Abstract: BACKGROUND: In recent years, chiral mesoporous silica nanoparticle gradually becomes widely studied drug carriers. With which properties does it have unique drug delivery advantages?
OBJECTIVE: To explore the key parameters that chiral mesoporous silica nanoparticles play a dominant role in drug delivery systems. 
METHODS: Starting from the synthesis, molding mechanism, chiral properties, drug-carrying release properties and biosafety of chiral mesoporous silica nanoparticles, PubMed and CNKI were used to retrieve articles published from 1990 to 2022. All articles were initially screened according to the inclusion and exclusion criteria, and 49 articles with higher relevance were retained for review. 
RESULTS AND CONCLUSION: In addition to the template being an important condition for the synthesis of chiral mesoporous silica nanoparticles, the surfactant, reaction temperature, pH, stirring speed, chain length of the surfactant, anions and cations and other factors also affect the structure of the synthetic materials. In the application as drug carriers, chiral mesoporous silica nanoparticles have more advantages in drug loading and delivery due to their twisted pores, such as the high pore network structure of chiral mesoporous silica nanoparticles can increase the drug loading. In general, the larger the specific surface area and pore volume of chiral mesoporous silica nanoparticles, the higher the drug loading. The pore size of chiral mesoporous silica nanoparticles can inhibit the crystal structure of drugs, and effectively change the drug crystal form to amorphous, thus significantly improving the bioavailability of drugs. How to accurately design chiral mesoporous silica nanoparticles with chiral morphology, chiral structure or molecular chirality according to drug application needs is a key problem realizing the application value of this carrier, which needs more investigation. 

Key words: chiral mesoporous silica nanoparticle, drug delivery, poorly water-soluble drug, biocompatibility, biodegradability, cytotoxicity, bioavailability, surfactant
