title: Assembling of a functional cyclodextrin-decorated upconversion luminescence nanoplatform for cysteine-sensing.
abstract: A novel rhodamine-oxaldehyde (RHO) functionalized β-NaYF4:Yb(3+)/Er(3+) upconversion nanoparticle (UCNP) for specific detection of cysteine (Cys) in aqueous solution was achieved through a Förster resonance energy transfer (FRET) process. Based on self-assembling interaction, hydrophobic upconversion nanoparticles could be modified with α-cyclodextrin to make them water dispersible.
