Abstract
The present disclosure provides a substrate for an implantable microelectrode for being implanted into tissues or brought into contact with a single cell. The substrate comprises a first layer and a second layer deposited on at least a part of a first surface of the first layer. The first layer is based on a first mixture comprising a first photoinitiator and a first component with a first functional group. The second layer is based on a second mixture comprising a second photoinitiator, a second component that is an acid with a second functional group, a base to neutralize the second component, and a third component with third and fourth functional groups. The first and second components are photo-polymerizable, and the third component can cross-link the second component. A swelling capacity of the first layer is smaller than a swelling capacity of the second layer.
