Researchers Develop Advanced Nose-to-Brain Drug Delivery Systems Using Nanotechnology
Researchers have made significant advancements in the field of drug delivery systems by utilizing nanotechnology and synthetic biology to create autonomous intranasal delivery systems. These systems are designed to overcome the physiological barriers of the nasal cavity, which traditionally hinder effective drug delivery to the brain. The study, published in Experimental & Molecular Medicine, highlights the use of three programmable vector types that actively target the olfactory epithelium, facilitating sustained drug release to the brain. The blood-brain barrier poses a significant challenge for central nervous system drug delivery, but intranasal administration offers a non-invasive alternative by bypassing this barrier through the olfactory and trigeminal nerve pathways. Despite the potential, the anatomical constraints of the nasal cavity, such as limited surface area and rapid mucociliary clearance, present challenges. The research explores various delivery systems, including synthetic nanoparticles,...
