Protein Inactivation by Low‐temperature Atmospheric Pressure Plasma in Aqueous Solution
Abstract
Plasma medicine is an attractive new research area, but fundamental information related to plasma modification of biomacromolecules in aqueous solution remains elusive. As described herein, we investigated the chemical effects of low‐temperature atmospheric pressure plasma on protein in aqueous solution using lysozyme as a model. Plasma treatment decreased enzymatic activity and changed the secondary structure that results from the increased molecular weight of lysozyme with chemical modification. These effects arise neither from UV light nor from plasma heat, suggesting that the reactive species generated by the plasma affect lysozyme. The information presented in this paper represents a crucial first step for elucidating chemical reactions induced by plasma on proteins for biomedical applications.magnified image

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
