A 'Plug and Play' Method to Create Water-dispersible Nanoassemblies Containing an Amphiphilic Polymer, Organic Dyes and Upconverting Nanoparticles Khaled M. Arafeh*1, Amir M. Asadirad*1, Jason Woodson Li1, Danielle Wilson*1, Tuoqi Wu*1, Neil R. Branda1 14D LABS and Department of Chemistry, Simon Fraser University Organic dye molecules and oleic acid coated upconverting nanoparticles are not water-soluble. This protocol describes a ‘plug and play’ method that enables the transfer of organic dye molecules and upconverting particles from their initial hydrophobic solvent to water.

Two Colors of Light Are Needed to Break Bonds and Release Small Molecules from the Surface of SiO2-Au Core-shell Nanoparticles Journal of the American Chemical Society. Mar, 2015 | Pubmed ID: 25686633 The photothermal effect is not able to break bonds and release small molecules from the surface of SiO2-Au core-shell nanoparticles unless the nanosystem is first exposed to visible light. Only after this light triggers the ring-opening reaction of dithienylethene chromophores attached to the surface of the nanoparticles can the heat generated by the NIR light induce reverse Diels-Alder reactions.
