The multistrata nanoparticle is the culmination of tunable, dual-peak, UV–vis–NIR spectrum extinction characteristics, trimodal imaging contrast, simple synthesis, and facile surface modification capabilities into a single <60 nm diameter, novel, multifunctional, multilayered nanosphere that seeks to relieve current methodological limitations by coupling diagnostics and therapeutics into one single theranostic tool.
