Abstract
Certain embodiments disclosed herein relate to compositions, methods, devices, systems, and products regarding frozen particles. In certain embodiments, the frozen particles include materials at low temperatures. In certain embodiments, the frozen particles provide vehicles for delivery of particular agents. In certain embodiments, the frozen particles are administered to at least one biological tissue.
