Aim: To investigate Prussian blue nanoparticles (PBNPs) coated with the synthetic analog of dsRNA

polyinosinic-polycytidylic acid (polyIC) for their ability to function as HIV latency reversing agents.

Methods: A layer-by-layer method was used to synthesize polyIC-coated PBNPs (polyIC-PBNPs). PolyICPBNPs

were stable and monodisperse, maintained the native absorbance properties of both polyIC and

PBNPs and were obtained with high nanoparticle collection yield and polyIC attachment efficiencies.

Results: PolyIC-PBNPs were more effective in reactivating latent HIV than free polyIC in a cell model of

HIV latency. Furthermore, polyIC-PBNPs were more effective in promoting immune activation than free

polyIC in CD4 and CD8 T cells. Conclusion: PBNPs function as efficient carriers of nucleic acids to directly

reverse HIV latency and enhance immune activation.
