Microfluidic fabrication of plasmonic microcapsules

摘要: This paper presents the plasmonic microcapsules with well-ordered nanoparticles embedded in polymer network fabricated by using a microfluidic device. The nanoparticle arrays on microcapsule form high-density uniform “hot-spots” deposited metal film, which localized surface plasmon resonance effect is obtained. These can be engineered and modified size film thickness. Repeatable Surfaced-Enhanced Raman Scattering (SERS) has been obtained highest analytical enhancement factor of 107 being achieved.
