Publikováno v: Plasma Medicine. 3:97-114

The membrane of both proand eukaryotic cells is the cell’s interface with the environment. It is the first interaction site of any substance that is externally applied, including reactive species in the liquid cell environment created by plasma med

From RONS to ROS: Tailoring Plasma Jet Treatment of Skin Cells

Autor: Kai Masur, Jörn Winter, Kristian Wende, Klaus-Dieter Weltmann, H. Tresp, Stephan Reuter, Malte U. Hammer, Ansgar Schmidt-Bleker

Publikováno v: IEEE Transactions on Plasma Science. 40:2986-2993

Finding a solution for air species contamination of atmospheric pressure plasmas in plasma medical treatment is a major task for the new field of plasma medicine. Several approaches use complex climate chambers to control the surrounding atmosphere.

Controlling the Ambient Air Affected Reactive Species Composition in the Effluent of an Argon Plasma Jet

Autor: H. Tresp, Ansgar Schmidt-Bleker, Klaus-Dieter Weltmann, Jörn Winter, Stephan Reuter, Malte U. Hammer

Publikováno v: IEEE Transactions on Plasma Science. 40:2788-2794

The influence of ambient air species is an ever-present problem for atmospheric pressure plasma jet applications. In particular, applications where the plasma-induced effects are extremely sensitive to specific types of ambient species (oxygen, nitro

The Contribution of DOPA to Substrate-Peptide Adhesion and Internal Cohesion of Mussel-Inspired Synthetic Peptide Films

Autor: J. Herbert Waite, Jacob N. Israelachvili, Abril Estrada, Jing Yu, Malte U. Hammer, Travers H. Anderson

Publikováno v: Advanced Functional Materials. 20:4196-4205

Mussels use a variety of 3, 4-dihydroxyphenyl-l-alanine (DOPA) rich proteins specifically tailored to adhering to wet surfaces. Synthetic polypeptide analogues of adhesive mussel foot proteins (specifically mfp-3) are used to study the role of DOPA i

Publikováno v: Journal of Endotoxin Research. 11:167-173

Lipopolysaccharides (LPSs) play a dual role as target and as effector molecules. The knowledge of the LPS-induced activation of human immune cells is increasing; however, surprisingly, much less effort seems to be directed towards the understanding o
