MIT researchers developed a manufacturing technique that rapidly generates large quantities of nanoparticles coated with drug-delivering polymers, which hold great potential for treating cancer. The particles can be targeted directly to tumors, where they release their payload while avoiding many of the side effects of traditional chemotherapy.

Here, researchers from Nanjing University of Aeronautics and Astronautics propose to control thermal stress at coating interfaces during laser induction processes and demonstrate a novel process for precisely graphenizing ultra-thin diamond coating surface through laser induction and mechanical cleavage, without damaging the substrates.

Their work provides an effective and cost-efficient avenue to overcome application bottlenecks in engineered diamond surfaces, expanding their use in friction pairs such as cutting tools, bearings, and mechanical seals. Moreover, it may facilitate advancements in multicarbon heterostructures and their preparation methods, supporting potential applications in electronics, aviation, and biomedicine involving diamond, graphene, and all-carbon devices.
