Local generation of hot or cold plasmas

After tuberculosis seemed to be nearly eradicated, like plague, new drug resistant forms of said disease have reappeared, mainly in conjunction with the HIV virus.

According the GERMAN AERZTZEBLATT 107, March 2010 in, some countries more than 6% of all infections are resistant to all known medicaments.

Cold plasmas can be used for destroying bacteria or tumour cells, as disclosed by EP1526875, or for activating given forms of drugs, e.g. medications stored in liposomes or those being present in a non-active pharmaceutical form.

More generally speaking, cold plasma jets and their interaction with materials and media have recently been very active research topics. The low gas temperature enables applications in various fields, including medicine. In bioapplications, for example, it involves radiation and reactive species created by the plasma jet to modify or kill prokaryotic cells (i.e. bacteria) or eukaryotic cells (i.e. mammalian cells).

A pulsed cold plasma plume/jet turns out to be a series of high-velocity plasma "bullets" or "packets." These bullets travel at hypersonic speeds and these transport with them chemically reactive species and deliver them to the surface of samples under treatment.

See for example, The Plasma Pencil : A Source of Hypersonic Cold Plasma Bullets for Biomedical Applications  ; M. LAROUSSI et al.    

The cold plasma required for local application or activation of medications can be produced with inhaled gases like nitrogen, helium, argon or xenon.

The problem is to induce such plasmas, locally, i.e. inside an organism.

To generate cold plasma, an electromagnetic wave with the wavelength ۵ is required. If an electromagnetic (radio) wave is emitted, which is in the same xyz-axis as anot...
