Abstract

Cellulose is the earth’s leading natural polymer. It is known for its properties like biocompatibility, high mechanical strength, cost-effectiveness and lightweight. Nanocellulose displays better properties as compared to the native cellulose fibre. The nanocellulose is very remunerative in the arenas of routine application especially in health care, food industry, sanitary products and many more. In the biomedical area, cellulose-based products are utilized in applications like wound healing, dental applications, drug delivery, antimicrobial material, etc. Nanocellulose biomaterials have been commercialised, representing the material of new generation. With the objective to comprehend the contribution of nanocellulose in the current status and future development in biomedical utilisations, the review is focused on cellulose, nanocellulose, types and sources of nanocellulose, its preparation, characteristics, constraints related to its composites through the analysis of certain scientific reports.

摘要

纤维素是地球上领先的天然聚合物。它以其生物相容性、高机械强度、成本效益和重量轻等特性而闻名。与天然纤维素纤维相比，纳米纤维素显示出更好的特性。纳米纤维素在常规应用领域非常有利可图，尤其是在医疗保健、食品工业、卫生产品等领域。在生物医学领域，纤维素基产品被用于伤口愈合、牙科应用、药物输送、抗菌材料等应用。纳米纤维素生物材料已经商业化，代表了新一代材料。为了理解纳米纤维素在生物医学应用的现状和未来发展中的贡献，本综述重点关注纤维素、纳米纤维素、
