Özet
Larval secretions of Lucilia sericata are rich in diverse proteins and bioactive constituents that exhibit potential interactions with metal-oxide interfaces, indicating their suitability for biologically driven nanoparticle surface engineering. In this work, these secretions were utilized as a natural surface modifier to alter the interfacial characteristics of ZnO nanoparticles. The extent of protein immobilization on the nanoparticle surface was determined using Bradford and BCA protein quantification methods. Structural and compositional evidence of surface modification was further obtained through scanning electron microscopy, Fourier-transform infrared spectroscopy, and energy-dispersive X-ray spectroscopy. Changes in colloidal stability induced by biomolecular adsorption were assessed via zeta potential measurements and determination of the point of zero charge (pHpzc). Following functionalization, ZnO nanoparticles exhibited a shift in surface charge from positive values toward a mildly negative regime, accompanied by a reduction in pHpzc. These observations suggest the incorporation of protein-derived acidic functional groups and the formation of a stable organic coating layer on the nanoparticle surface. Collectively, the findings indicate that larval secretion can serve as an effective and eco-compatible biointerface modifier, enabling controlled tuning of metal-oxide surface properties. This bio-derived functionalization strategy further underscores the potential of insect-based biomolecules as versatile tools in nanomaterials design, interfacial chemistry, and environmentally oriented nanotechnology applications.
