Chinese Scientists Develop Magnetically Controlled Diatom-Derived Microrobots for Glioblastoma Treatment
Researchers from the Shenyang Institute of Automation and Shengjing Hospital in China have developed magnetically controlled microrobots derived from diatoms for targeted glioblastoma treatment through photodynamic therapy. These microrobots utilize the natural chlorophyll from diatoms to induce cytotoxicity in cancer cells without external drugs. Preclinical trials demonstrated significant reduction in glioblastoma cell viability, with minimal toxicity, highlighting a promising direction for future cancer therapies.

Scientists in China have engineered magnetically controlled microrobots from diatoms for treating glioblastoma via photodynamic therapy (PDT). The microrobots leverage natural chlorophyll for photosensitization, eliminating the need for drug loading.
Developed by the Shenyang Institute of Automation and Shengjing Hospital, these microrobots utilize the porous silica structures of diatoms, which enhance light penetration and allow for precise navigation using AI algorithms. Preclinical trials showed a reduction in glioblastoma cell viability to 19.5% with minimal toxicity. The technology offers a drug-free approach to target brain tumors, presenting a significant advancement in cancer treatment.
