Chemical modification of native starch strengthened its hydrophobicity, as indicated by lower crystallinity in XRD analysis. The TGA validated the thermal stability of SANPs. Morphological investigation indicated a beehive-like structure with constant porosity changed to evenly dispersed spherical nanoparticles when Starch acetate is converted into SANPs. Dynamic light scattering measured the particle sizes of SANPs to be 161 nm. Drug encapsulation brought up the SANPs particle size to 249 nm. Isoniazid, Rifampicin, and Pyrazinamide exhibited 72 %, 83 %, and 75 % encapsulation efficiency at a 2:1 polymer-drug ratio, respectively. In phosphate-buffered saline (pH 7.4), drug release behavior exhibited 55 %, 30 %, and 45 % release of isoniazid, rifampicin, and pyrazinamide over 24 hours.

Among the biological contaminants, waterborne pathogens pose a significant threat to human well-being. Since nanoparticle-based biosensors have a higher sensitivity for detecting bacteria than conventional detection techniques, they have become increasingly prevalent. In this context, the current study reports zinc oxide nanoparticles functionalized with lysozyme (ZnO@LY NPs) via a modified oxidation-reduction mechanism, followed by an assessment of their antibacterial activity. The morphology and size of the functionalized ZnO@LY NPs were determined using Transmission electron microscopy-energy dispersive X-ray spectroscopy (TEM-EDX), X-ray diffraction (XRD), dynamic light Scattering (DLS), and zeta potential analysis, which revealed nanoparticles of size between 14 and 32 nm with + 31.1 mV charge. Further, the functionalization of ZnO with lysozyme was confirmed using Fourier-transform infrared spectroscopy (FTIR) and Ultraviolet-Visible (UV-Vis) spectroscopy. The antibacterial efficacy of ZnO@LY NPs and ZnO NPs against Gram-positive bacteria (<em>Staphylococcus aureus</em>) was assessed in a comparative study. After 30 min and 24 h of treatment with ZnO@LY NPs at 250 ppm, the agar spot assay revealed the absence of colonies. Similarly, ZnO@LY NPs exhibited a 25 % stronger and statistically significant antibacterial impact than non-functionalized ZnO NPs in the bacterial growth inhibition assay, as confirmed by repeated measures (RM)-ANOVA analysis. Moreover, Dunnett's multiple comparison test revealed that ZnO@LY NPs showed a dose-dependent linear response when compared to ZnO NPs. The superior antibacterial performance of ZnO@LY NPs is attributed to improved bacterial surface interactions, stability, and biocompatibility facilitated by lysozyme functionalization.
