The polymer films provided a cloak of invisibility for the implants, keeping the immune system from attacking, Chow said.
The nanomaterial technology serves as a non-invasive and biocompatible platform for the delivery of a broad range of therapeutics, said Dean Ho, an assistant professor of biomedical and mechanical engineering with the McCormick School of Engineering and Applied Science, a member of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University and the studys senior author.
The technology also may prove to be an effective approach for delivering multiple drugs, controlling the sequence of multi-drug delivery strategies and enhancing the life spans of commonly implanted devises such as cardiac stents, pacemakers and continuous glucose monitors.
For chemotherapy, this system could enhance treatment efficacy while preventing uncontrolled delivery and the resultant patient side effects, Ho said. Furthermore, as implantable devices continue to find widespread application in cardiovascular medicine, neural disorders and diabetes, the nano-cloaking capabilities can serve as a widely applicable approach to enhance the lifetime of these devices. This would eliminate unnecessary surgeries and enhance the efficiency of patient care.
Many cancer drugs, chemotherapies for example, are delivered systemically through the blood stream. The drugs attack cancer cells, but also other fast growing cells causing side effects s
