The blood-brain barrier (BBB) restricts the access of therapeutic agents to brain, complicating treatment neurological diseases, such as Alzheimer's disease (AD), Parkinson's (PD), multiple sclerosis (MS), glioma, etc. To overcome this limitation and improve drug delivery central nervous system (CNS), potential nanocarriers, including lipid-based nanosystems, has been explored. Through active targeting, surface nanocarriers can be modified with ligands that interact BBB, enhancing their uptake penetration across brain endothelium by different physiological mechanisms, receptor- or transporter-mediated transcytosis. This review seeks provide an overview targeting in delivery, while highlighting functionalized lipid treat diseases. Therefore, first sections, we discuss importance CNS present commonly used for functionalization, well summarize state art most recent relevant studies surface-modified nanosystems developed disorders. Lastly, challenges hindering clinical translation are discussed, critical insights future perspectives outlined. Although some limitations have identified, it is expected upcoming years these will established approach.
