Functional polymer hydrogels for water purification applications

Liu Y., State University of New York at Stony Brook, US

Filtration is necessary in many engineering field. Polymeric membranes have been used in filtration application for more than a decade. However, some of the contaminants, e.g. radiounuclides and toxic metals, present in soluble form in [...]

The effect of Simvastatin Acid Loaded Photocurable Hyaluronic Acid Hydrogel for Bone Regeneration In vitro and In vivo

Bae M.S., Kim S.E., Na J.S., Kwon I.K., School of Dentistry, Kyung Hee University, KR

In the field of bone tissue engineering, various biomaterials have been developed in conjugation with bone inducing factors for bone tissue regeneration due to their distinct activities of osteoconductivity and osteoinductivity. In this study, we [...]

Polymer Network on Optical Fiber Core

Kazakov S.V., Pace University, US

The ultimate goal of the research is to fabricate a cylindrical polymer network (hydrogel) on the side-surface (not the distal end) of an optical fiber core and characterize spectroscopically its swelling/de-swelling ability in response to [...]

Novel organic-inorganic nanohybrids based on poly(N,N-dimethyl acrylamide)-l-polyisobutylene amphiphilic polymer conetworks

Mezey P., Domján A., Iván B., Thomann R., Mülhaupt R., Hungarian Academy of Sciences, HU

Poly(N,N-dimethyl acrylamide)-l-polyisobutylene (PDMAAm-l-PIB) amphiphilic conetworks were synthesized. Thermal analysis (DSC), small angle X-ray scattering (SAXS) measurements and atomic force microscopy (AFM) investigations were made. Furthermore, we have successfully synthesized silver nanoparticles in the PDMAAm-l-PIB amphiphilic [...]

Synthesis of Biocompatible Nanocomposite hydrogels as a Local Drug Delivery System

Bako J., Szepesi M., Borbely J., Borbely Z.M., Hegedus C., Borbely J., Borbely Z.M., University of Debrecen, HU

Hydrogels are three dimensional hydrophilic crosslinked polymer networks, which capable of swelling in water. They have soft and elastic nature, which suggests similarities to natural tissues. Hydrogels are important in dentistry. For example, PerioChip is [...]

Morphology Studies And Potential Applications Of Poly(N,N-Dimethylacrylamide)-l-Polyisobutylene Amphiphilic Polymer Conetworks

Mezey P., Domján A., Iván B., Thomann R., Mülhaupt R., Chemical Research Center of the Hungarian Academy of Sciences, HU

Poly(N,N-dimethylacrylamide)-l-polyisobutylene (PDMAAm-l-PIB) amphiphilic conetworks were synthesized from two incompatible polymers, i.e. hydrophilic PDMAAm and strongly hydrophobic PIB in a wide range of composition (38-80 m/m % PIB). DSC and SAXS measurement results show that a [...]

Enzymatically Degradable Hydrogel Nanocomposite for Bone Regeneration

Jabbari E., He X., Sarvestani A.S., University of South Carolina, US

One approach to bone replacement involves the use of in-situ crosslinkable scaffolds for cell transplantation to promote tissue growth, nutrient diffusion, matrix production, and vascularization. Bone matrix is a composite material consisting of aqueous and [...]

Smart Bandage – A Hydrogel Supported Optical Microcavity Sensor

DeLouise L.A., University of Rochester, US

Developing new medical diagnostic technologies that can be used in the home for early detection and disease prevention is a central focus at the University of Rochester Center for Future Health. This paper is concerned [...]
