Surgical excision of metastases is crucial for treating peritoneal carcinomatosis, and the success of this procedure largely depends on completely removing the tumor; researchers are exploring the use of novel fluorescent probes to enhance surgical outcomes.
In this study, ultrasmall porous silica nanoparticles (UPSN) were developed and tested in mice with colorectal and pancreatic cancers, demonstrating effective tumor targeting and imaging capabilities during surgery.
Results showed that the UPSN, particularly with Cy5 dye, provided superior tumor visibility and safety compared to existing imaging agents, indicating their potential as a valuable tool for improving the precision of tumor resections.
