Hi everybody: i am looking for recent datas about the amount of registered biocides containing silver nanoparticles. The most recent data i found is in this paper from Nowack et al. (2011) which explains that about the 53% of biocides registered at EPA contains nanoAg and the 7% of it contains AgNPs. I looked for more recent datas/numbers about biocides cointaining nanoAg/AgNPs, but from main sites like EPA's, REACH's and ECHA's or from the huge amount of papers i read nothing came out. I was wondering if someone has something (papers, reviews, sites etc..) to share with me to help my research. Everything is accepted but it must be referred to biocides containing nanoAg/AgNPs.

Thanks a lot to everyone who will share his/her time with me
