Bioengineered hybrid dual-targeting nanoparticles reprogram the tumour microenvironment for deep glioblastoma photodynamic therapy.

ABSTRACT: Glioblastoma (GBM) poses significant therapeutic challenges due to its hypoxic and immunosuppressive tumour microenvironment (TME), low immunogenicity and physical barriers. While combining photodynamic therapy (PDT) with immunotherapy holds promise, its efficacy is hampered by insufficient immune activation. In this study, we develop a multifunctional photodynamic-enhanced biomimetic intelligent nanoplatform (FBFO@HM@aOPN) responsive to the TME. The nanoplatform consists of a dual-enzyme nanozyme encapsulated in a prokaryotic-eukaryotic hybrid membrane, further modified with a pH-sensitive tumor-targeting antibody. After systemic administration, FBFO@HM@aOPN selectively accumulates in the GBM through vascular regulation and extracellular matrix (ECM) remodelling while generating oxygen to
