ABSTRACT Carbon quantum dots are nanomaterials with exceptional optical and electron transfer properties, used to address global issues like water pollution, food insecurity, energy shortages, and climate change. Their synthesis from biowastes aligns with green chemistry principles, supporting United Nations Sustainable Development Goals, and is effective in photocatalytic water treatment and renewable energy, enhancing SDGs 2, 6, and 13. They also promote plant growth and combat diseases related to SDG 2, and their biocompatibility makes them suitable biosensors for SDG 3.
