Sonication-assisted Layer-by-Layer self-assembly nanoparticles for resveratrol delivery

Materials Science and Engineering: C, 2019
This paper advances the development of a novel drug nanodelivery solution to the oral administration of resveratrol (RSV), a low soluble drug whose recognized therapeutic applications are circumscribed when administered in the free compound form. Layer-by-Layer (LbL) self-assembly is an emergent nanotechnology proposed to address this concern with ...

Preparation of Functional Aptamer Films Using Layer-by-Layer Self-Assembly

Biomacromolecules, 2009
Advances in many aptamer-based applications will require a better understanding of how an aptamer's molecular recognition ability is affected by its incorporation into a suitable matrix. In this study, we investigated whether a model aptamer system, the sulforhodamine B aptamer, would retain its binding ability while embedded in a multilayer ...

Layer-by-Layer Self-Assembly Immobilization of Catalases on Wool Fabrics

Applied Biochemistry and Biotechnology, 2013
A new immobilization strategy of catalases on natural fibers was reported in this paper. Catalase (CAT) from Bacillus subtilis was assembled into multiple layers together with poly(diallyldimethylammonium chloride) (PDDA) on wool fabrics via layer-by-layer (LBL) electrostatic self-assembly deposition.

Hierarchically Assembled Nanofibers Created by a Layer-by-Layer Self-Assembly

Journal of Nanoscience and Nanotechnology, 2016
We report the hierarchically assembled nanofibers created by LbL self-assembly depending on the PSS-PAA fraction in the blend solutions and pH during bulid-up of the PAH/(PSS-PAA) multilayer films. The multilayer [(PEI/blend)/(PAH/blend)4] films with ρPAA (PSS-PAA fraction in the blend solutions) = 0.0 in the blend solution exhibited surface ...

Molecular Composite Coatings on Nafion Using Layer-by-Layer Self-Assembly

ACS Applied Materials & Interfaces, 2015
Controlled growth of nanometer-scale multilayered coatings of negatively charged sulfonated poly(benzobisimidazole) (SPBI), complexed with positively charged poly(2-vinylpyridine) (P2VP) on quartz, and Nafion membrane as substrates has been explored. Both polymers, SPBI and P2VP, possess a net charge in methanol as a result of the dissolution of SPBI ...

Introduction to nanocoatings produced by layer-by-layer (LbL) self-assembly

Advanced Drug Delivery Reviews, 2011
Studies on the adsorption of oppositely charged colloidal particles ultimately resulted in multilayered polyelectrolyte self-assembly. The inception of layer-by-layer constructed particles facilitated the production of multifunctional, stimuli-responsive carrier systems.

Layer-by-layer self-assembly of polyelectrolyte functionalized MoS₂nanosheets

Nanoscale, 2016
Few-layered polyelectrolyte functionalized MoS2 nanosheets were obtained for the first time through in situ polymerization of MoS2 nanosheets with poly(acrylic acid) and poly(acrylamide), both of which demonstrated excellent dispersibility and stability in water.

Layer-by-layer self assembly of polyelectrolytes on colloidal particles

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Abstract Polyelectrolytes have been consecutively adsorbed onto charged polystyrene latex particles, forming stable ultrathin multilayer films. Film growth has been followed by electrophoresis, dynamic light scattering, single particle light scattering and fluorescence intensity measurements.
