Abstract: The present invention discloses a rapid dot matrix micro-nano impact indentation testing system. The rapid dot matrix micro-nano impact indentation testing system comprises a three-dimensional electric positioning module, wherein the three-dimensional electric positioning module comprises an XY translation stage and a Z-axis lifting stage; a dot matrix impact indentation module, wherein the dot matrix impact indentation module comprises a three-degree-of-freedom piezoelectric platform arranged on the Z-axis lifting stage, one surface of the three-degree-of-freedom piezoelectric platform is provided with a piezoelectric ceramic actuator, and one end of the piezoelectric ceramic actuator is connected to an indenter; a clamp, wherein the clamp clamps a test piece, and the test piece faces the indenter; and an imaging module, wherein the imaging module comprises a microscope lens.

Abstract: An optical imaging system (1) is configured for photographing a sample and includes a lighting module (11) and an imaging module (15). The lighting module (11) is configured for outputting excitation light, the excitation light is configured to excite the sample to generate excited light, the imaging module (15) comprises a time delay integration line scan camera (151), the time delay integration line scan camera (151) is configured to record the excited light. A biochemical substance detection system using the optical imaging system (1) is also provided, improving the detection flux.

Abstract: Embodiments of the disclosure include methods and systems for nucleic acid sequencing that may include an objective coupled to an actuator, wherein the actuator is configured to move the objective over a surface of a substrate. In some embodiments, a droplet may be disposed on the surface of the substrate, and the droplet may be moved along with the objective. The distal end of the objective may include a material that provides a higher friction against the droplet than a material of the surface of the substrate. In some embodiments, the distal end of the objective may be immersed in a fluid as it is moved over the surface of the substrate. The substrate may include vertical walls within a region to retain the fluid.
