ASSEMBLY OF MULTICOMPONENT PROTEIN FILMS BY MEANS OF ELECTROSTATIC LAYER-BY-LAYER ADSORPTION
Multilayer films which contain ordered layers of more than one protein species were assembled by means of altemate electrostatic adsorption mostly with positively charged poly(ethy1enimine) (PEI) or… Expand
In-vitro release characteristics of tetracycline HCl, khellin and nicotinamide adenine dineculeotide from halloysite; a cylindrical mineral.
The use of halloysite clay as a low cost alternative to more traditional microencapsulation systems is reported. Halloysite is an alumino-silicate clay which demonstrates a predominately cylindrical… Expand

Halloysite is a naturally occurring clay mineral with submicron sized hollow cylindrical morphology. Halloysite morphology, structure and properties were characterized by using SEM, TEM, XRD, FT-IR… Expand
Direct Electrochemistry of Myoglobin and Cytochrome P450cam in Alternate Layer-by-Layer Films with DNA and Other Polyions
Alternate layer-by-layer polyion adsorption onto gold electrodes coated with chemisorbed mercaptopropanesulfonic acid gave stable, electroactive multilayer films containing the proteins myoglobin and… Expand
Functional polymer–clay nanotube composites with sustained release of chemical agents
Abstract Natural halloysite clay nanotubes are described as inorganic reinforcing materials for polymers. Loading these tubes’ 15-nm diameter lumens with chemical agents, including bioactive… Expand

Halloysite clay tubes have 50 nm diameter and chemically different inner and outer walls (inner surface of aluminum oxide and outer surface of silica). Due to this different chemistry, the selective… Expand
Assembly, structural characterization, and thermal behavior of layer-by-layer deposited ultrathin films of poly(vinyl sulfate) and poly(allylamine)
Layer-by-Layer-Coated Gelatin Nanoparticles as a Vehicle for Delivery of Natural Polyphenols.
Natural polyphenols with previously demonstrated anticancer potential, epigallocatechin gallate (EGCG), tannic acid, curcumin, and theaflavin, were encased into gelatin-based 200 nm nanoparticles… Expand
CLAY NANOTUBES FOR ENCAPSULATION AND SUSTAINED RELEASE OF DRUGS
50-nm diameter halloysite clay nanotubules with 15 nm lumen were used for loading poorly soluble drugs and sustaining their release. Loading was optimized by varying pH and alcohol/water ratio in the… Expand
