Simulations were carried out of the polymer-polymer chain interpenetration, diffusion, and adhesion of crosslinked polymers with dangling chain ends. Concentration profiles were determined for various polymer chain lengths and densities. The penetrat

The fracture energy required to separate layers of hydrogel films was investigated to evaluate the impact of bulk polymer diffusion on hydrogel/hydrogel adhesion and to obtain molecular information on the fracture energy in polymer mucoadhesion. Poly

The role of diffusion in gel/gel adhesion was examined by near-field FTIR microscopy. Using a near-field FTIR microscopy technique, compositional maps were obtained with improved spatial resolution and enhanced signal to noise ratio. With this techni

The primary goal of bioadhesive controlled drug delivery is to localize a delivery device within the body to enhance the drug absorption process in a site-specific manner. Bioadhesion is affected by the synergistic action of the biological environmen

Two-Photon initiated polymerization (TPIP) has shown great promise for fabrication of complex micro- and nano-structures. The method has been used to fabricate such structures over small areas (< 1 mm2) because of slow fabrication speeds and resultin

Cured epoxy resins were prepared by reacting N,N,N'N'-tetraglycidyl-4,4'-diaminodiphenylmethane(TGDDM) with the cross-linking agent 4,4'-diaminodiphenyl sulfone (DDS). The components were cured at 80°C for 2 h, 100°C for 1 h, 150°C for 4 h, and 20

The exponential expression of solute release from polymeric devices can be written in terms of the release mechanism's diffusional and relaxational contributions. The general form of this equation's exponent is related to the geometric shape of the r
