Abstract:	In this work, for the first time the results of studying the microstructure of manganese dioxide nanoparticles stabilized with sulfur-containing amino acids are presented. According to the results of scanning electron microscopy, nanoparticles with a diameter of 15-30 nm were presented in the samples. The optimal mass ratios of precursors were established by means of spectrophotometry, to obtain stable sols of manganese dioxide nanoparticles. The optimal mass ratios were: KMnO4: methionine - 1:1 and KMnO4: cysteine - 3 :1 . Investigation of the effect of the medium active acidity on the stability of manganese dioxide nanoparticles showed that MnO2 samples obtained with methionine are stable at 4 <= pH <= 11, and with cysteine - at 5 <= pH <= 8
