Abstract
En 中文
Inspired by natural cellular compartments, nanoreactors are spatially confined nanostructures that precisely regulate chemical and biological reactions and act as high-performance catalytic nanocontainers. Multifunctional integration of these systems surmounts the inherent limitations of conventional therapeutic modalities. This review focuses on recent breakthroughs in organic and organic–inorganic hybrid nanoreactors, highlighting three core effects: (1) the spatial confinement effect, which elevates the reactant concentration, accelerates mass transfer, lowers activation energy, modulates electronic states, and boosts reaction rates by orders of magnitude; (2) the synergistic effect of active sites, which enables efficient cascade reactions via spatially segregated or hierarchical catalytic architectures; (3) the stimuli-responsive effect, which dynamically controls catalysis and cargo release under endogenous (pH, enzymes, ROS) or exogenous (light, temperature) cues. Typical nanoreactors (liposomes, polymeric micelles/vesicles, mesoporous silica, protein cages, and organic–inorganic hybrids) are systematically discussed regarding structural merits and biomedical applications in treating diabetes, rheumatoid arthritis (RA), chronic wound healing, cancer, and Alzheimer's disease (AD). Current challenges and future perspectives are also addressed. Intelligent nanoreactors are expected to offer immense potential for disease diagnosis and therapy.
