Nano-conjugates of bovine pancreatic ribonuclease A (RNase) have been synthesized using in situ atom transfer radical polymerization (ATRP). Compared with native RNase, such nano-conjugates exhibited enhanced delivery efficiency, inhibitor resistance and cytotoxicity for cancer cells. This work provides a novel platform for delivery of therapeutic proteins for cancers therapeutics and other applications.

Reparative reduction of graphene oxide to obtain high-quality graphene films has been achieved by introducing carbon radicals during the thermal annealing process to eliminate lattice defects. Sheet conductivity of the reparatively reduced single-layer graphene films was significantly increased compared with thermally annealed films. The number of C每C bonds also increased after reparative reduction, indicating the restoration of graphene*s aromatic structure.
