The ever-exploding global population coupled with its anthropogenic impact has imparted unparalleled detrimental effects on the environment and mitigating them has emerged as the prime challenge and focus of the current century. The niche of nanotechnology empowered by composites of biopolymers in the handling of xenobiotics and environmental clean-up has an unlimited scope. The appositeness of biopolymer-nanoparticles (Bp-NPs) for environmental contaminant mitigation has received unique consideration due to its exclusive combination of physicochemical characteristics and other attributes. The current review furnishes exhaustive scrutiny of the current accomplishments in the development of Bp-NPs and biopolymer nanomaterials (Bp-NMs) from various polymeric biomolecules. Special attention was provided for polymeric biomolecules such as cellulose, lignin, starch, chitin, and chitosan, whereas limited consideration on gelatin, alginate, and gum for the development of Bp-NPs and Bp-NMs; together with coverage of literature. Promising applications of tailored biopolymer hybrids such as Bp-NPs and Bp-NMs on environmentally hazardous xenobiotics handling and pollution management are discussed as to their notable environmental applications.
不断爆炸式增长的全球人口及其人为影响对环境造成了前所未有的负面影响，而减轻这些影响已成为本世纪的主要挑战和焦点。生物聚合物复合材料在处理外来污染物和环境清理方面的纳米技术具有广阔的应用前景。由于其独特的物理化学特性和其他属性的结合，生物聚合物-纳米粒子（Bp-NPs）在减轻环境污染物方面的适宜性受到了特别关注。本综述详细审查了目前在开发 Bp-NPs 和生物聚合物纳米材料（Bp-NMs）方面取得的进展，这些材料来自各种聚合物生物分子。特别关注了纤维素、木质素、淀粉、壳聚糖和几丁质等聚合物生物分子，而对明胶、藻酸盐和树胶在开发 Bp-NPs 和 Bp-NMs 方面的应用则考虑较少；同时还涵盖了相关文献。讨论了定制生物聚合物杂化物（如 Bp-NPs 和 Bp-NMs）在处理环境危害性外来污染物和污染管理方面的有前途的应用，以及它们在环境方面的显著应用。
