A science paper published in MaterialsToday Chemistry reveals that cell phone signals can be used to release biological or chemical payloads from graphene oxide that's introduced into the human body. The paper, published in September of 2022, is entitled, "Remotely controlled electro-responsive on-demand nanotherapy based on amine-modified graphene oxide for synergistic dual drug delivery." The study abstract reveals how a cell phone can emit signals to activate a low voltag
