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–C bonds also increased after reparative reduction, indicating the restoration of graphene’s aromatic structure.

Surface photocurrent measurements reveal that the electronic interaction between Mn and TiO2, in which Mn serves as an electron acceptor and effectively inhibits the charge recombination in TiO2, results in a highly efficient photocatalytic activity for the degradation of rhodamine B under visible-light irradiation (λ > 420 nm).

Bi@Bi2O3 microspheres have been synthesized via a microwave- assisted solvothermal route without adding any surfactants. The degradation of rhodamine B and methyl orange reached ~96.6% and 100%, respectively, after 4 h reaction in the presence of the as-synthesized Bi@Bi2O3 microspheres.
