Laccases stabilization with phosphatidylcholine liposomes

In recent years, there has been an upsurge of interest in enzyme treatment of textile fibres. Enzymes are globular proteins whose catalytic function is due to their three dimensional structure. For this reason, stability strategies make use of compounds that avoid dismantling or distorting protein 3D structures. This study is concerned with the use of microencapsulation techniques to optimize e...

Tunable fusion and aggregation of liposomes triggered by multifunctional surface-cross-linked micelles.

Water-soluble organic nanoparticles were prepared by cross-linking the micelles of a tripropargylated cationic surfactant by a diazide cross-linker in the presence of Cu(I) catalysts. The nanoparticles were decorated with hydrophilic ligands of different lengths on the surface. By interacting with negatively charged liposomes through tunable electrostatic interactions, these nanoparticles induc...

A Model of Irreversible Electro-Oxidation Inhibited by Either Adsorption or Surface Complexation of the Product

Theoretical models of irreversible electro-oxidation of dissolved reactant giving dissolved product on the stationary planar electrode are developed for the conditions of staircase cyclic voltammetry. In the first model it is assumed that the product is adsorbed on the electrode surface and that the adsorbate prevents the transfer of electrons. In the second model it is assumed that the electro...

Steric stabilization of liposomes by pH-responsive N-isopropylacrylamide copolymer.

The aim of this study was to characterize a pH-sensitive liposome formulation bearing a terminally alkylated N-isopropylacrylamide (NIPAM) copolymer with regard to its pH responsiveness, surface properties, and pharmacokinetics. The interacting forces between two lipid bilayers bearing the anchored NIPAM copolymer were measured with a surface force apparatus. The pH-triggered content release wa...
