20100053928 | LIGHT EMITTING DEVICES MADE BY BIO-FABRICATION - A light emitting device includes a substrate layer, a first injection contact positioned over the substrate layer, a first dielectric layer positioned over the first injection contact, a light emission layer positioned over the first dielectric layer, a second dielectric layer positioned over the light emission layer and a second injection contact positioned over the second dielectric layer. The light emission layer includes an organic template having binding sites for binding nanoparticles into an array. The wavelength of emitted light is dependent upon the size of the nanoparticles and the pitch of the array. The light emitting device may include a first plurality of binding sites for binding a first set of nanoparticles and a second plurality of binding sites for binding a second set of nanoparticles. The wavelength depends upon a ratio of the first plurality to the second plurality of binding sites. | 03-04-2010 |
20100278892 | HIGH AFFINITY METAL-OXIDE BINDING PEPTIDES WITH REVERSIBLE BINDING - A dodecamer peptide, and its modified variant, having a repeating glycine-lysine sequence was created and found to bind with high affinity to oxide surfaces and certain activated polymeric surfaces. Reversible binding characteristics of the peptides were demonstrated. The peptides were integrated with proteins, cells and fusion proteins to provide attachment of the proteins, cells and fusion proteins to solid material structures. The peptides can be used to functionalize surfaces of components within mechanical, in mechanical, biomechanical, micro fluidic, electronic, bioelectronic, bio-optical, and biochemical devices. Experiments were carried out to assess functionalization and reusability of a suspended mass resonator's cantilever. | 11-04-2010 |
