20080213783 | SITE-SPECIFIC ENZYMATIC DEPOSITION OF METAL IN SITU - The present invention provides compositions, kits, assembles of articles and methodology for carrying out processes that permit biological enzymes to act directly on metals and metal particles. In particular, the invention relates to use of enzymes to selectively deposit metal to the vicinity of a target molecule. The invention also relates to linking of metals to enzyme substrates, control of enzymatic metal deposition and applications of enzymatic metal deposition to sensitively and selectively detect target molecules such as biomarkers in various biological samples, such as chromogenic immunohistochemical (IHC) detection in situ by using bright field light microscope. | 09-04-2008 |
20080279946 | METHODS AND COMPOSITIONS FOR INCREASING INFRARED ABSORPTIVITY OF A TARGET - Disclosed herein are compositions and methods for increasing the infrared absorptivity of a therapeutic target. Also disclosed are methods for detecting or ablating a therapeutic target that include providing a nanoparticle composition for increasing the infrared absorptivity of the therapeutic target. Subsequently, the therapeutic target having increased infrared absorptivity is exposed to a therapeutically effective dose of infrared irradiation to effect its detection or ablation. In addition, a method is disclosed for treating a subject suffering from a tumor by providing to the tumor a nanoparticle composition for increasing its infrared absorptivity. The tumor having increased infrared absorptivity is then heated by exposing it to a therapeutically effective dose of infrared irradiation. | 11-13-2008 |
20080318249 | Methods and reagents to increase the sensitivity of enzyme metallographic detection - A test agent includes a composite probe having at least one nanoparticle having multiple metal atoms, a directing agent, and an enzyme. The directing agent attaches the probe to a target in a test sample. The test sample and bound probe are then treated with an enzyme substrate. A method of detecting a target in a test sample includes exposing the test sample to the probe, then treating the test sample with an enhancement or development solution to deposit at least one of a fluorophore, a chromogen, or a metal. | 12-25-2008 |
