    Researchers at the University of British Columbia, Canada, have successfully developed a magnetic drug delivery implant with a diameter of only 6 mm, using silicon sponge and carboxy iron particles, providing a new drug choice for patients who need a large number of drugs or intravenous injection every day, the website of the University of British Columbia announced recently Relevant research was published online in the Journal of advanced functional materials The device is made by wrapping the silicon-based sponge and magnetic carboxyl iron particles into the polymer layer After the drug is injected into the device, it is transplanted to the part to be treated by surgery, and the magnetic activation device is applied to the patient's skin, the sponge in the device will be deformed, forming a tiny mouth, so as to release the drug to the surrounding tissues The dosage can be adjusted by applying different magnetic field intensity The researchers used docetaxel, a prostate cancer drug, to test the new device in laboratory animal tissues The results showed that the device could still be administered as needed after repeated use Compared with the control group, the device showed the effect of reducing cancer cells, which proved the effectiveness of this way of administration The team will then improve the design of the implant and test its feasibility in vivo models in the next few years.
