Abstract
A microwave-plasma disinfector (Origreen) with a microwave source with multi-feed points and variable output power. It also has a low-temperature atmospheric-pressure plasma source. This versatile microwave-plasma disinfector has the ability to decontaminate heat-sensitive materials by subjecting them to a microwave-assisted plasma with controlled microwave power. This dual-action, at suitable non-destructive microwave and plasma doses, sterilizes the equipment at a lower temperature with higher effectiveness than either plasma or microwaves alone.
