Oct 2021: Physiological and Metabolic Responses of Maize (Zea mays) Plants to Fe3O4 Nanoparticles





Dear PhotosynQ User,


Welcome to the PhotosynQ community newsletter!


We have the following study by Yan et al. (2020) as our featured project. This project used MultispeQ to measure chlorophyll fluorescence of maize plants in response to Fe3O4 nanoparticles.

We hope you enjoy reading our selected study and using PhotosynQ technology.


Please stay safe and healthy! Best, PhotosynQ Team

Physiological and Metabolic Responses of Maize

(Zea mays) Plants to Fe3O4 Nanoparticles

Science of The Total Environment https://doi.org/10.1016/j.scitotenv.2020.137400


This study aimed to provide an insight into the impact of Fe3O4 nanoparticles on plants.


Authors used MultispeQ to measure relative chlorophyll content, LEF, and Phi2 of maize leaves exposed to 0, 50, and 500 mg/kg Fe3O4 nanoparticles.

There were no significant differences in relative chlorophyll content, LEF, and Phi2 among the treatments. This study concludes that Fe3O4 nanoparticles at 50 and 500 mg/kg have limited toxic effects on maize.
