A Nanofilm-Based Fluorescent Sensor toward Highly Efficient Detection of Ethephon
Ethephon (ETH) is widely used to promote fruit ripening and improve fruit quality. However, improper use is harmful to human health and to the environmental safety. Therefore, development of the techniques for on-site and at real-time monitoring of ETH is of importance for its safe use. In this work...
