Scientists invent a smarter way to deliver chemotherapy with fewer side effects

Scientists at Far Eastern Federal University (FEFU) have created a new material designed to improve chemotherapy treatment. The innovation targets cancer cells more precisely, reducing harm to healthy tissue. This could make treatment less toxic and easier for patients to endure. Chemotherapy often damages both cancerous and healthy cells, leading to severe side effects. A common drug, 5-fluorouracil, leaves the body too quickly, forcing doctors to use high doses that worsen these effects.

The FEFU team developed a carrier made from a biocompatible two-component material mixed with tiny magnetic nanoparticles. Its porous, sponge-like structure holds the drug and releases it slowly over time. This gradual release means lower doses and fewer side effects. The magnetic particles serve two key purposes. They allow doctors to track the drug’s movement in real-time and control its release. When heated, these particles can also enhance the treatment’s effectiveness. The material is safe for humans and dissolves naturally in the body without causing harm. Researchers can also adjust the carrier’s properties for different treatments, moving closer to personalised cancer care.

This new carrier system could change how chemotherapy is delivered. By reducing toxicity and improving precision, it may help patients handle treatment better. The technology also opens doors for more tailored cancer therapies in the future.
