Abstract: “CARBON QUANTUM NANODOTS DOPED HERBAL MOLECULES AS A POTENTIAL ANTI-BACTERIAL AGENTS” The present invention discloses a novel composition and method for enhancing poultry health and productivity by replacing conventional antibiotic growth promoters (AGPs) with carbon quantum dots (CQDs) doped with essential oils (EOs). This invention addresses the global challenge of antimicrobial resistance (AMR) resulting from the overuse of antibiotics in poultry farming. CQDs, synthesized via green pyrolysis of citric acid and ethylenediamine, are conjugated with EOs derived from thyme, cinnamon, tea tree, eucalyptus, oregano, citral, and mentha through a single-step acid reflux method. The resulting Nanobiotics™ exhibit potent antimicrobial activity against pathogenic bacteria, including E. coli, Salmonella typhimurium, and Clostridium perfringens, with demonstrated minimum inhibitory concentrations (MICs) and bactericidal effects. Characterization through UV-Vis spectroscopy, TEM, and DLS confirms the nanoscale structure (2–10 nm), biocompatibility, and stability of the CQD-EO conjugates. In vivo trials involving broiler chickens show improved feed conversion ratios (FCRs), weight gain, and modulation of the caecal microbiota, favoring beneficial bacteria such as Lactobacillus spp. while suppressing coliforms. The invention harnesses the synergistic antimicrobial, antioxidant, and anti-inflammatory properties of EOs, enhanced by the high surface reactivity and drug-carrier efficiency of CQDs. This innovation provides a sustainable, non-toxic alternative to AGPs, mitigating AMR risks while optimizing poultry growth and gut health. Applications extend to feed additives, veterinary therapeutics, and agricultural nanotechnology, meeting global demands for safer livestock practices.
