<p></p><p>Belousov-Zhabotinsky (B-Z) reaction driven polymerization-induced self-assembly (PISA), or B-Z PISA, is a novel method for the autonomous one-pot synthesis of polymer vesicles from a macroCTA (macro chain transfer agent) and monomer solution (“soup”) containing the above and the BZ reaction components. In it, the polymerization is driven (and controlled) by periodically generated radicals generated in the oscillations of the B-Z reaction. These are inhibitor/activator radicals for the polymerization. Until now B-Z PISA has only been carried out in batch reactors. In this manuscript we present the results of running the system using a continuously stirred tank reactor (CSTR) configuration which offers some interesting advantages.Indeed, by controlling the CSTR parameters we achieve reproducible and simultaneous control of the PISA process and of the properties of the oscillatory cargo encapsulated in the resulting vesicles. Furthermore, the use of flow chemistry enables a more precise morphology control and chemical cargo tuning. Finally, in the context of biomimetic applications a CSTR operation mimics more closely the open non-equilibrium conditions of living systems and their surrounding environments.</p><p></p>

Hyperbranched Structure

Self-assembly techniques have been demonstrated to be a useful approach to developing new functional nanomaterials. In this study, a novel method to fabricate a manganese phosphate self-assembly monolayer (SAM) on a hyperbranched polyester (HBPE-OH) nanoparticle surface is described. First, the second-generation aliphatic HBPE-OH was carboxy-terminated, phosphorylated, and then ionized with manganese by a three-step modification process. The final product of HBPE-AMPA-Mn2+ particles was obtained and characterised by FT-IR spectroscopy, 1H NMR spectroscopy, transmission electron microscopy (TEM), Zeta potential, and energy dispersive spectroscopy (EDS). Moreover, the HBPE-AMPA-Mn2+ particles were used to construct a novel biosensor for detection of superoxide anions (O2•−) released from HeLa cells. Results showed that the response currents of this biosensor were proportional to the O2•− concentration ranging from 0.79 to 16.6 μM, and provided an extremely low detection limit of 0.026 μM (S/N = 3). The results indicate that the particle-decorated electrode surface, which involved a hyperbranched structure and a surface self-assembly technology, proposed here will offer the ideal catalytic system for electrochemical enzymatic sensors.
