I participated the 32nd international conference on Nanoscience, Nanotechnology and Nanoengineering from 18th to 19th November (Rome, Italy) thanks to the support of the Project GAJU 080/2019 Z Hao. This conference invited participants from all over the world and included keynote presentations, oral talks, poster presentations. I gave an oral presentation focus on ‘Optimization of alginate edible coatings incorporated with essential oil emulsion: Physical and antibacterial properties’ on the conference.
