Since their earliest synthesis, much interest has arisen in the use of dendritic and structurally allied forms of polymer for light energy harvesting, especially as organic adjuncts for solar energy devices. With the facility to accommodate a proliferation of antenna chromophores, such materials can capture and channel light energy with a high degree of efficiency, each polymer unit potentially...

Sutures are traumatic to soft connective tissues, such as liver or lungs. Polymer tissue adhesives require complex in vivo control of polymerization or cross-linking reactions and currently suffer from being toxic, weak, or inefficient within the wet conditions of the body. Herein, we demonstrate using Stöber silica or iron oxide nanoparticles that nanobridging, that is, adhesion by aqueous nan...

Radiation sensitive polymer gels are among the most promising three-dimensional dose verification tools developed to date. Polymer gel dosimeter known by the acronym MAGIC has been tested for evaluation of its use in boron neutron capture (BNCT) dosimetry. We irradiated a large (diameter 10 cm, length 20 cm) cylindrical gel phantom in the epithermal neutron beam of the Finnish BNCT facility at ...

zinc oxide nanoparticles have been synthesized by chemical reaction method.  polyvinyl alcohol (pva) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by pva solution and nanozinc oxide. polymer blend with zno nanoparticle composite film has prepared by casting technique.  the property of nano composites depends greatly on the chemistry of polymer matrices....

The present work focused on the preparation and morphological characterization of chitosan-based nanofiber membranes, aiming at applications in medical and pharmacological areas. Membranes with nanofiber diameters ranging from 50 – 300 nm were prepared from polymer solutions through the electrospinning process. To stabilize the process, it was necessary to use poly(ethylene oxide) (PEO), which ...

Materials and Methods Formalin-fixed paraffin-embedded lung SqCC (n=137) and LADC (n=60) tissue microarrays were acquired. DSG3/p40 + Napsin A double stain cocktail (Biocare Medical, Concord, CA), TTF-1 [SPT24] and TTF-1 [8G7G3/1] antibody titers were optimized for IHC. SPT24 was optimally titered at 1:1200. The double stain antibody cocktail was detected by using a polymer double stain detecti...

Silk is a natural polymer synthesized and secreted by specialized silk gland of the silk worm. Silk is evolved as an ideal biomaterial can provide functional insight into relationships between polymer science and molecular biology. Silk proteins can be recovered from the silk during the processing chain of textile manufacture. The important characteristic of silk, especially the biocompatibilit...

Water has a key role in the functioning of all biological systems, it mediates many biochemical reactions, as well as other biological activities such as material biocompatibility. Water is often considered as an inert solvent, however at the molecular level, it shows different behavior when sorbed onto surfaces like polymeric implants. Three states of water have been recognized: non-freezable ...
