Abstract: A detection device, including a light-emitting component, a light-detecting component, at least one reflective optical film element, and a control unit, is provided. The light-emitting component is used for providing an excitation beam, wherein a part of the excitation beam whose dominant wavelength falls within an excitation wavelength band generates a fluorescence beam after passing through a test specimen. The light-detecting component is used for receiving a part of the fluorescence beam whose dominant wavelength falls within a detection wavelength band. The control unit is coupled to the at least one reflective optical film element. The control unit controls the at least one reflective optical film element to filter out a part of a wavelength band of an incident beam.

Abstract: The invention relates to a microcarrier, comprising a continuous medium of a biocompatible polymer for culturing cells and having a three-dimensional scaffold architecture delineated peripherally by a continuous outer wall, in which spherical macropores are stacked to one another and interconnected by connecting pores. The continuous outer wall is formed with exposure pores at positions where it is in contact with the macropores, through which the interior of the microcarrier may be in fluid communication with the ambient culture medium. The microcarrier herein is produced by cast-molding and, therefore, has a continuous outer wall which provides additional mechanical strength while maintaining high porosity. The microcarrier thus produced is configured in the form of a basic geometrical body. The invention further relates to a cast-molding process for producing the microcarrier.

Abstract: A fluid-drive device includes a base, a fluid container, a pressing mechanism, and a rotation mechanism. The fluid container is disposed on the base. The pressing mechanism is disposed on the base, and configured to press the fluid container. The rotation mechanism is connected to the pressing mechanism. The pressing mechanism presses the fluid container by rotating the rotation mechanism. The fluid-drive device may guide the flow of the detection fluid in the fluid container in a non-contact manner to reduce the contamination of the fluid specimen and increase the reliability of the detection.

Abstract: A detection device includes a light emitting element, an accommodation frame, a light detector, and a movable light splitter. The light emitting element provides an excitation beam. The accommodation frame accommodates an object under test, and a portion of the excitation beam whose dominant light emitting wavelength falls within a first waveband range forms a fluorescent beam after passing through the object under test. The light detector receives a portion of the fluorescent beam whose dominant light emitting wavelength falls within a second waveband range. The movable light splitter forms a plurality of sub-beams from an incident beam. The sub-beams have respectively different dominant light emitting wavelengths and exits at different emitting angles. The incident beam is at least one of the excitation beam and the fluorescent beam.

Abstract: A cable-arrangement structure includes two device bodies and a cable. The two device bodies are rotatably connected relative to a rotation axis. The cable has two fixed segments and a connecting segment connecting the two fixed segments. The two fixed segments are fixedly disposed on the two device bodies respectively. The connecting segment is movably disposed surrounding the rotation axis. An electrical apparatus includes the above cable-arrangement; therein, the cable electrically connects the two device bodies. When the two device bodies rotate relatively, by the movability characteristic of the connecting segment, the cable can be free of being tensed or twisted and will not hook other components, and the electrical connection of the two device bodies can be maintained.

Abstract: The invention relates to methods for producing three-dimensional ordered porous microstructures. Particularly, the invention involves facilitating the self-assembling of particles, thereby forming a three-dimensional ordered microstructure composed of a close-packing of the particles. The invention further involves forming a sacrificial layer between the three-dimensional ordered microstructure and the substrate. An inverse opal material is then filled into the interstitial voids among the particles. The particles are removed after the inverse opal material is cured, thereby producing a three-dimensional ordered porous microstructure with excellent integrity and high reproducibility.

Abstract: The present invention provides a method and apparatus for amplifying a nucleic acid sequence by polymerase chain reaction (PCR). The method comprises placing a PCR sample in a container which is heated by only a single heat source that provides a high temperature for denaturation in the bottom of the PCR sample, while annealing and extension automatically occur in different regions of the PCR sample due to the convection induced by a temperature gradient descending from the bottom of the PCR sample to the surface of the PCR sample.
