Electroporation is an appealing way of stimulating living cells, which causes permanent or temporary nanoporosities in the structure of the biological objects. However, the technique has a disadvantage such as a requirement of contact between the electrodes and the cell medium. In this review, a methodology of contactless treatment of the biological objects using pulsed magnetic fields is proposed. The eukaryotic micro-organisms Achlya americana and Saprolegnia diclina have been used in the study and magnetic fields up to 7 T were applied, which caused effects similar to irreversible electroporation resulting in the death of the species. The proposed technique is applicable for different types of the biological cells or micro-organisms and possibly can be used in the area of cancer, antifungal treatment and other biotechnological fields.
