In this study, fluorone reagents were immobilized in TEOS/APTES-based sol–gel silica matrices and their application as sorption–luminescent sensors was analyzed. The advantages and limitations of physical adsorption, ionic fixation, covalent binding, andimmobilization methods were compared. The structure of sol–gel matrices and the interactions of their functional groups withindicator molecules were examined. By encapsulating fluorone indicators, their selectivity, physicochemical properties, andanalytical signal stability were evaluated. The effects of pH, ionic strength, and interference factors on the detection of Al³⁺ andZn²⁺ ions were investigated, as well as selectivity issues for antibiotics (tetracyclines, sulfonamides, quinolones). The resultsdemonstrate that the TEOS/APTES system provides high flexibility but requires strict optimization, and it is shown to be apromising material for the development of optical sensors
