Methods and materials for forming a three-dimensional (3D) structure in a material are described. An example method includes directing a liquid casting material into a mold cavity of a mold structure, where the mold cavity corresponds to a three-dimensional (3D) structure. The method further includes causing the liquid casting material to solidify within the mold cavity to form a solid structure of the casting material, removing at least a portion of the mold structure from the solid structure of the casting material, and forming a structural material around the solid structure of the casting material. The solid casting material is liquified within the structural material. The liquified casting material is evacuated from the structural material to form the 3D structure in the structural material.

Fabrication materials and processes useful to form structures in soft materials

A method for fabricating an electrode includes forming a 3D shell having a hollow interior and defining one or more openings, and directing an electrically conductive liquid through at least one of the one or more openings of the 3D shell, such that the 3D shell is at least partially filed with the electrically conductive liquid. The electrically conductive liquid can be caused to solidify within the 3D shell to form a solid electrode, or can remain a liquid to form a liquid electrode. The 3D shell can be formed having the one or more openings using a 3D printing process such as a two-photon writing system. The surface tension of the electrically conductive liquid aids in retaining the electrically conductive liquid within the 3D shell. The electrode can contact a tissue sample through one of the openings in the 3D shell.
