| 1. A method of preparing a biosensor for an analyte, the biosensor comprising: a biological receptor for detecting the analyte;
an interface; and an electrical signal transducer; the method comprising:
(a) depositing the biological receptor on the interface, wherein the interface binds the biological receptor;
(b) covering the biological receptor with a film of Acacia gum solution; and
(c) curing the Acacia gum to form a solid disposed upon the interface, wherein the solid is dissolved by irrigating with an aqueous solution and
the biological receptor remains bound to the interface.
