Low-Cost Electrochemical Ethylene Sensor for Agricultural Applications

NON-TECHNICAL SUMMARY: Ethylene (ethene) is a plant hormone that is active at very low concentrations in the developmental and reproductive processes of plants. Ethylene plays a crucial role in the complex processes of ripening and senescence of fruit, vegetable and floral crops, making this unique sensor a valuable tool for U.S. agriculture. The anticipated result of the Phase I and Phase II program would be a low-cost ethylene monitor with high selectivity and sensitivity. A convenient, inexpensive sensor could be used to improve agricultural ripening and storage practices resulting in improved quality and cost of fruits and vegetables. The instrument could be used for basic research on plant physiology, for monitoring ethylene in storage or transportation of fruits, vegetables, and flowers (cut or live), and for measuring ethylene in ripening operations. It could be used in a laboratory, greenhouse, shipping container, wholesale or retail storage facility or even a home refrigerator.
