DESCRIPTION:Dr. Jean-Michel Pouvesle - GREMI\, UMR 7344 CNRS/Université d
 ’Orléans\, F\nThe last decade has seen an impressive increase of the re
 search dedicated to the biomedical applications of low temperature plasmas
 \, especially with plasma sources working at atmospheric pressure. In this
  new trend\, beside decontamination/sterilization and surface treatment wh
 ich have already a quite long story through low pressure plasma research a
 nd developments\, medical applications are tacking an increasing place und
 erlined by the actual numerous clinical trials. Medical applications of lo
 w temperature plasmas now concern a very wide range of domains\, including
  primary hemostasis and blood coagulation\, dental care\, skin decontamina
 tion and hygiene\, wound and ulcer treatment\, dermatology\, cancer treatm
 ent. Biological applications are also now extended to agriculture and\, mo
 re recently\, to cosmetic. Despite the huge number of in vitro and in vivo
  experiments there are still a large number of remaining questions concern
 ing the processes leading to the observed results\, but also the specific 
 role of the different plasma components that are directly linked both to t
 he plasma production devices and the presence of the living target (biolog
 ical tissues and materials\, organs and their direct environment). Beside 
 the radical production\, we will emphasize on the potential role of the st
 rong electric field generated around the plasma plume of atmospheric plasm
 a jet systems\, and discuss possible changes induced in microenvironment o
 f tissues or tumors. We will also emphasize on the fact that plasma diagno
 stics must be performed in real treatment conditions.\n\nIn this talk\, af
 ter a presentation of the context\, the plasma devices\, and the main appl
 ications\, considering the specific case of cancer treatment\, we will go 
 through what have been already demonstrated concerning in vitro and in viv
 o experiments\, what problems are directly linked with discharges includin
 g recent results on electric field measurements in plasma biological appli
 cation conditions\, what are the challenges in front us\, and finishing tr
 ying to draw what are the main perspectives in the domain.
