Enzymes, immobilized on pH/temperature/ion-responsive carriers, relieve poor contact and could be conveniently recycled as well. Enzymes were immobilized on pH-responsive carriers often by covalent method, which was better than non-covalent method (adsorption). The immobilized enzymes showed slight steric hindrance for enzymatic reaction, but always lose much activity during recycle process. The Km values were often increased significantly via immobilization on temperature/ion responsive carriers, while the immobilized enzymes expressed superior reusability. Both covalent and non-covalent methods were fit for enzymes to be immobilized on temperature-responsive carriers. Non-covalent method (entrapment) was preferential choose for enzymes to be immobilized on ion-responsive carriers. Many drawbacks, such as large activity loss and slow respondence during stimulus occurrence, seriously restrained the effect of the immobilized enzymes. It was supposed to open up special stimuli-responsive materials for enzymes immobilization, and choose proper immobilization methods, correspondingly.

AbstractClay aerogels are a relatively unexplored form of matter that are only now being investigated for use in the reinforcement of organic polymers. We have recently demonstrated an efficient process for producing these aerogels; we now report our preliminary work describing the preparation and properties of polymer/clay aerogel composites, including temperature-responsive materials.
