EC50 values for silver nanoparticles (bare or capped with citrate or cysteine) Ceriodaphia dubia?

23 May 2020 0 7K Report

Hello to everybody. I am looking for EC50 values for bare or capped (cysteine or citrate) silver nanoparticles to compare with the values i've obtained in my tests with freshwater microcrustacean Ceriodaphnia dubia; this exclude other species Daphnia similis.

Thanks to everyone who will dedicate his/her time to help me.
