What is Eugenol and Carboxymethyl Cellulose Derived Nanocoating with Insect Repellent and Long-term Antibacterial Activity about?

Eugenol (EUG) is a natural compound with antibacterial and insect repellent activity. Its processing, utilization, and storage are limited due to its strong volatility, instability, and low solubility in water. In this study, an amphiphilic polymer-based nano-green coating (CMC-CYST-EUG) based on carboxymethyl cellulose (CMC) has been prepared, EUG was grafted into CMC by thiol-ene click reaction of Cysteamine hydrochloride (CYST) to reduce the volatility of EUG. When exposed to the same environment, the antibacterial duration of CMC-CYST-EUG increased by 7.8 times compared with pure EUG. Liquid holding capacity of CMC-CYST-EUG on pakchoi leaf surface increased by 81% compared with EUG solution. It shows that CMC-CYST-EUG has good adhesion to fruits and vegetables and can prevent the loss of EUG. Strawberry treated with CMC-CYST-EUG can be stored for 7 days. Within the concentration range of 0.5-0.25 mg/mL, the antifeedant rate of CMC-CYST-EUG to pests was significantly higher than that of EUG. Importantly, cytotoxicity tests show that CMC-CYST-EUG is considered safe at low concentrations. This synthetic material provides a strategy for the development and utilization of volatile a
