title: Synthesis of branched Au nanoparticles with tunable near-infrared LSPR using a zwitterionic surfactant.
abstract: Asymmetric branched gold nanoparticles are obtained using for the first time in the seed-growth approach a zwitterionic surfactant, laurylsulfobetaine, whose concentration in the growth solution allows to control both the length to base-width ratio of the branches and the LSPR position, that can be tuned in the 700-1100 nm near infrared range.
