The development of new antimalarial drugs is important for eliminating malaria. One of the strategies expected is the development of antisense oligonucleotides (ASOs) therapy which can be used specifically and targeted as a protein sinthesis inhibitor of P. falciparum such as EBA175 and DHS protein. To reach the mRNA target, ASOs need to be delivered by a delivery system that can protect enzymatic degradation and increase its permeability. This research formulated and characterized nanoparticles (NP) ASOs as a system used to deliver ASOs. The NP system used was cationic chitosan polymer with a combination of PLGA and poloxamer. The NP was prepared by precipitation method in which stirring rate and stirring time were optimized. From the experiments carried out, ASO NPs with particle size characteristics <200 nm, polydispersion index <0.5, positive zeta potential, and spherical morphology were produced from a NP formula prepared at stirring rate 900 rpm for 60 minutes.Antimalarial activities was performed by enzymatic LDH assay method. From the tests conducted, ASO NP showed inhibitory activity on the growth of P. falciparum.
