In recent years, nano(bio)sensors have revolutionized horticulture by enabling real-time monitoring and precise data collection. These miniature devices incorporating nanomaterials contribute significantly to the renaissance of horticulture through several key applications. They allow for early disease detection by sensing subtle changes in plant physiology, thus enabling targeted actions to prevent crop losses. In nutrient management, nano(bio)sensors measure nutrient levels in soil and plant tissues, providing accurate data to optimize fertilization strategies. For water management, these sensors monitor soil moisture, aiming to implement efficient irrigation practices, which is crucial in addressing water scarcity. Additionally, they enhance pest surveillance by detecting infestations promptly, reducing reliance on chemical pesticides, and promoting more effective integrated pest management. During post-harvest handling, these sensors assess fruit ripeness, freshness, and quality, guiding timely harvesting and storage decisions to ensure produce quality. By providing real-time, accurate data on plant and soil health, these advanced sensors enable more informed decision-making, ultimately fostering the renaissance of horticulture through improved productivity and resource efficiency.
