Abstract: An instrument for biological analysis includes a base, an excitation source, an optical sensor, an excitation optical system, and an emission optical system. The base is configured to receive a sample holder comprising a plurality of biological samples. The optical sensor is configured to receive emissions from the biological samples in response to the excitation source. The instrument may additionally include a sensor lens enclosed by a lens case and a focusing mechanism including a gear that engages the lens case, the focusing mechanism being accessible outside the enclosure for adjusting a focus. The may instrument further include a sensor aperture dispose along an emission optical path and a blocking structure disposed to cooperate with the sensor aperture such that none of the reflected radiation from an illuminated surface near the sample holder is received by the optical sensor that does not also reflect off another surface of the instrument.

Abstract: Some embodiments of the disclosure provide a polymer film used for a biosensor. The polymer film has a three-dimensional network structure formed by a natural high-molecular polymer and a synthetic high-molecular polymer by a plurality of crosslinking modes. The three-dimensional network structure includes a chemically crosslinked network and a reversible physically crosslinked network, the chemically crosslinked network being formed by covalent bond crosslinking and the reversible physically crosslinked network being formed by ionic bond crosslinking. The chemically crosslinked network has covalent bond crosslinking between the synthetic high-molecular polymers and covalent bond crosslinking between the natural high-molecular polymer and the synthetic high-molecular polymer. The physically crosslinked network has ionic bond crosslinking between natural high-molecular polymers.

Abstract: Some embodiments of the disclosure provide an applicator for applying a medical instrument to a host. In some examples, the applicator includes a housing, an auxiliary mechanism, a first drive mechanism, and a second drive mechanism. The auxiliary mechanism includes a moving body movable with respect to the housing. A receiving portion is provided to the moving body and configured to receive and accommodate the medical instrument. A puncture member is configured to be movable with respect to the receiving portion. The first drive mechanism is configured to act on the moving body toward a proximal end. The second drive mechanism is configured to act on the puncture member toward a distal end. When released, the moving body is driven toward the proximal end by the first drive mechanism to place the medical instrument received in the receiving portion at least partially subcutaneously in the host.

Abstract: Some embodiments of the disclosure describe a batch coating apparatus. In some examples, the batch coating apparatus includes a fixing mechanism, a liquid holding mechanism, a liquid injection mechanism and a control device. The fixing mechanism includes a plurality of fixing portions for fixing work-pieces to be coated. The liquid holding mechanism includes a plurality of liquid tanks arranged side by side. The liquid injection mechanism includes a liquid storage portion and an infusion portion. The control device is configured to control at least one of a relative movement between the fixing mechanism and the liquid holding mechanism and a relative movement between the liquid holding mechanism and the liquid injection mechanism. The control device is configured to control the liquid injection mechanism to supply the coating liquid via the infusion portion.

Abstract: Some embodiments of the disclosure describe an evaluation system based on analyte data including a memory storing a program, a display, and a processor. In some examples, the processor is configured to: receive analyte data during a predetermined time period from an object to be tested, acquire a plurality of analyte indicators different from each other based on the analyte data, normalize the plurality of analyte indicators to a predetermined range to acquire a plurality of normalized analyte indicators, plot a polygon pattern corresponding to the analyte data during the first time period as a target polygon pattern, plot a polygon pattern corresponding to the analyte data during the second time period as a reference polygon pattern, and take a line segment between a vertex and a center point as an axis, and display the target polygon pattern and the reference polygon pattern.
