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 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 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 under High Gravity Field
Langmuir, 2012In the present article, we have developed a facile and rapid method to fabricate a polyelectrolyte multilayer under high gravity field and investigated the difference of mass transfer in the diffusing process between LbL self-assembled technique under high gravity field (HG-LbL) and dipping assembly.

Layer-By-Layer Self-Assembled Emerging Systems for Nanosized Drug Delivery
Nanomedicine, 2022New frontiers in the development of stimuli-responsive surfaces that offer switchable properties according to the end-use application have added a new dimension to the design of drug-delivery systems (DDS). In this respect, layer-by-layer (LbL) self-assembled technologies have attracted interest in nano-DDS (NDDS) design due to the advantage of ...

Dual Drug Delivery Microcapsules via Layer-by-Layer Self-Assembly
Langmuir, 2009The integration of hydrophobic and hydrophilic drugs in the polymer microcapsule offers the possibility of developing a new drug delivery system that combines the best features of these two distinct classes of material. Recently, we have reported the encapsulation of an uncharged water-insoluble drug in the polymer membrane.

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 Quantum Dot Constructs Using Self-Assembly Methods
Langmuir, 2010We describe the creation of CdSe/ZnS quantum dot assemblies using layer-by-layer construction strategies, using self-assembly. In the first approach, a dithiol linker was used to make multilayers of CdSe/ZnS quantum dots, while in the second biotin- and streptavidin-conjugated CdSe/ZnS quantum dots were used to make multilayer constructs.

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 ...
