Inflammatory bowel disease (IBD) causes inflammation to the gastrointestinal tract. Local administration of anti‐inflammatory drugs such as 5‐aminosalicylic acid (5‐ASA) can alleviate the symptoms of IBD. The application of nanoparticles for IBD treatment in direct rectal administration showed high drug availability and treatment efficacy. However, relying on size‐dependent adsorption of smaller particles is not sufficient for making the formulation capable of targeting. Intestinal organoids can improve the functionality of the nanoparticles due to their ability to adsorb small nanoparticle inside the lumen and attach to the damaged area. In this study, intestinal organoids were used as carriers of 5‐ASA‐loaded poly(lactic‐ co ‐glycolic acid) nanoparticles. The nanoparticle sizes, confirmed by scanning electron microscopy, were 200–300 nm and the zeta potential were negative. The nanoparticles did not have any noticeable pernicious effect on organoid growth and viability. After mixing the nanoparticles with Matrigel and organoids, Rhodamine B loaded inside the nanoparticles was highly detected inside the organoid's lumen after 3 days by confocal fluorescent microscopy and no longer detected in the lumen after day 4. It may be attributed to the ability of the lumen to digest particles. Thus, the organoid Trojan horse system is a possible approach for delivering drugs to inflamed areas. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 876–886, 2018.
