A low-cost green and reproducible microbe (Lactobacillus sp.)-mediated biosynthesis of Sb(2)O(3) nanoparticles is reported. The synthesis was performed at around room temperature. X-ray and transmission electron microscopy analyses were performed to ascertain the formation of Sb(2)O(3) nanoparticles. X-ray analysis indicated
