 This study investigated the potential use of synthetic calcium silicates and phosphates as carriers for targeted drug delivery for the effective treatment of cancerous tumors. It found that these compounds can be used to deliver chemotherapy agents to tumors while limiting their impact on healthy tissue. Additionally, the study showed that the release rate of the drug could be controlled by adjusting the amount of calcium silicate and phosphate present in the composite.
