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. The method of claim 5, wherein the at least one biological tissue includes at least one cell mass. 11. The method of claim 10, wherein the at least one cell mass includes at least one of a scar, pore, pit, eschar, granuloma, keloid, artheromatous plaque, abscess, pustule, infected tissue, scaling, hair follicle, necrotic tissue, stratum corneum, wrinkle, wound, tumor, skin structure, nevus, cyst, lesion, callus, neoplastic tissue, gangrenous tissue, or cellular deposit. 12. The method of claim 10, wherein the at least one cell mass includes at least one benign or malignant tumor. 13. The method of claim 12, wherein the at least one benign or malignant tumor relates to one or more of a melanoma, lymphoma, leukemia, sarcoma, blastoma, or carcinoma. 14. The method of claim 10, wherein the at least one cell mass is related to at least one blood clot, microorganism accumulation, blood vessel obstruction, duct obstruction, bowel obstruction, infection, gangrene, connective tissue destruction, tissue or organ damage, injury, white blood cell accumulation, or cancer. 15. The method of claim 1, further including delivering under a predetermined pressure to the at least one biological tissue at least one of a polymer, biopolymer, nanoparticle, or detection material. 16. The method of claim 15, wherein the detection material includes at least one electronic identification device. 17. The method of claim 16, wherein the at least one electronic identification device includes at least one radio frequency identification device. 18. The method of claim 15, wherein the detection material includes at least one radioactive element. 19. The method of claim 15, wherein the detection material includes at least one colorimetric substance. 20. The method of claim 19, wherein the at least one colorimetric substance includes one or more of a dye, pigment, or light-emitting substance. 21. The method of claim 20, wherein the light-emitting substance includes at least one of a fluorescent substance, phosphorescent substance, or quantum dot. 22. The method of claim 15, wherein the detection material includes at least one of a diamagnetic particle, ferromagnetic particle, paramagnetic particle, super paramagnetic contrast agent, or other magnetic particle. 23.
