Abstract
The present invention relates to an adduct comprising metal particles and an adduct between an sp2 carbon allotrope and a pyrrole compound. In particular, the invention relates to an adduct comprising metal nanoparticles (NPs) and hydrophylic adducts between a sp2 carbon allotrope and a pyrrole compound. The metal preferentially copper, silver or gold. Such adduct is preferentially used for anti-bacterial activity.
