Mixtures of colloids and supramolecular polymers exhibit stimuli-responsive phase behavior. In previous work (Peters Tuinier, Physica A 510, 233 [2018]) the were treated as fully flexible chains, while in experimental systems may have a certain degree stiffness. Here we predict that for stiff rod-like separation can occur at much lower polymer concentrations than polymers. Additionally, it is d...

A novel renewable tyrosinase-based biosensor was developed for the detection of phenol by immobilizing tyrosinase on a colloidal gold modified carbon paste electrode. Anionic colloidal gold was beneficial to the immobilization of tyrosinase and to the retention of its bioactivity to a large extent. The biosensor showed a sensitive electrochemical response to the reduction of the oxidation produ...

The non-organically supported silver nanoparticles produced via the reduction of silver oxide by hydrogen and acetvlacetone (acac) have unusual stability in aqueous solution. We have previously reported that the negative potential, the hydrophilic surface that is created by the adsorbed hydroxide ions, which resembles an oxide interface, and the low ionic strength of the solution due to the sma...
