Selective heating of multiple nanoparticles as a new strategy for controlled release applications

[摘要] This was accomplished by the laser excitation at two different wavelengths corresponding to both of the nanorods;; absorption peaks. The releases were very selective, efficient, and externally tunable by adjusting the laser fluence. The released DNA oligos were still functional. This concept is expandable to beyond two species. Its thiol conjugation chemistry is versatile and capable of high loading. With these advantageous factors, this proof of concept of selective multiple triggered releases from gold nanorods have a great potential as a new strategy for multiple controlled released application.
