Overcoming the poor physicochemical properties of pure alginate gel and the inherent shortcomings of pure metal-organic framework(MOF),alginate/MOF composite gel has captured the interest of many researchers as a tunable platform with high stability,controllable pore structure,and enhanced biological activity.Interestingly,different from the traditional organic or inorganic nanofillers physically trapped or chemically linked within neTtworks,MOFs crystals can not only be dispersed by crosslinking polymerization,but also support self-assembly in-situ under the help of chelating cations with alginate.The latter is influenced by multiple factors and may involve some complex mechanisms of action,which is also a topic discussed deeply in this article while summarizing different preparation routes.Furthermore,various physical and chemical levels of improvement strategies and available macroforms are summarized oriented towards obtaining composite gel with ideal performance.Finally,the application status of this composite system in drug delivery,wound healing and other biomedical fields is further discussed.And the current limitations and future development directions are shed light simultaneously,which may provide guidance for the vigorous development of these composite systems.
