Over the years, abuse of antibiotics has increased, leading to their presence in environment. Therefore, a sustainable method for detecting these substances is crucial. Researchers have explored biomass-based carbon dots (CDs) detect various contaminants, due low cost, environmental friendliness, and support circular economy. In our study, we reported synthesis CDs using pinecones (PCs) pinebark (PB) through microwave method. We characterized PCCDs PBCDs X-ray diffraction, Raman spectroscopy, Transmission Electron Microscope, Fourier transform infrared, Ultraviolet-visible, photoluminescence (PL) spectroscopy. The were tested detection amoxicillin (AMX) tetracycline (TC). results indicated that sizes 19.2 nm 18.39 nm, respectively, confirmed 002 plane graphitic structure. They exhibited excitation wavelength dependence, good stability, quantum yields ranging from 6% 11%. demonstrated “turn-off” TC AMX. limits (LOD) across broader concentration range found be 0.062 µM 0.2237 PBCDs. For AMX detection, presented an LOD 0.49 µM.
