Some materials show promise promoting bone regeneration by enhancing its natural electrical properties, according to a review in the journal Science and Technology of Advanced Materials. [42] "Our nature-inspired approach enabled us to trick the kidney environment to let nanoparticles pass through," adds Dr. Melika Sarem who was a co-author of the study. [41] A group of researchers from ITMO University has come up with the concept of a new drug against cancer: a nanorobot made of DNA fragments, which can potentially be used not only to destroy cancer cells, but also to locate them in the body. [40] A team of researchers at the Hebrew University of Jerusalem in Israel has now made such cascades in the lab by encapsulating three enzymes and enzyme cofactors in nanoreactors made from metal-organic framework nanoparticles. [39] Researchers have developed a new form of nanoparticle and associated imaging technique that can detect multiple disease biomarkers, including those for breast cancer, found in deep-tissue in the body. [38] Researchers at University of Utah Health developed a proof-of-concept technology using nanoparticles that could offer a new approach for oral medications. [37] Using scanning tunneling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. [36] A fiber optic sensing system developed by researchers in China and Canada can peer inside supercapacitors and batteries to observe their state of charge. [35] The idea of using a sound wave in optical fibers initially came from the team's partner researchers at Bar-Ilan University in Israel. Joint research projects should follow. [34]
