Proof of sandwiched graphene-membrane superstructure opens up a membrane-specific drug delivery mode

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Tsinghua University (THU) report a sandwiched superstructure for graphene oxide (GO) that transports through cell membranes. The discovery, published in Science Advances, opens up a membrane-specific drug delivery mode, which could significantly improve cytotoxicity effects over traditional drug carriers.
