“…Noble metal aerogels (NMAs), derived from the preformed colloidal metal nanoparticles (NPs) and composed of the interfused nanowires/chains, are a new class of the aerogel family. , They not only combine the individual characteristics of monolithic aerogel materials (e.g., high specific surface areas and open interconnected porosity) and noble metal NPs (e.g., catalytic and plasmonic activity) but also possess collective and improved properties, thus attracting great attention in recent years. , To date, remarkable contributions have been devoted to the synthesis of various mono-/multimetallic aerogels and their application in electrocatalysis. − Prominent electrocatalytic activities of the NMAs with respect to the metal NPs and commercial catalysts have been well-reported in various reactions. − More interestingly, the highly branched, interfused nanowire structure of the NMAs endows them with inherent self-healing and flexible properties, which would be potentially applied as flexible sensing electrodes in wearable sensing applications. , For instance, a high-performance wearable biosensing platform has been first demonstrated by the highly porous Au hydrogels with the excellent electrocatalytic activity and flexibility for in situ monitoring of sweat glucose . Recently, considering the high cost and low abundance of the noble metals, it will be a great idea to introduce other components (e.g., carbon nanomaterials) into the NMAs to efficiently lower the cost, enrich the structural design, and enhance the activity. − However, despite the concentrated achievements, the rational design of such integrated aerogels for wearable sensing applications has been rarely explored.…”
