Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress. In two new publications in the journal Molecular Therapy, University of Cincinnati (UC) biomedical engineering professor Peixuan Guo,...

For years, RNA has seemed an elusive tool in nanotechnology research"”easily manipulated into a variety of structures, yet susceptible to quick destruction when confronted with a commonly found enzyme. "The enzyme RNase cuts RNA randomly into small pieces, very efficiently and within minutes," explains Peixuan Guo, PhD, Dane and Mary Louise Miller Endowed Chair and professor of biomedical engineering at the University of Cincinnati (UC). "Moreover, RNase is present everywhere, making...

Using an RNA-powered nanomotor, University of Cincinnati (UC) biomedical engineering researchers have successfully developed an artificial pore able to transmit nanoscale material through a membrane. In a study led by UC biomedical engineering professor Peixuan Guo, PhD, members of the UC team inserted the modified core of a nanomotor, a microscopic biological machine, into a lipid membrane. The resulting channel enabled them to move both single- and double-stranded DNA through the membrane....


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
