A highly selective iron oxide-based imaging nanoparticle for long-term monitoring of drug-induced tumor cell apoptosis

PSA was conjugated onto IONP by first covalently linking Neu onto a 10 nm IONP core and then attaching PSA to neu via biotin–avidin interaction. When applied in vivo, IONP-Neu-PSA-Cy5.5 produced persistent near-IR signal specifically for monitoring tumor apoptosis.

Peptide assembly assisted triplet–triplet annihilation photon upconversion in non-deoxygenated water

Peptide-tuned TTA-UC luminescence is reported by the formation of UC chromophore-assembled tetrahedral nanorods. Intense UC emission from the upconversion donor to acceptor in nanorods can be observed in non-deoxygenated water.

About this collection

A collection of original research and reviews focussing on Biomaterials for Imaging and Sensing. The goal of this collection is to highlight the most exciting advances in responsive materials, as applied to real-time analysis of analytes relevant to life sciences including proteins, electrolytes and cells. Both in vivo and in vitro measurements were welcome. Here, we define biomaterials broadly including any number of soft or hard materials including plasmonic materials, polymeric systems, self-condensing approaches, biomimicry etc.
