Advances in anti-adversity of biological composites based on metal-organic frameworks

Abstract

Metal-organic frameworks (MOFs) are formed by self-assembly of metal ions or clusters with organic ligands, and are widely used in the fields of catalysis, sensing, energy and biomedicine. Recently, biological composites based on MOFs have attracted increasing attention. MOFs can be used as a platform for encapsulating bioactive substances due to the advantages such as large pore capacity, large specific surface area and diverse structure composition. These features can protect bioactive substances from adverse conditions, e.g. high temperature, high pressure, and organic solvents, thus improving the anti-adversity of bioactive substances. This review summarizes the advances of using MOFs as protective coatings to improve the anti-adversity of different bioactive substances, and introduces the synthesis strategy of MOFs-based biological composites, with the aim to promote the practical application of MOFs-based biological composites.
