Research on sensor materials has expanded with the advancement of sensing technologies across industries. Carbon dots (CDs) derived from organic waste and biomass have attracted widespread interest in applications their prominent properties (e.g., photoluminescence biocompatibility). The use non-biomass (NBW) as a raw material thus becomes important to make production process sustainable without additional treatments cause environmental pollution. Due scarcity research NBW-based CDs, this review explores synthesis methods, properties, CDs. potential CD sensors for metal ions Fe3+ Cu2+) humidity been evaluated various respects. In case Cu2+, CDs medical gloves polyolefin pyrolysis residue exhibit lowest limit detection values 0.29 nM 6 nM, respectively, among all examined parallel basis. humidity, graphite-based best performance, minimum response time 15 s. This overall highlights challenges opportunities application toward construction efficient systems based performance evaluations.
