1. A wirelessly stimulatable probe comprising:
- an untethered, dispersible element attachable to tissue structure and substantially less than 100 micrometers in a longest dimension, the dispersible element absorbing electromagnetic radiation to produce an electrical current local to the dispersible element;
energy of the electromagnetic radiation providing the sole source of electrical power for the dispersible element in interacting with the tissue structure.

Abstract
Untethered micro or nanoscale probes may be dispersed within tissue to be individually addressed through external electromagnetic radiation to create local electrical currents used for direct stimulation, alteration of cellular potentials, or the release or modification of contained or attached chemical compounds.

10. A cellular scale addressable probe array comprising:
-
a plurality of untethered, dispersible elements attachable to spatially separated tissue structure, the dispersible elements less than 100 micrometers in a longest dimension and absorbing electromagnetic radiation to produce an electrical current local to the dispersible element, energy of the electromagnetic radiation providing substantially the sole source of electrical power for the dispersible element in interacting with the tissue structure; and an electromagnetic radiation source steerable to produce the electrical current local to a predetermined subset of the dispersible elements. - View Dependent Claims (11)

12. A method of wirelessly stimulating tissue structure comprising:
-
locating one or more untethered, dispersible elements substantially less than 100 micrometers in a longest dimension in the tissue structure; and stimulating the elements with electromagnetic radiation to produce an electrical current local to the elements, the electrical current generated substantially solely from energy of the stimulating electromagnetic radiation absorbed by the dispersible elements. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
