Gold nanoparticles-based nanoconjugates for enhanced enzyme cascade and glucose sensing.
نویسندگان
چکیده
We have coupled gold nanoparticles with horseradish peroxidase (HRP) to assemble catalytic nanoconjugates (HRP-AuNPs) for glucose detection. We found that a proper mixing ratio of HRP/AuNPs can significantly improve catalytic activity for the cascade reaction, an effect arising from increased spatial coupling between enzymes. Such gold nanoparticle-based nanoconjugates are shown to be promising nanosensors for glucose.

A controlled release delivery system helps to overcome the problem of short life of the leutinizing hormone releasing hormone (LHRH) in blood and avoids use of multiple injections to enhance reproductive efficacy. Chitosan- and chitosan-gold nanoconjugates of salmon LHRH of desired size, dispersity and zeta potential were synthesized and evaluated at half the dose rate against full dose of bare...

Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...

Determining the catalytic activity of artificial enzymes is an ongoing challenge. In this work, we design a porphyrin-based enzymatic network through the target-triggered cascade assembly of catalytic nanoparticles. The nanoparticles are synthesized via the covalent binding of hemin to amino-coated gold nanoparticles and then the axial coordination of the Fe center with a dual-functional imidaz...
