Introduction ZnO nanorods with a wide band gap of 3.37 eV and large exciton binding energy of 60 meV at room temperature are considered the most promising, highly sensitive materials for sensors because of their slow electron/hole recombination rate, high surface-to-volume ratio, faster response, higher optical gain, and specific crystalline orientation.

Before being applied to food packaging materials, fish gelatin must be modified to reduce their water solubility[3].
Materials and methods Materials The tilapia skin gelatin power was prepared by our laboratory. 4-hydroxy-3-methoxycinnamic acid (ferulic acid, BR) and linoleic acid (BR) were purchased from Sigma Chemical Co.
