Low power upconverted near-IR light for efficient polymeric nanoparticle degradation and cargo release

Adv Mater. 2013 Jul 19;25(27):3733-8. doi: 10.1002/adma.201300902. Epub 2013 May 31.

Abstract

By encapsulating NaYF4 :Tm.Yb upconverting nanocrystals in UV-degradable polymer capsules, it is possible to access efficient polymer photodegradation and remotely controlled release using near-IR laser light at an unprecedentedly low power.

Keywords: light-degradable polymers; photo-induced degradation; photo-release; upconverting nanoparticles.
