An electromagnetic radiation pulse (e.g., ultraviolet pulse)-measuring apparatus having a beam-splitter that splits the pulse into two sub-pulses, where spectrally-sheared up-converted replicas of the pulse are produced; useful for telecommunication, material processing and biological imaging.

A method of preparing polymer nanoparticles for biological imaging, involving producing a mixture of acrylate, polymerization initiator that is activated by microwave irradiation, cross-linker that creates intra-particle cross-links during polymerization and water based solvent.

An optical beam with an inhomogeneous polarization state in which polarization rotates in a continuous and counterclockwise manner while traversing a circular path around a beam axis in a clockwise direction; used for optical inspection, lithography and biological imaging, such as confocal microscopy for dark-field confocal inspection of biological samples and spectroscopic imaging.

A novel chromophore used as a photo polymerization initiator for a composition used for biological imaging.

A method of producing nanoparticles as micro-reactor vessels by combining two reactant mixtures and flash precipitating under conditions to react the polymeric reactants and form precipitated nanoparticles comprising a block and/or graft copolymer.

A biologically functional fluorescent magnetic nanometer particle and its preparation method and application. The particle has core-shell structure, including fluorescent material and magnetic material of the kernel layer; the shell layer formed by fluorescent transparent material; and the modified layer above the shell layer surface with an organic functional group.

A nanoparticles quantifying and/or detecting method for in vitro diagnosis, etc., involving illuminating through an upper or lower surface of a flat solid support, made of glass, using a white light source or polychromatic light to illuminate the nanoparticles present on the upper surface.

A dynamic focusing apparatus that has an annular transducer, transmitter and receiver. The annular transducer includes different frequency responses at different surface positions and adjusts frequency characteristics of a transmit waveform or receive filter; used for ultrasonic imaging, for example, in biological or medical imaging and non-destructive testing.

A method for using dynamic digit model to detect CT angiography reconstruction algorithm performance.

A near-field imaging apparatus useful in a system for collecting image data of macromolecules, comprises a near-field microscope and a precision optical probe coupled to the microscope for noninvasively imaging inside a cell without destruction.
