Since the beginning of 21th century, nanoscience and nanotechnology become the most promising topics in various fields, attributing to the superior characters of nanoscaled structures. The conventional quantum dots are substituted with new family of luminescent nanostructures, owing to their interchanged optical properties, low-cost of fabrication, biocompatibility, non-toxicity, ecofriendly, hydrophilicity and superior chemical stability. Carbon quantum dots (CQDs) were recently investigated for their simple synthesis, bio-consonance, and different revelation applicability. Obeying the green chemistry aspects, this review demonstrates an overview about CQDs generated from polysaccharides in brief, with a background on CQDs discovery, chemical composition, green synthesis via exploitation of different polysaccharides (cellulose, starch, pectin, chitin, etc) as biocompatible/biodegradable abundant biopolymers. Additionally, applications of CQDs originated from polysaccharides in environmental purposes, textiles industry and medical activities were also presented.
自21世纪初以来，由于纳米级结构的卓越特性，纳米科学和纳米技术成为各个领域中最具前景的主题。传统量子点被新型发光纳米结构家族所取代，这得益于它们可互换的光学性质、低成本制造、生物相容性、无毒、环保、亲水性和卓越的化学稳定性。碳量子点（CQDs）最近因其合成简单、生物协调性和不同的潜在应用适用性而受到研究。遵循绿色化学理念，本综述简要概述了由多糖生成的碳量子点，并介绍了碳量子点的发现背景、化学成分、通过利用不同多糖（纤维素、淀粉、果胶、几丁质等）作为生物相容性/可生物降解的丰富生物聚合物进行的绿色合成。此外，还介绍了源自多糖的碳量子点在环境领域、纺织工业和医疗活动中的应用。
