The method of claim 1, wherein the at least one composition is propelled to a desired location of the at least one biological tissue. 4. The method of claim 1, further including extracting or collecting material from the at least one abraded surface of at least one biological tissue. 5. The method of claim 1, wherein the at least one biological tissue is located in at least one of in situ, in vitro, in vivo, in utero, in planta, or ex vivo. 6. The method of claim 1, wherein the at least one biological tissue is located in at least one tissue or organ related to transplantation. 7. The method of claim 6, wherein the at least one tissue or organ related to transplantation includes at least one donor or recipient tissue or organ. 8. The method of claim 7, wherein the at least one donor includes at least one cadaver. 9. The method of claim 5, wherein the at least one biological tissue is ingested by at least one subject. 10.
