摘要：

The action of low-pressure inductively coupled plasma discharge on selected homo-polypeptides of amino acids, i.e., fundamental building blocks of proteins, has been investigated in order to evaluate their removal rates under different treatment conditions. It has been found that the removal rates of the homo-polypeptides studied are strongly linked to the composition of the plasma discharges, but they are almost insensitive to their chemical composition. This provides an indication that all proteins could be removed at similar rates by a given plasma discharge, which is a finding of paramount importance mainly with respect to decontamination of surfaces and elimination of infectious proteins like prions.
