摘　　要：Toxicity of nanoparticles remains to be a major issue in their application to the biomedical field. Aloe vera（AV） is one of the most widely exploited medicinal plants that have a multitude of amazing properties in the field of medicine.Methanol extract of Aloe vera can be used as a novel stabilising agent for quantum dots to reduce toxicity. We report the synthesis, structural characterization, antibacterial activity and cytotoxicity studies of ZnS：Mn quantum dots synthesized by the colloidal precipitation method, using methanol extract of Aloe vera（AVME） as the capping agent. The ZnS：Mn quantum dots capped with AVME exhibit superior performances in biocompatibility and antibacterial activity compared with ZnS：Mn quantum dots without encapsulation.Toxicity of nanoparticles remains to be a major issue in their application to the biomedical field.
