Tumor extracellular acidity, commonly reported within an approximate pH range of 6.5-7.1, contributes to invasion, immune suppression, and treatment resistance while also providing a recurrent, although nonexclusive, stimulus for responsive nanoplatform design. This narrative review critically examines pH-sensitive nanoplatforms that function as molecular switches by altering their structure, surface charge, assembly state, or payload accessibility under acidic conditions. The principal chemical strategies include acid-labile bond cleavage, pH-induced charge reversal, conformational gatekeeping, and ultra-pH-sensitive polymeric probes. Their radiotherapy-specific effects depend on the associated payload or inorganic component and may include increased tumor retention of high-Z materials, catalytic reactive oxygen species amplification, enhanced DNA damage, ferroptosis, cGAS-STING-mediated immune activation, and improved oxygen availability. The strength of evidence varies substantially among applications. Direct preclinical radiosensitization has been demonstrated for selected acid-triggered metal and gold nanoparticle systems, whereas many linker-based, nucleic-acid-gated, ferroptosis-inducing, and oxygen-delivering platforms remain supported mainly by complementary mechanistic studies or non-radiotherapy evidence. Nanoparticle-based radionuclide delivery and dual-responsive systems have also been investigated preclinically, although direct evidence for pH-gated renal sparing remains limited. The integration of pH-sensitive nanoplatforms with FLASH radiotherapy remains a conceptual and computationally informed direction without direct clinical validation. Beyond radiosensitization, pH-responsive gastrointestinal formulations have shown normal-tissue radioprotection in animal models, but tumor-selective reverse-switch nanoradioshields remain largely conceptual. Theranostic integration with MRI-CEST, acidity-sensitive PET, or Cherenkov-based sensing may support future image-guided treatment adaptation, but pH-informed dose painting has not yet been clinically validated. Clinical translation is further constrained by intratumoral pH heterogeneity, potential activation in inflammatory or ischemic tissues, protein-corona effects, manufacturing variability, uncertain pharmacokinetics, regulatory complexity, and the need to synchronize nanoparticle activation with irradiation. Progress will require compartment-specific switching, matched nonresponsive controls, patient-selection biomarkers, scalable manufacturing, and prospective demonstration of improved tumor control without unacceptable normal-tissue toxicity.</p>","PeriodicalId":11148,"journal":{"name":"Discover.
