The wide field of applications for the treatment of biomolecular compounds is connected to research on low temperature plasma physics. Some keywords are:
•radiotherapy involving targeted nanoparticless
• ion beam studies of radiation damage in DNA
• protein formation in ice
•the effect of plasma produced radicals on cells and tissue
•plasmas in liquid
As an example you can observe the difference between non treated and plasma treated connective tissue. The untreated tissue does not show any changes to its structure while the treated cells don't behave like connective tissue anymore, they loose their inter cellular connection and behave like single cells. This process is reversible, which means that cells start to reconnect after a certian period of time.
