研究目的
To develop a large-scale synthesis of water-soluble AgInSe2/ZnSe quantum dots (QDs) in the absence of an inert atmosphere and assess their cell viability against different cell lines.
研究成果
The study successfully synthesized water-soluble AgInSe2/ZnSe QDs on a large scale without the need for an inert atmosphere. The QDs exhibited good optical and structural properties and were found to be biocompatible with both cancerous and normal cell lines, making them suitable for biological imaging applications.
研究不足
The synthesis of AgInSe2 QDs faces challenges such as imbalanced cation reactivity, unwanted impurities, broad size distribution, and large particle sizes. The use of inert atmosphere for large-scale synthesis has financial implications.
1：Experimental Design and Method Selection:
The synthesis involved the use of environmentally friendly precursors in aqueous media, utilizing a pressure cooker for large-scale production.
2：Sample Selection and Data Sources:
Silver nitrate, indium nitrate, sodium selenite, thioglycolic acid, gelatin, sodium borohydride, and zinc acetate dihydrate were used as precursors.
3：List of Experimental Equipment and Materials:
A 4 L conventional pressure cooker, UV–Vis spectrophotometer, photoluminescence spectrophotometer, FTIR instrument, DLS instrument, XRD diffractometer, and HRTEM were used.
4：Experimental Procedures and Operational Workflow:
The synthesis was carried out by dissolving precursors in deionized water, heating under stirring, and purifying the QDs by centrifugation.
5：Data Analysis Methods:
Optical and structural characteristics were analyzed using UV–Vis absorption, PL, FTIR, DLS, XRD, and HRTEM techniques.
