Chinese scientists use nanoplatform ‘aircraft carrier’ to release drugs and attack tumours in cancer patients

like a microscopic aircraft carrier by finding tumour cells and releasing medicine to attack them.

Conventional treatments cannot completely eradicate cancer cells and they may damage normal tissue. A main reason for the failure of cancer treatment is the extensive metastasis of the disease through the patient’s blood and lymphatic vessels. The team built its “aircraft carrier” based on a polymer that resembles a tree’s branches and has a controllable shape and size and good biocompatibility. Using the polymer as a deck, the Donghua University researchers mounted other particles as “weapons” onto the carrier.

While CuS and DMXAA kill tumour cells in their own way, jointly they trigger the body’s immune system to fight the cancer by inducing immunogenic cell death and regulating immune responses.
