Transcutaneous plasma stress: From soft-matter models to living tissues

Publication date: October 2019Source: Materials Science and Engineering: R: Reports, Volume 138Author(s): X. Lu, M. Keidar, M. Laroussi, E. Choi, E.J. Szili, K. OstrikovAbstractThis review critically examines the multiple effects of low-temperature, atmospheric pressure plasma stress on the “on top” (collectively termed cutaneous) materials, to reveal the effects of this stress on the materials that lay underneath, collectively termed sub-cutaneous materials. Plasma generated reactive agents presents stress and trigger relayed effects within the cutaneous layers, leading to transcutaneous penetration of the plasma-induced stress into sub-cutaneous materials. Among the many possibilities from the areas spanning soft matter and life sciences, the effects of reactive plasma agents help improve the outcomes of cutaneous wound healing, reduce skin cancer tumors, and eradicate biofilms on biomedical implant materials. Cutaneous materials include animal skin or laboratory models using soft matter such as liquid media, gels, and cell cultures. Here we examine permeable interfaces of cutaneous materials and sub-cutaneous living tissues subjected to low-temperature atmospheric-pressure plasmas as a multi-modal reactive system producing stress on materials through multiple reactive agents including radicals, excited atoms and molecules, ions, heat, UV, and electric fields. Interaction of plasma-radiative stress with cutaneous materials leads to the unexpected, yet effective transmis...
