Abstract

This paper reviews the use of domestic microwave ovens and fixed geometry waveguide applicators for processing of organic compounds and biomaterials. The review traces the microwave (f o ~ 2.45 GHz) technological development of proof-of-principle and batch processes highlighting their advantages and disadvantages. Amongst the rapid homogeneous and heterogeneous processes reported are the treatment of organic compounds, thawing fresh frozen blood plasma, microwave-assisted desolvation, microwave-assisted extraction of bioactive materials, cleaning of dentures, plasma cleaning of polymer surfaces and plasma deposition of carbon-nanostructures. The arc-like plasmoid generated when foodstuff such as grapes were treated in a microwave oven is explored along with a study of microwave irradiated cherry tomatoes.
