Abstract: The present invention generally relates to injectable electronics. In some aspects, the present invention is generally directed to systems and methods for interfacing an electrical cable with electrical elements, such as nanoscale wires, that are injected or otherwise introduced into a subject. The subject may be living or non-living.

The electrical contacts may be in electrical communication with the electrical elements using a joining portion. The circuit board can also be connected to an electrical cable that can be attached, for example, to a computer. In some cases, the electrical cable can be attached or detached to or from the circuit board, e.g.

Abstract: The present invention generally relates to nanoscale wires, including anisotropic deposition in nanoscale wires. In one set of embodiments, material may be deposited on certain portions of a nanoscale wire, e.g., anisotropically. For example, material may be deposited on a first facet of a crystalline nanoscale wire but not on a second facet. In some cases, additional materials may be deposited thereon, and/or the portions of the nanoscale wire may be removed, e.g., to produce vacant regions within the nanoscale wire, which may contain gas or other species. Other embodiments of the invention may be directed to articles made thereby, devices containing such nanoscale wires, kits involving such nanoscale wires, or the like.
