Drexel Scientists Examine Uses of Nanodiamonds in Nature Nanotechnology

A team of researchers who specialize in nanotechnology, led by Dr. Yury Gogotsi, director of the A.J. Drexel Nanotechnology Institute, offered a review of nanodiamond research, in the December 18 edition of Nature Nanotechnology to sift through new ways scientists are using these tiny treasures. ...


Nearly 50 years ago scientists discovered that detonating powerful explosives had the ability to create, not just destroy. Nanodiamonds, diamond-structured particles measuring less than 10 nanometers in diameter, which are the resultant residue from a TNT or Hexogen explosion in a contained space, are now being studied in a variety of science, technology and health applications. A team of researchers who specialize in nanotechnology, led by Dr. Yury Gogotsi, director of the A.J. Drexel Nanotechnology Institute, offered a review of nanodiamond research, in the December 18 edition of Nature Nanotechnology to sift through new ways scientists are using these tiny treasures.

The authors, who also include Dr. Vadym Mochalin, assistant research professor of materials science at Drexel, Dr. Olga Shenderova senior scientist and head of the Nanodiamond Laboratory at the International Technology Center (ITC) and Dr. Dean Ho, associate professor of biomedical and mechanical engineering at Northwestern University, survey a rapidly growing field of fundamental and applied research as well as technological development surrounding nanodiamonds.
“We examine the importance of nanodiamond in biomedical, optical, composites, lubricants and other applications,” Gogosti said. “The success of nanodiamond materials in biomedical applications stems from the fact that many small molecules such as proteins, antibodies, therapeutics and nucleic acids can bind to the surface of nanodiamonds, making it an ideal candidate for use in drug-delivery and surgical implants.”
According to the piece, nanodiamonds possess a unique combination of qualities, such as accessible surface area, versatile chemistry, chemical stability and biocompatibility. These traits, and the fact that nanodiamonds are non-toxic, make the particles ideal candidates for a variety of tasks including drug delivery cancer diagnostics, and mimicking proteins.
“Rich and very versatile surface chemistry, which can be and, actually, needs to be tailored for each particular application of nanodiamond, makes possible matching this material to a variety of environments, ranging from oil to water and polymers,” Mochalin said. “This is especially important when considering nanodiamond’s application in drug delivery and polymer composites for tissue engineering scaffolds.”
Specific uses mentioned in the group’s survey of the research include using nanodiamonds for targeted therapy and imaging, two applications essential to the treatment of cancer. The article notes that preliminary studies in mice have shown that drugs mediated with nanodiamond were able to reduce a tumor’s ability to resist the drug treatment.

MXene is one of the most sensitive gas sensors ever reported

MXene gas sensorsMXene is one of the most sensitive gas sensors ever reported that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person’s breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best “chemical noses” even more sensitive.

Partial breaking of the Coulombic ordering of ionic liquids confined in carbon nanopores

An international team of researchers, including Drexel's Yury Gogotsi, PhD, observed that ions will forgo their typical alternating charge ordering when they are forced to jam into a small, sub-nanometer-sized, space — a behavior modification not unlike people relinquishing personal space in order to pack into a crowded subway car. The discovery could lead to safer energy storage devices and better water filtration membranes.In their most recent paper in Nature Materials researcher from Drexel University led by prof. Yury Gogotsi showed that Coulombic ordering reduces when the pores can accommodate only a single layer of ions. The non-Coulombic ordering is further enhanced in the presence of an applied electric potential.
