1. A particle, consisting of: a metal carbonate; anda metal;wherein the particle contains more than 70 percent by weight of the metal carbonate, and the particle has an average maximum dimension of less than 500 nanometers. 2. The particle of claim 1, wherein the particle consists of a metal carbonate outer shell around a metal core. 3. The particle of claim 1, wherein the metal carbonate is uniformly dispersed throughout the particle. 4. The particle of claim 1, wherein the metal is silver. 5. The particle of claim 1, wherein the metal carbonate is silver carbonate. 6. A pharmaceutical composition, comprising: a particle comprising a metal carbonate and a metal; anda pharmaceutically acceptable carrier,wherein the particle contains more than 70 percent by weight of the metal carbonate, and the particle has an average maximum dimension of less than 500 nanometers. 7. The composition of claim 6, wherein the metal carbonate is uniformly dispersed throughout the particle. 8. The composition of claim 6, wherein the composition is a cream, a nanodispersion, a solution, a foam, a gel, a lotion, a paste, an ointment, a spray, a drop, or a suppository. 9. A pharmaceutical composition, comprising: a particle consisting of a metal carbonate outer shell around a metal core; anda pharmaceutically acceptable carrier,wherein the particle contains more than 70 percent by weight of the metal carbonate, and the particle has an average maximum dimension of less than 500 nanometers. 10. The composition of claim 9, wherein the metal is silver. 11. The composition of claim 9, wherein the metal carbonate is silver carbonate. 12. The composition of claim 9, wherein the composition is a cream, a nanodispersion, a solution, a foam, a gel, a lotion, a paste, an ointment, a spray, a drop, or a suppository. 13. A pharmaceutical composition, comprising: a particle comprising a metal carbonate and a metal, the metal being silver; anda pharmaceutically acceptable carrier,wherein the particle contains more than 70 percent by weight of the metal carbonate, and the particle has an average maximum dimension of less than 500 nanometers. 14. The composition of claim 13, wherein the particle consists of a metal carbonate outer shell around a metal core. 15. The composition of claim 13, wherein the metal carbonate is uniformly dispersed throughout the particle. 16. The composition of claim 13, wherein the metal carbonate is silver carbonate. 17. The composition of claim 13, wherein the composition is a cream, a nanodispersion, a solution, a foam, a gel, a lotion, a paste, an ointment, a spray, a drop, or a suppository. 18. A pharmaceutical composition, comprising: a particle comprising a metal carbonate and a metal, the metal carbonate being silver carbonate; anda pharmaceutically acceptable carrier,wherein the particle contains more than 70 percent by weight of the metal carbonate, and the particle has an average maximum dimension of less than 500 nanometers. 19. The composition of claim 18, wherein the particle consists of a metal carbonate outer shell around a metal core. 20. The composition of claim 18, wherein the metal carbonate is uniformly dispersed throughout the particle. 21. The composition of claim 19, wherein the composition is a cream, a nanodispersion, a solution, a foam, a gel, a lotion, a paste, an ointment, a spray, a drop, or a suppository.
