“…The addition of different chemical functionalities to the neutral block can also avoid time-consuming post-synthetic surface modifications. C3Ms have been utilized to produce various types of metallic and semiconductor nanoparticles, including metals [ 174 , 180 , 181 , 182 , 183 , 184 ], metal oxides [ 185 , 186 , 187 , 188 , 189 ], and quantum dots [ 190 , 191 , 192 ]. The coacervate core can also be used for biomimetic mineralization of silica [ 193 ], barium carbonate [ 194 ], and calcium carbonate [ 195 ].…”

The co-assembly of ionic-neutral block copolymers with oppositely charged species produces nanometric colloidal complexes, known, among other names, as complex coacervates core micelles (C3Ms). C3Ms are of widespread interest in nanomedicine for controlled delivery and release, whilst research activity into other application areas, such as gelation, catalysis, nanoparticle synthesis, and sensing, is increasing. In this review, we discuss recent studies on the functional roles that C3Ms can fulfil in these and other fields, focusing on emerging structure–function relations and remaining knowledge gaps.

“…As shown in Fig. These results demonstrate that the bioinspired Au microspheres exhibit a high catalytic activity, remarkably superior to most literature reported Au as well as Ag and Pd-based catalysts at room temperature ( Table 2) [42][43][44][45][46][47][48][49][50] The obtained values were only comparable to certain reported Au nanomaterials (Au@MIL-100 (Fe) and 2%Au@2%Ag/MOF) while exclusively inferior to those reported for Pd/C systems ( Table 2). These signals were insignificant with respect to the fluorescence signal yielded by the 1 : 5120-diluted standard positive serum of APP, indicating a highly specificity for APP.…”

A novel class of bionanocomposites based on monodisperse microparticles containing metal nanoparticles including Au, Pd, Ag and Pt were synthesized and characterized using a simple and efficient approach. The versatile nanocomposites exhibited unique possibilities as new biosensor for highly selective and sensitive immunoassays as well as a remarkable enhancement in catalytic activity in the reduction of 4-nitrophenol selected as model reaction which illustrated their potential in various different applications.Scheme 1 Spore-based hybrid microspheres loaded with highly dispersed noble metal nanoparticles and their applications in heterogeneous catalysis and immunoassay.
