This report describes a dual-healing method for self-healing hydrogels, in which stellate mesoporous silica (STMS) was used to prepare surface-functionalized microcapsules.

A novel strategy based on nanoprobes for signal amplification was introduced in an electrochemical immunoassay platform.

As promising intelligent materials, self-healing materials have the capability of healing or repairing inflicted damage. Simply, inexpensive and commercial synthetic process is one of the hard issues. By using a facile one-pot two-step methodology, polyacrylonitrile-r-poly(butyl acrylate) (PAN-r-PnBA) was successfully prepared and modified to Fe 3+ /tetrazole-based metallopolymers (MPs) with significant self-healing properties. FeCl 3 $6H 2 O was used as a catalyst to modify cyano groups with sodium azide (NaN 3 ) and generate tetrazole group for coordinating with FeCl 3 $6H 2 O itself. The results indicated that the prepared MPs without any stimulus, can rapidly and autonomously heal inflicted damageat ambient temperature.These self-healing materials which were rapidly prepared with commercial and inexpensive substrates could facilitate the potential for application in a wide range.
