Layer-by-Layer Self-Assembly of Graphene Nanoplatelets
Langmuir, 2009In this report, graphene nanoplatelets were self-assembled through the layer-by-layer (LBL) method. The graphene surface was modified with poly(acrylic acid) and poly(acryl amide) by covalent bonding, which introduced negative and positive charge on the surface of graphene, respectively.

Layer-by-layer self-assembled shells for drug delivery
Advanced Drug Delivery Reviews, 2011There are several requirements for the safe and effective delivery of therapeutic agents for human use. Direct injection of drugs may cause side effects due to their permeation to other, undiseased regions of the body so that concealment and targeting with appropriate materials is a critical consideration in the design of practical drug delivery ...

Layer-by-Layer Self-Assembly Vectors for Gene Delivery
Current Gene Therapy, 2011The success of gene therapy largely relies on the development of high-efficient and low-toxic gene delivery vectors. Nanovector-based delivery of nucleic acids is a very promising approach for the effective transfer of genetic materials into cells. Compared with encapsulating of nucleic acids inside biodegradable nanoparticles which often suffers from ...

Layer-by-layer self-assembly of Prussian blue colloids
Journal of Colloid and Interface Science, 2003The adsorption of Prussian blue (PB) colloids within layers of polyelectrolytes has been achieved by a reiterative immersion-rinse approach. Multilayer assemblies consisting of alternate layers of these components have been prepared by the layer-by-layer (LbL) self-assembly technique.

Layer by Layer Self-Assembly of Immunoglobulins for Piezoelectric Biosensors
2007 2nd IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2007The immobilization of two different immunoglobulins by means of the layer by layer self assembly technique (LbL) was studied and evaluated for its use in the development of piezoelectric biosensors. Namely an antibody specific to transforming growth factor pi (anti-TGF-pl) and one specific to taxol were immobilized onto the surface of piezoelectric ...

Silica Nanowires Fabricated with Layer-by-Layer Self-Assembled Nanoparticles
Journal of Nanoscience and Nanotechnology, 2006In this paper we demonstrate an approach to fabricate silica nanowires by combining "top-down" e-beam lithography and "bottom-up" layer-by-layer (LbL) nano self-assembly techniques. The simple and low-cost LbL self-assembly technique is used to grow silica nanoparticle thin film, while the e-beam lithography based lift-off technique is implemented to ...

Layer-by-Layer Self-Assembly Immobilization of Catalases on Wool Fabrics
Applied Biochemistry and Biotechnology, 2013A 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.

Introduction to nanocoatings produced by layer-by-layer (LbL) self-assembly
Advanced Drug Delivery Reviews, 2011Studies 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.

Molecular Dynamics Simulations of Electrostatic Layer-by-Layer Self-Assembly
Physical Review Letters, 2004Electrostatic assembly of multilayered thin films through sequential adsorption of polyions in layer-by-layer fashion utilizes the strong electrostatic attraction between oppositely charged molecules. We perform molecular dynamics simulations of multilayers of flexible polyelectrolytes around a charged spherical particle. Our simulations establish that
