Abstract:
A tunable coherent light source includes a pump laser for generating a pump beam and an optical parametric oscillator including a crystal exhibiting an output curve for a pump beam of a defined wavelength, the output curve defining wavelengths of signal and idler outputs based on periodically poled grating periods of the crystal. The crystal has a plurality of segments associated with a plurality of grating periods of the output curve, each segment of the plurality of segments having a different crystal structure. At least one of the plurality of segments comprises a crystal structure combining at least two of the grating periods A heating device heats the crystal to an elevated operating temperature and is adjustable for adjusting the output wavelengths of each of the segments.

Abstract:
A method of cross-linking a peptide to form a homopolymer of the peptide, to immobilize the peptide on a solid phase and to enhance antigenicity of the peptide is disclosed. The method comprises the steps of preparing a fusion peptide by incorporating a cross-linking segment including a tetrapeptide sequence Q-X-K-(S/T) (SEQ ID NO: 15) into the peptide and cross-linking the peptide by a glutaminase.

Abstract:
A system for measurement of the height, angle and their variations of the surface of an object comprises a measurement module and an astigmatic optical path mechanism. The optical path mechanism makes a laser beam pass a lens assembly and focus on an object. The reflected light passes the lens assembly and an astigmatic lens, arriving at the photo sensor assembly, forming a light spot thereon. The translational displacements of the object are measured by the variations in shape of the light spot on the photo sensors. The angular displacements of the object are measured accordingly by the movement of the light spot on the photo sensors.
Abstract:
The microarray biochemical reaction device of this invention integrates microfluidic trenches with a microarray to form a serpentine microchannel passing through all DNA probes provided in the microarray. A sample solution is introduced into the microchannel and scrambled into discrete plugs to induce droplet mixing. The discrete plugs are then shuttled through the entire microchannel (shuttle hybridization), sweeping over DNA probes to perform hybridization. Using chaotic mixing of droplets, the hybridization efficiency is enhanced and reaction time for hybridization is shortened. During shuttling, the plugs are thoroughly mixed by the natural re-circulating flows. Method for the preparation of the microarray biochemical reaction device is also disclosed.
