The effect of the plasma needle on tumoral cell lines apoptosis.
In this paper, we present the effect of the plasma needle on tumor cell surface. The plasma is generated at the tip of a metal needle by using a radio-frequency generator of 13.56 MHz, 100's V amplitude. In our study we investigated the interaction of non-thermal plasma (plasma needle) with living monolayer tumour cells in culture medium. We applied short needle to sample distance (1 mm) at temperature of 25 degrees C, 30 degrees C and 37 degrees C, respectively. Our data sugest that the plasma needle reduces the viability and induces apoptosis of tumour cells. These activities may be very useful in dermatology, where a part of the tissue must be removed with high-precision, without damage to the adjacent cells and without inflammatory reaction.
