Introduction to Polyelectrolyte Microcapsules

What is/are Polyelectrolyte Microcapsules?

Polyelectrolyte Microcapsules - Polyelectrolyte microcapsules are among the most promising carriers of various sensing substances for their application inside the bloodstream of vertebrates. ^[1] In this work, the mutual arrangement of polyelectrolytes of multilayer polyelectrolyte microcapsules (with layers—[PAH/PSS]3PAH) by determination of the dissociation level of polyallylamine (PAH) from the surface of a polyelectrolyte microcapsules (PMC) of various types was studied: PMC with a dissolved CaCO3 core after preparation, PMC with an undissolved CaCO3 core and PMC with an encapsulated protein. ^[2] We offer the use of polyelectrolyte microcapsules as a protective means of bacteriophage. ^[3] The steps of the fabrication of polyelectrolyte microcapsules with the studied enzyme have been tested. ^[4] In this study, PSS doped CaCO3 microparticles were used as sacrificial templates for the fabrication of hollow polyelectrolyte microcapsules. ^[5] A method for determining the localization of charges on a solid surface using polyelectrolyte microcapsules has been developed. ^[6] In this work, we report a strategy of creating stable and size-controllable w/w droplets that can quickly form polyelectrolyte microcapsules (PEMCs) in a microfluidic device. ^[7] Here, we look at possibilities to raise the localized temperature by a laser around noble-metal nanoparticles incorporated into shells of layer-by-layer polyelectrolyte microcapsules-freely suspended delivery vehicles in an aqueous solution, developed in the Department of Interfaces, Max Planck Institute of Colloids and Interfaces, headed by Helmuth Möhwald. ^[8] The new method of bacterial spore encapsulation in polyelectrolyte microcapsules allows for degrading the nanoscale membrane shell of microcapsules. ^[9] The Janus capsule motors were fabricated by layer-by-layer assembly of UCNP-functionalized polyelectrolyte microcapsules, followed by sputtering of a platinum layer onto one half of the capsule. ^[10] This paper reports on the results of development of an improved approach to the optical encoding of polyelectrolyte microcapsules with stable, covered with the multifunctional polyethyleneglycol derivatives water-soluble QDs, as well as characterization of the optical properties, morphological and structural properties of the encoded microcapsules. ^[11] Incorporation of QDs into carriers in the form of polyelectrolyte microcapsules through layer-by-layer adsorption of oppositely charged polyelectrolyte polymers yields microcapsules with a bright fluorescence signal and adaptable size, structure, and surface characteristics without using organic solvents. ^[12] Here, we describe an approach to the optical encoding of polyelectrolyte microcapsules with the prepared stable water-soluble QDs and key stages of surface functionalization of these microcapsules with cetuximab, humanised monoclonal anticancer antibody. ^[13] The characteristics of an electrochemical biosensor based on a Prussian-blue screen-printed electrode containing glucose oxidase incorporated into polyelectrolyte microcapsules (PMC) are considered. ^[14] The structures were represented by polyelectrolyte microcapsules (PMCs) containing glucose oxidase (GOx). ^[15] We demonstrate, that encapsulation of QDs into the polymer shell using the layer-by-layer deposition method yields highly fluorescent polyelectrolyte microcapsules with a homogeneous size distribution and biocompatibility upon in vitro treatment of cancer cells. ^[16]
