The invention relates to a micrometric displacement sensor based on an integrated planar ring-shaped micro cavity and a cantilever beam, which comprises a planar ring-shaped micro cavity, an optical waveguide, a substrate, an incidence fiber connected with the optical waveguide and an emergence fiber connected with the optical waveguide. The planar ring-shaped micro cavity is coupled with the optical phase of the optical waveguide. The micrometric displacement sensor is characterized in that the micrometric displacement sensor also comprises a cantilever beam and a probe; one end of the cantilever beam is connected with the substrate and the other end of the cantilever beam is a free end; the probe is positioned in the middle of the front part of the free end on the lower surface of the cantilever beam, and both the cantilever beam and the probe are formed by etching; and both the planar ring-shaped micro cavity and the optical waveguide are etched on the upper surface of the cantilever beam. The micrometric displacement sensor is made by using a modern MEMS processing technology, can be used in complex magnetic field environments, vacuum environments, can be used for measuring wide range of objects, including the measurement on the surfaces of biological cells as well as the surfaces of metals and non-metals, and has the measuring precision of 10<-4> angstroms.

The invention belongs to the field of forensic DNA examination and analysis and in particular relates to a miniSTR (short tandem repeat) typing kit used for trace degradation of biological samples. The kit adopts ZNA primers instead of traditional DNA primers and simultaneously carries out multiplex amplification on 12 miniSTR loci and a gender recognition locus, wherein the 12 miniSTR loci are D20S1082, D6S474, D12ATA63, D9S1122, D2S1776, D1S1627, D3S4529, D2S441, D4S2364, D3S3053, D17S1301 and D21S11; and the gender recognition locus is Amelogenin. The STR typing kit provided by the invention combines the miniSTR typing technology with ZNA primer amplification, is suitable for the Chinese population and the minority population, is suitable for trace and high degradation of biological samples and has the effect of greatly improving the typing sensitivity and accuracy.

The invention discloses a bimetallic functionalized ZnCo-MOF catalytic material prepared by a one-pot method of dry glue and its preparation method and application. The preparation method comprises the following steps: mixing metal cobalt salt, aromatic carboxylic acid, acetic acid, and metal zinc salt And water is added to the container, mixed and stirred, evaporated to dryness to obtain dry rubber, and then ground into dry rubber powder, the dry rubber powder is subjected to crystallization reaction, and finally the product is purified and dried to obtain bimetallic functionalized ZnCo‑MOF catalytic material. The bimetallic functionalized ZnCo-MOF catalytic material of the present invention is prepared by a dry glue one-pot method, which has fast reaction, simple synthesis method and high yield.
