Graphical Abstract

Supramolecularly engineered chemiluminescence reporters (PCCS), consisting of L-serine-modified PLGA-encapsulated peroxyoxalate, chlorin e6 and superoxide dismutase, are reported. The PCCS reporters were applied for the simultaneous diagnosis and treatment of acute kidney injury.

Abstract

We report the “water-in-oil-in-water” preparation of kidney injury molecule-1-targeting supramolecular chemiluminescence (CL) reporters (PCCS), consisting of L-serine-modified poly(lactic-co-glycolic) acid (PLGA)-encapsulated peroxyoxalate (CPPO), chlorin e6 (Ce6) and superoxide dismutase (SOD), for early diagnosis and amelioration of acute kidney injury (AKI). In this system, O2, a biomarker of AKI, triggers the oxidation of CPPO to 1,2-dioxetanedione and subsequent CL emission via CL resonance energy transfer to Ce6. The L-serine-modified PLGA stabilizes CPPO and Ce6 via noncovalent interactions, promoting long-lived CL (half-lives: ≈1000 s). Transcriptomics analysis shows that PCCS reporters reduce the inflammatory response through glutathione metabolism and inhibition of the tumor necrosis factor signaling pathway. The reporters are able to non-invasively detect AKI at least 12 h earlier than current assays, and their antioxidant properties allow simultaneous treatment of AKI.
