through systematic insights into biological sensing mechanisms, material integration, and application-driven requirements, this review offers an integrated perspective on the design principles and future directions of bionic olfactory sensing.
