Freeze-dried fruits and vegetables "inspired" Zhejiang University researchers to find new cancer treatments. Researchers use freeze-drying technology to turn body tissue into active biological materials, and then load drugs to exert therapeutic effects.

Researchers will freeze-dry lymph nodes taken out from the body to effectively retain their porous structure and a large number of active ingredients, and use them as a medium to store and deliver anti-tumor cell drugs to achieve more effective and lasting treatment.
