The growing understanding of the unique physical and chemical properties of the nanoparticles is constantly revealing novel applications from catalysis,drug delivery,sensors,energy storage,etc1.Despite their transformative potential,their implementation is limited due to the lack of manufacturing technologies for their large scale production.The overall objective of our work is the development of novel micro-tubular reactors for the continuous synthesis of ligands-free metal nanoparticles with controllable and tunable sizes.While the laminar flow regime characteristic of micro-devices allows the synthesis of the particles in the absence of stabilizing or capping ligands without agglomeration,it also leads to poly-dispersed sizes in the resulting particles caused by its characteristic parabolic velocity profile.Typical strategies to avoid this effect such as bi-phasic or Taylor flow systems in microreactors2 lead to agglomeration in the absence of stabilizing ligands.
