Nanoparticles for drug delivery to the brain particles until the desired consistency is acquired. This manufacturing process is already scaled and in use in the food industry, which therefore makes it more appealing for researchers and for the drug delivery industry. Liposomes can also be functionalized by attaching various ligands on the surface to enhance brain-targeted delivery. Another type of lipid-nanoparticle that can be used for drug delivery to the brain is a cationic liposome. These are lipid molecules that are positively charged. One example of cationic liposomes uses bolaamphiphiles, which contain hydrophilic groups surrounding a hydrophobic chain to strengthen the boundary of the nano-vesicle containing the
