SPN surface bifunctionalisation. a Schematic of the modification of the surface of SPN-multi-nanoparticles with biotin followed by DBCO-594, (i) 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysulfosuccinimide (sulfo-NHS). b PL spectra of the nanoparticle solutions with reactive and unreactive dye (red and black lines, respectively). Samples were pulsed at 450 nm, with 10 vol% THF added. c Images of lateral flow strips run with unreactive and reactive dye nanoparticle solutions alongside the solutions (with 10 vol% THF added) all irradiated with UV light (365 nm)
