Application of metal-organic skeletons and cellulose composites in nanomedicine

Abstract

Metal-organic frameworks (MOFs) are among the most appealing porous materials with a wide range of surface chemistry, high pore structure, high specific surface area and various functionalities. They have found extensive use in a variety of industries. The handling and processing of their properties, however, continue to be quite difficult, which limits the use of MOFs. The most plentiful and environmentally friendly biopolymer in the world is cellulose, and by combining cellulose with MOFs, it is possible to create engineered materials with a variety of hitherto unachievable qualities. This is an excellent way to increase the usage of MOFs in functional materials. This review describes the synthesis of cellulose MOFs composites, mainly MOFs and cellulose compounded in aqueous solution, with two synthetic strategies: in-situ and ex-situ synthesis. By completing further post-processing procedures, the aqueous mixture of MOFs and cellulose can be further processed into four different types of composites, including powders, films, aerogels and hydrogels. We also highlight the use of MOF cellulose composites for antibacterial and drug delivery in nanomedicine. The primary present restrictions on MOF cellulose composites are also reviewed, as well as possible future research directions.
