    Abstract:
    In recent days, reported researches demonstrated that encapsulation of natural hydrophobic drug molecules (Piperine) into the biodegradable polymer system with nanoformulations opens a novel prospect in bio-nanomedicine field. Generally, the nanostructured materials embedded with the drug molecules could render enhanced efficiency in therapies. Piperine is a chief alkaloid compound of natural black pepper exhibits excellent anti-convulsant efficiency in the anti-epileptic treatment. Nonetheless, the poor water solubility of the piperine molecules has some difficulties in drug delivery and clinical applications. Herein we report the synthesis of Copper oxide quantum dots coated Hyaluronic acid (HA)/ Poly(lactic-co-glycolic acid) (PLGA) with for the effective delivery of piperine in the targeted drug delivery for epilepsy treatment. The physicochemical characterization was performed using the as prepared material. The crystal structure, surface morphology and the elemental composition were investigated from XRD, SEM, TEM and EDX analyses respectively. The surface morphology clearly stated the loading of CuO QDs loaded HA/PLGA microspheres. The capping of the polymer matrix was also studied using FTIR analysis. A Photoluminescence spectrum is also recorded. This study was illustrating that Piperine loaded CuQDs@HA/PLGA nanostructures exhibit improved neuroprotection and encourage the activation of astrocytes in chemical kindling model of epilepsy. This proposed material could be a novel and effective therapeutic platform for the targeted drug delivery systems.
