New design improves water decontamination via plasma jet

Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially ...

How bacteria defend themselves against plasmas

Plasmas are used in wound treatment against pathogens that are resistant to antibiotics. However, bacteria can defend themselves. They employ a heat shock protein that protects them.

Tiny beads preserve enzymes for biocatalysis

Plasmas can provide the co-substrate needed for biocatalysis of valuable substances, but they are also harmful to enzymes. By attaching enzymes to small beads, the enzymes are protected and remain active up to 44 times longer.

Using plasma against toxic PFAS chemicals

Harmful PFAS chemicals can now be detected in many soils and bodies of water. Removing them using conventional filter techniques is costly and almost infeasible. Researchers at the Fraunhofer Institute for Interfacial Engineering ...

Understanding the utility of plasmas for medical applications

Plasma medicine is an emerging field, as plasmas show promise for use in a wide range of therapies from wound healing to cancer treatment. Plasma jets are the main plasma sources typically used in plasma-surface applications. ...

Study finds salt nanoparticles are toxic to cancer cells

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles—more commonly known as salt—are toxic to cancer cells and ...
