2013 conference paper
On our way to understand sterilization mechanisms — Inactivation and modification of bio-macromolecules by H<inf>2</inf> and O<inf>2</inf> plasma
2013 Abstracts IEEE International Conference on Plasma Science (ICOPS).
TL;DR:
Investigation of the impact of H2 and O2 plasma on bio-macromolecules reveals that oxygen plasma leads to a higher inactivation than hydrogen plasma, and SDS PAGE indicates that neither fragmentation nor unfolding occurs.

2013 journal article
Utilization of Low-Pressure Plasma to Inactivate Bacterial Spores on Stainless Steel Screws
ASTROBIOLOGY, 13(7), 597–606.
Contributors: * , M. Fiebrandt*, M. Raguse*, P. Awakowicz*, G. Reitz* & R. Moeller *
author keywords: Bacillus spores; Contamination; Spacecraft hardware; Plasma sterilization; Planetary protection
MeSH headings : Bacillus / physiology; Microscopy, Electron, Scanning; Plasma Gases; Spores, Bacterial; Stainless Steel
TL;DR:
The use of low-pressure plasma with an additional treatment of evaporated hydrogen peroxide led to an enhanced spore inactivation that surpassed either single treatment when applied alone, which indicates the potential application of this method as a fast and suitable way to reduce spore-contaminated spacecraft hardware components for planetary protection purposes.
