Fluorescent-Tagged, pH- and Redox-Responsive Polymeric Nanocarrier for Site-Specific Gastrointestinal Delivery

), ensuring stability in dilute environments. Spherical nanocarriers remain stable under acidic conditions (∼pH 2.0) and disassemble at neutral to basic pH (∼pH 7.4), mimicking gastrointestinal conditions. This property allows site-specific, stimulus-triggered drug release, with high drug-loading efficiency. The stimuli-responsiveness of the nanocarrier not only enhances oral drug delivery but also offers a versatile platform for encapsulating a wide range of therapeutics and diagnostics. This multifunctional nanocarrier system opens new avenues for personalized medicine and advanced material technologies, highlighting its potential for broader translational and industrial applications.
