The electronic nose is an increasingly useful tool in many fields and applications. Our thermal approach, based on nanostructured metal oxide chemiresistors a gradient, has the advantage of being tiny therefore integrable portable wearable devices. Obviously, wise choice nanomaterial crucial for device’s performance should be carefully considered. Here we show how addition different amounts Au (between 1 5 wt%) Cu2O–SnO2 nanospheres affects performance. Interestingly, best not achieved with material offering highest intrinsic selectivity. This confirms importance specific studies, since chemoresistive gas sensors does linearly affect nose. By optimizing amount Au, device perfect classification tested gases (acetone, ethanol, toluene) good concentration estimation (with mean absolute percentage error around 16%). These performances, combined potentially smaller dimensions less than 0.5 mm2, make this ideal candidate numerous applications, such as agri-food, environmental, biomedical sectors.

Breast cancer is the most commonly diagnosed worldwide, underscoring critical need for effective early detection methods to reduce mortality. Traditional techniques, such as mammography, present significant limitations, particularly in women with dense breast tissue, highlighting alternative screening approaches. Breathomics, based on analysis of Volatile Organic Compounds (VOCs) exhaled breath, offers a non-invasive, potentially transformative diagnostic tool. These VOCs are metabolic byproducts from various organs human body whose presence and varying concentrations breath reflective different health conditions. This review explores potential breathomics, its promise rapid, cost-effective approach cancer, facilitated through integration portable solutions like electronic noses (e-noses). Key considerations clinical translation—including patient selection, environmental confounders, collection methods—will be examined terms how each them affects profile. However, there also challenges variability VOC signatures, standardization sampling protocols. Future research should prioritize standardizing analytical procedures validating their utility large-scale trials.
