Abstract

Sonochemistry has many applications in biomedical engineering owing to its
ability to break chemical bonds. It can also be used to facilitate the
preparation of aqueous quantum dots (QDs) dispersions during
microemulsion formati on. Cavitation, bubble growth, and collapse during
sonication facilitate the formation of microemulsions between a solvent and
water. Sonication was employed in this study to prepare aqueous copper
indium sulfide colloidal zinc sulfide (CuInS2/ZnS) QD dispersions using
different solvent systems. The resultant QDs were characterized by UV-vis
absorption, photoluminescence, and dynamic light scattering. Hexane was
determined to be the best solvent for the preparation of QD dispersions with
the resultant QDs (30 nm in diameter) retaining their chemical integrity and
>30% of their quantum yield. CuInS2/ZnS QD dispersions in water can be
directly prepared without any non-polar solvent and it has shown high
quantum yield. Further, it was also shown that less-toxic, which is efficient
in labeling tumor cells derived from human liver cancer (HepG2). It’s
evident that sonication was found to be an efficient alternative approach for
preparing aqueous QD dispersions without the need for surface
modification, or the use of non-polar solvents during microemulsion
formation.
