1. An immobilized chalcogen body or system, comprising:
a chemical element from the chalcogen group;
an electrically conductive material; and
a hydrophilic membrane gate, the hydrophilic membrane gate comprising a plurality of carbohydrates bound to each other by intermolecular hydrogen bonding interactions, the carbohydrates comprising intermolecular hydrogen bonding —OR groups, wherein
between 1% and 69% of the —OR groups of the plurality of carbohydrates are hydrogen bond donating —OH groups, and
between 31 and 99% of the —OR groups of the plurality of carbohydrates are hydrogen bond accepting groups,
wherein the chemical element from the chalcogen group is in an elemental form, in a compound form, or in an ionic form.
