Polyelectrolyte Wrapping Layers Control Rates of Photothermal Molecular Release from Gold Nanorods
Gold nanorods show great promise as light-controlled
molecular
release systems. Dye molecules were loaded within a variable number
of polyelectrolyte multilayers wrapped around gold nanorods. The dye
photoinduced release rate depended on the quantity and type of polyelectrolyte
trapping layers and could be tuned by a factor of 100. Only two molecular
capping layers were sufficient to turn off release. Comparison of
the phototriggered molecular release rate to a pure thermal experiment
provides an estimate of the effective temperature of the nanorod solution
upon irradiation
