WebHerein, we have designed phenylboronic acid-based quaternary amine-type cationic lipids that can self-assemble into spherical lipid nanoparticles in an aqueous solution. Upon mixing insulin and the lipid nanoparticles, a heterostructured insulin complex is formed immediately arising from the electrostatic attraction. WebNov 18, 2024 · As a glucose-binding component, phenylboronic acid can be used to prepare a non-protein, synthetic polymer or gel, which can overcome the limitation of proteins [6, …
WebIn this study, we synthesized a new monomer, namely, 3,4-ethylenedioxythiophene bearing a fluoro-containing phenylboronic acid (EDOT–FPBA) for enzyme-free glucose sensing at physiological conditions. The EDOT–FPBA monomer is electropolymerized on a glassy carbon electrode (poly (EDOT–FPBA)/GCE) at a constant voltage. WebAug 23, 2024 · However, phenylboronic acid itself is limited in its utility because it only shows significant binding a few pH units above physiological pH 53,54,55. This is a structural feature that is often ...
WebNational Center for Biotechnology Information WebIt not only stabilizes the blood sugar level at any time and improves the utilization rate of insulin, but also extends the time of drug administration and reduces the pain of patients with diabetes. 8 Currently, there are three common glucose-sensitive drug systems, phenylboronic acid (PBA) and its derivatives, concanavalin A (Con A), and …
