Nanoparticles-based delivery system and its potentials in treating central nervous system disorders

Area of Science:

• Neuroscience
• Biomedical Engineering
• Materials Science

Background:

• Central nervous system (CNS) disorders, including Alzheimer's and Parkinson's diseases, pose significant global health challenges.
• The blood-brain barrier (BBB) restricts the entry of therapeutic agents into the brain, complicating treatment strategies.
• Nanoparticles offer unique physicochemical properties, such as small size and morphology, for effective drug delivery across the BBB.

Purpose of the Study:

• To review recent advancements in nanoparticle-based drug delivery systems for CNS disorders.
• To discuss conventional and innovative nanocarrier systems designed for brain delivery.
• To explore the prerequisites, limitations, and challenges associated with using nanocarriers for CNS delivery.

Main Methods:

• Literature review of nanoparticles for CNS drug delivery.
• Analysis of nanoparticle properties (size, morphology, functionalization) for BBB penetration.
• Discussion of controlled drug release and targeting capabilities of functionalized nanomaterials.

Main Results:

• Nanoparticles demonstrate potential in overcoming the BBB due to their inherent properties.
• Functionalization of nanomaterials enhances drug delivery by enabling controlled release and targeting.
• Various nanoparticle-based systems, both conventional and innovative, are being developed for CNS treatment.

Conclusions:

• Nanoparticles represent a promising strategy for enhancing drug delivery to the CNS.
• Addressing challenges like protein corona formation is crucial for optimizing nanocarrier efficacy.
