“…They can be easily synthesized via several approaches, such as pyrolysis, hydrothermal treatment, and microwave irradiation, using natural or waste precursors, for example, cranberry beans [16], lemon juice [17], and food waste [18]. These nanomaterials provide interesting and multifunctional applications, such as chemical [19] and biological sensing [20], drug delivery [21], photocatalysis [22], and electrocatalysis [23]. In this work, jackfruit seeds were used as precursors to synthesize carbon dots due to their high organic carbon contents.…”
