20110089317 | Polarization Standards for Microscopy - The present invention describes the development of thin film calibration strips for microscopy/spectroscopy systems and a simple method/routine to conduct instrument calibration using partially (uniaxially) oriented strip to calibrate microscopy system without the prior knowledge of exact polarization of the strip. The invention describes results from studies including a styryl derivative (LDS 798) embedded in poly(vinyl alcohol) (PVA) film. These films were progressively stretched up to 8 folds. Vertical and horizontal components of absorptions and fluorescence were measured and dichroic ratios were determined for different film stretching ratios. The stretched films have high polarization values for isotropic excitation. The isotropic and stretched PVA films doped with LDS 798 can be used as etalons in near infra red (NIR) spectroscopic measurements. The high polarization standards of the present invention have applications in NIR imaging microscopy where they can be used for correcting for instrumental factor in polarization measurements. | 04-21-2011 |
20090110739 | Targeted cancer chemotherapy using synthetic nanoparticles - Compositions and methods for delivery of a pharmaceutical to an individual. Delivery vehicles are provided in a formulation of a pharmaceutical that is encapsulated in a synthetic self assembled nanoparticle that includes a lipid binding protein and a lipid monolayer. The interior of the particle represents a hydrophobic core region where lipophilic highly-water insoluble drug molecules may be incorporated. In contrast to liposomes, that include an aqueous interior core surrounded by phospholipid bilayer, the drug carrier nanoparticle described here is composed of a monolayer and a hydrophobic interior. | 04-30-2009 |
