Microencapsulation of bioactive compounds in lipid carriers, such as liposomes, in addition to improving stability during storage by increasing bioavailability and controlled release, increases the efficiency of these compounds in vivo. The studies conducted on Padina algae show the existence of a high level of phenolic and antimicrobial compounds. Also, this alga has a significant amount of polyphenols with antioxidant and anti-AChE (acetylcholinesterase) properties, which can be used as a supplement to improve neurological disorders. Therefore, the purpose of this research was to produce and investigate the structural properties of nanoliposomes containing Padina algae extract using the heating method. The particle size of nanoliposomes produced at varying levels of lecithin and loaded extract was obtained in the range between 318 and 60 nm. The resulting values ​​for the polydispersity index and zeta potential indicate the uniformity of the produced particles along with the high electrostatic repulsion between the particles. The ability to load liposome particles at the lowest level of wall substance and the highest concentration level of the extract reached 52.8±0.3% in this research. Evaluation of the morphological characteristics of the structure using a transmission electron microscope shows the formation of uniform particles with a spherical geometry. The results of this research show the ability to produce a liposome structure containing Padina algae extract with suitable structural properties. These results can improve the prospect of possible use of this extract with a therapeutic approach.
