Reported herein is the immobilization of N-(1-naphthyl)ethylenediamine (NED) on cellulose via an epichlorohydrin (ECH)-based covalent attachment and the implementation of the functionalized cellulose into an ultrasensitive, paper-based device for nitrite detection. The reported functionalization procedure resulted in a 12.9-fold higher functionalization density than the density that results from the previously reported procedures, and the subsequent device allows for nitrite detection limits in synthetic freshwater and real seawater of 0.26 and 0.22 μM, respectively. The sensor is efficient in a wide range of temperature, humidity, turbidity, and salinity conditions and has been successfully applied for nitrite detection in real water samples.

通过将N-（1-萘基）乙二胺接枝到纸基设备中的纤维素实现亚硝酸盐的超灵敏检测。
本文报道的是通过基于环氧氯丙烷（ECH）的共价连接将N-（1-萘基）乙二胺（NED）固定在纤维素上，以及将功能化纤维素实现为用于亚硝酸盐检测的超灵敏纸基设备。报告的功能化程序导致的功能化密度比以前报告的程序高12.9倍，随后的设备允许合成淡水和实际海水中亚硝酸盐的检出限分别为0.26和0.22μM。该传感器在广泛的温度，湿度，浊度和盐度条件下均有效，并且已成功应用于实际水样中的亚硝酸盐检测。
