Presents some Biologically Structured Materials

Biologically inspired ‘smart’ materials

Inspiration from nature and its translation to designing the next generation of biomedical devices have received immense attention recently. Biologically inspired materials utilise billions of years of evolution to generate diverse properties that would otherwise be difficult to achieve. These materials have the potential to address many limitations associated with more traditional materials. T...

Condensation silicones: do new materials really presents better dimensional stability?

The aim of this study was evaluate the dimensional stability of some condensation silicones. The following materials were studied: Coltex/Coltoflax - Coltène, Speedex - Coltène, and Optosil Comfort/Xantopren VL Plus - Kulzer. They were evaluated by dimensional analysis and gas chromatography (GC) performed at the following times: T0, T1, T2, T3, T4, and T5 (immediately after setting, thirty min...

Nature or petrochemistry?-biologically degradable materials.

Naturally occurring polymers have been utilized for a long time as materials, however, their application as plastics has been restricted because of their limited thermoplastic processability. Recently, the microbial synthesis of polyesters directly from carbohydrate sources has attracted considerable attention. The industrial-scale production of poly(lactic acid) from lactic acid generated by f...

Intra-axonal injection of biologically active materials.

BRADY, ROSCOE O., CONSTANTINE S. SPYROPOULOS AND ICHITI TASAKI. htra-axonal injection of biologically active materiak n improved method for injection of chemicals into the squid giant axon is described. A large number of metabolically active materials were found to be without any effect upon the action potential. Tetraethylammonium chloride produced a striking prolongation of the action potenti...
