Cross-scale modulation for aqueous fabrication of monodisperse Cu2−xE (E = S, Se, Te) nanocrystals and supraparticles

Versatile fabrication of metal sulfide supraparticles by an in situ decomposition–assembly strategy

“…In previous studies, cysteine was also used as a stabilizer in the preparation of nanomaterials, and metal sulfide nanomaterials were obtained by applying additional sulfur sources. 22,29…”

“…In previous studies, cysteine was also used as a stabilizer in the preparation of nanomaterials, and metal sulde nanomaterials were obtained by applying additional sulfur sources. 22,29 Herein, through our in situ decomposition-assembly strategy utilizing cysteine, four types of metal sulde SPs are successfully obtained (Fig. 3).…”

“…In our previous studies, we have found that, with the help of citrate as the capping ligand, amino acid molecules could facilitate the in situ one-step assembly of copper chalcogenide SPs in the aqueous phase, which has also been observed by other groups. 22 This allows the possible design of a green and efficient assembly route with small amino acid molecules for metal sulfide SPs that are suitable for bio-applications.…”
