Abstract: The disclosure provides a kit for detecting microsatellite instability and a method therefor. The kit includes a negative control, a plurality of qPCR reaction solutions, a qPCR premix and a sterile enzyme-free water; the plurality of qPCR reaction solutions includes 6 pairs of upstream primers and downstream primers of which the MSI mutation site is amplified, and a reference probe for the internal reference and a detection probe for the mutation site. The difference between the amplification of the gene and the gene at the mutation site of the samples and the negative control is used to detect the microsatellite instability. The method and kit as provided is easy and simple without the need of normal tissues being a control, and the need to open the cap. By doing so, aerosol pollution is avoided and sample supplies are conserved.

Abstract: The present disclosure provides for metal nanoparticles, such as gold nanoparticles that have six pointed areas so that the metal nanoparticle resembles a six-pointed star. The distance from opposing points of the six-pointed star is about 400 to 480 nanometers. The present disclosure also provides for a method of making the nanoparticle, where in an aspect, the method is a light-driven synthesis.

Abstract: A light-guide type display device (1) according to the present disclosure includes: a light guide plate (20) that optically guides an image to a pupil of a viewer; and a support member (10) that supports the light guide plate (20) and is provided with two fixing members (105). The light guide plate (20) includes a first opening section (203) that has a first opening having a long axis and a short axis, and a second opening section (205) that has a second opening having a shape different from that of the first opening and located on a line that passes through the first opening section (203) and that is parallel to a long-axis direction of the first opening section (203). Each of the two fixing members (105) is inserted into a corresponding one of the first opening section (203) and the second opening section (205).
