Drug sponge’ printed to reduce chemotherapy side effects

A sponge, capable of absorbing residual drugs delivered via catheter to treat cancer, has been 3D printed in an effort to reduce the side effects experienced by patients receiving chemotherapy. Researchers from University of California, Berkeley (CA, USA) have 3D printed a sponge capable of absorbing residual drugs following the administration of chemotherapy drugs via a catheter. The sponge is made from absorbent polymer coating a cylinder that is reportedly 3D printed to fit precisely in a vein that carries the blood flowing out of the target organ. For example, it may be printed to exactly fit into the patient's...
