Atmospheric pressure plasma jet (APPJ) is a non-thermal plasma device used in various bio-medical and agricultural applications. Plasma is produced in these devices based on the principle of DBD in which dielectric material such as quartz and alumina cover one or both electrodes and by introducing high voltage between live and ground electrodes, discharge is ignited. The plasma so formed is touchable by bare hands. Helium and argon are mainly is used as plasma producing gases in APPJ.

1. Plasma is touchable by bare hands.
2. It can be used by 24 V batteries.
3. Can be directly used for skin infections.
4. Very handy to use.

1. Blood coagulation.
2. Removal of cancerous cells.
3. Treatment of fungal skin infections.
4. Removal of pesticides from vegetables.

Atmospheric pressure plasma jet found its various applications in the field on bio-medical and agriculture. Brief overview of its applications is as follows:

1. It can be used for coagulation of blood at faster rate and is helpful in controlling internal bleedings (APPJ is tested by us on stationary blood kept on the glass slide and compared its coagulation rate with natural clotting process).
2. It can be used for the removal of cancerous cells as it does not affect the healthy cells (tests related to lung cancer and oral cancer cells are going on).
3. It can be used for the cure of some fungal infections on the skin (preliminary test are performed on Tinea Cruris and improvement is seen on the infection).
4. It can be used for sterilization and bleaching of teeth as a substitute for hydrogen peroxide (This test is as per the literature).
5. It can be used to remove black spots from the skin (This test is also as per the literature).
6. It can be used for retaining hair dyes for the longer times (This test is also as per the literature).
7. It can be used for the removal of pesticides from vegetables (pesticides removal is performed on cabbage, capsicum, mirchi and species such as cumin seeds, red chili powder and significant decrease in its concentration is observed).
8. It can be used for increasing the germination rate of the seeds. (This test is also as per the literature)
