Chinese researchers from Fudan University have developed a self-charging saline battery that is implanted under the skin and helps kill tumor cells by regulating the environment that promotes
As reported by Ukrinform, Xinhua reported it.
In studies on mice, the developed device was shown to selectively kill hypoxic cells by activating the antitumor effect of tirapazamine by creating oxygen-deficient conditions in tumors.
When battery and tirapazamine were used together, tumor volume decreased by an average of 90% within two weeks, and the tumor disappeared completely in four out of five mice.
The battery itself consists of biocompatible polyamide based on carbonyl and metallic zinc.
In addition, the battery can generate a discharge and self-charge cycle for continuous oxygen consumption in mouse tumors, thereby regulating tumor oxygen content and pH (hydrogen indicator).
University professor and co-author Xia Yunyao said, “This study is a cross between battery technology and biotherapy, which not only provides a new method of anticancer treatment, but also sets a precedent for the use of batteries in medicine.” Said.
As reported by Ukrinform, researchers from the Kunming Botanical Institute of the Chinese Academy of Sciences have developed an adhesive to heal wounds caused by snail mucus.
