Re-engineering a Healthy Eye Tissue to Restore Damaged Eyesight
02 Aug 2007 | | Contributor(s):: Margarita Shalaev
Age-related macular degeneration (AMD) is an eye disease that is the leading cause of blindness in the USA and Western Europe. It affects over one million people in the United States alone. One of the symptoms of AMD is a diseased Bruch’s membrane, which is an important layer in the eye. Our...
Biosensing applications of Plasmon Resonance in gold nanoparticles
02 Aug 2007 | | Contributor(s):: Karina Moore
Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...

26 Jun 2007 | | Contributor(s):: David D. Nolte
While single-molecule detection through fluorescence has now become common-place, there has been no analogous single-molecule capability using direct detection approaches such as interferometry. This limitation is slowly yielding to high-speed interferoemtric detection that is pushing the...
Charge Transfer Across an Energy Transducing Integral Membrane Protein Complex
31 May 2007 | | Contributor(s):: William A. Cramer
The cytochrome bc complexes of the mitochondrial respiratory and photosynthetic electron transport chains are hetero-oligomeric integral membrane proteins. These proteins are responsible for most of the energy transduction and transport activities across biological membranes. Such complexes...
Polymers for nanoparticle and nanocrystal formulations for drug delivery
