Self-Assembly of Nanotriangle Superlattices Facilitated by Repulsive Electrostatic Interactions

SERSly good! Crystallization of triangular gold nanoprisms into close‐packed mono‐ and multilayers is facilitated by electrostatic repulsions. The ordering of the nanotriangles causes an order‐of‐magnitude increase in surface‐enhanced Raman spectroscopy (SERS) enhancement relative to that of disorde...

Description
Summary:SERSly good! Crystallization of triangular gold nanoprisms into close‐packed mono‐ and multilayers is facilitated by electrostatic repulsions. The ordering of the nanotriangles causes an order‐of‐magnitude increase in surface‐enhanced Raman spectroscopy (SERS) enhancement relative to that of disordered assemblies.
