| 20090097808 | Fluid waveguide and uses thereof - The invention relates to methods and apparatuses for guiding and emitting electromagnetic radiation from a fluid waveguide. Various methods for changing optical properties (e.g., refractive index, absorption, and fluorescence) and/or physical properties (e.g., magnetic susceptibility, electrical conductivity, and temperature) of either the waveguide core or the cladding, or both, are provided herein. In one embodiment, electromagnetic radiation is guided and/or emitted at multiple distinct wavelengths, including emission in the form of an essentially continuous band, in some cases covering at least 150 nanometers. In another embodiment, methods for splitting a waveguide core and/or the joining of at least two waveguide cores in a waveguide are provided. In yet another embodiment, the invention includes the use of thermal gradients to generate a waveguide and/or to change the properties of waveguides. Embodiments of the waveguides may be used for optical detection or spectroscopic analysis. | 04-16-2009 |
| 20100303119 | Microfluidic Lasers - The present invention generally relates to lasers comprising fluidic channels, such as microfluidic channels. In some instances, the channel contains two or more fluids. The fluids may remain non-mixed within the channel, for example, due to immiscibility and/or laminar flow within the channel. The fluids may be arranged in the channel such that light propagating in a first fluid is prevented by the second fluid from exiting the first fluid, for example, due to differences in the indexes of refraction (e.g., causing internal reflection of the fluid to occur). Thus, in one embodiment, a first fluid may be at least partially surrounded by a second fluid having a second index of refraction lower than the index of refraction of the first fluid. In some embodiments, the fluidic channel is used as a laser, for instance, a dye laser, i.e., a laser created by directing light at a dye to produce coherent light. The dye may be present in one or more fluids within the fluidic channel. The incident light (for example, created by another laser) may be directed at the channel from any angle. In some cases, laser light may be produced in a direction substantially aligned with the longitudinal axis of the channel. In some embodiments, the laser is free of mirrors, prisms, or gratings, or the laser may produce coherent light using a non-resonant photonic pathway. However, in other cases, mirrors, prisms, or gratings may be used to reflect light along the channel to enhance stimulated emission of coherent light. Another aspect of the invention includes optical diffractors, such as prisms or gratings, which can contain a fluid. The optical diffractors, in certain embodiments, are positioned to diffract light, such as coherent light, emanating from the fluidic channel. Still other aspects of the invention provide devices, kits, and methods of making and using such lasers. | 12-02-2010 |

| 20090030257 | Anti-microbial photodynamic therapy - Antimicrobial molecular conjugates for the treatment and prevention of infectious diseases caused by pathogenic microorganisms in human and animals are provided. The key to these conjugates is a special spacer connecting at least one photosensitizer to a microorganism receptor (vector) which in turn binds selectively to the surface of a microorganism bringing about photo-destruction upon irradiation. Spacers having hydrophilic structure such as ethylene glycol units and amino carboxyl end capped ethylene glycol units must be used for linking the vector to the photosensitizer. In a preferred embodiment a spacer would have at least 3 ethylene glycol units and be end capped with a carboxyl group on one end and a amino group at the other end. The present invention effectively works to combat bacterial infection in the real patient-related environments where blood, serum and other body fluids are always present or at least nearby of selected length and structure, in preferred embodiments, are used for linking the vector to the photosensitizer. These conjugate are found to be very effective in combating bacterial infection in the real patient-related environments where blood, serum and other body fluids are always present or a least nearby. A method of use is also provided. | 01-29-2009 |
