Dr. Lifeng Dong, associate professor in the department of physics, astronomy and materials science at Missouri State University, recently had two research articles published in the Journal of Nanotechnology. They are titled “Antimicrobial Activity of Single-Walled Carbon Nanotubes Suspended in Different Surfactants” and “Uptake of Single-Walled Carbon Nanotubes Conjugated with DNA by Microvascular Endothelial Cells.”

“Our findings reported in these two publications indicate that low toxicity to humans and high antibiotic effects make nanotubes serve as potential drug and gene vehicles for therapeutic applications,” said Dong. “They may also solve problems surrounding drug-resistant and multi-drug-resistant bacterial strains.”

Collaborators on the first article include Dr. Christopher Field, professor in the department of biomedical sciences, and Alex Henderson, a student from Truman State University. Those for the second article include student Joseph Harvey and Dr. Jianjie Wang from the department of biomedical sciences, and Dr. Kyoungtae Kim and student Jacob Hayden from the biology department. The research projects are supported in part by the Research Corporation for Science Advancement and the National Science Foundation.
