Patent number: 8394391Abstract: A drug delivery vehicle for targeted delivery of a drug mimics viral properties of size, capsid-like protein capsule, cell-specific entry, toxin release, destruction of infected cells, and migration to neighboring cells. This vehicle, termed a virogel, contains a hydrophobic polymeric core, a hydrophilic inner shell, a hydrophilic outer shell, and a ligand. An illustrative drug-loaded virogel includes poly(L-histidine-co-phenylalanine) as the core, doxorubicin loaded in the core, polyethylene glycol as the inner shell, bovine serum albumin as the outer shell, and folic acid as the ligand.Type: GrantFiled: August 31, 2007Date of Patent: March 12, 2013Assignee: University of Utah Research FoundationInventors: You Han Bae, Eun Seong Lee, Dongin Kim, Yu Seok Youn, Kyung Taek Oh

Patent number: 8263664Abstract: Mixed micelles containing poly(L-histidine-co-phenylalanine)-poly(ethylene glycol) block copolymer and poly(L-lactic acid)-poly(ethylene glycol) block copolymer are a pH-sensitive drug carrier that release the drug in an acidic microenvironment, but not in the blood. Since the microenvironment of solid tumors is acidic, these mixed micelles are useful for treating cancer, including those cancers exhibiting multidrug resistance. Targeting ligands, such as folate, can also be attached to the mixed micelles for enhancing drug delivery into cells. Methods of treating a warm-blooded animal with such a drug are disclosed.Type: GrantFiled: June 18, 2009Date of Patent: September 11, 2012Assignee: University of Utah Research FoundationInventors: Dongin Kim, Zhonggao Gao, Eun Seong Lee, You Han Bae

Patent number: 8064053Abstract: The present invention relates to a 3-color multiplex CARS spectrometer. In the 3-color multiplex CARS spectrometer, Raman resonance is achieved for multiple molecular vibrations of a sample by the combination of a short-wavelength pump beam generated by a broadband laser light source and a long-wavelength Stokes beam generated by a stable laser light source, and another short-wavelength laser beam having a narrow linewidth is then introduced separately to serve as a probe beam that interacts with the laser-driven sample, thereby generating CARS spectral signals whose wavelength components can be resolved. Accordingly, the 3-color multiplex CARS spectrometer solves problem of the conventional 2-color multiplex CARS spectroscopy in which the wavelength decomposition of CARS signals, necessary for high spectral resolution, is not possible with broadband pump light causing the CARS spectrum distortion.Type: GrantFiled: December 29, 2008Date of Patent: November 22, 2011Assignee: Korea Research Institute of Standards and ScienceInventors: Jae Yong Lee, Eun Seong Lee, Dae Won Moon
