[Establishment of a recombinase-aided isothermal amplification technique to detect specific gene fragments].

Objective: To establish a novel method for the detection of specific gene fragments by recombinase aided isothermal amplification (RAA).

Methods: The gene fragment SjG28 of was selected as the target gene fragment to be detected, and the primers were designed according to the mechanism of RAA reaction. The reaction of isothermal amplification of was established and optimized.

The Antibacterial Activity of Ta-doped ZnO Nanoparticles.

A novel photocatalyst of Ta-doped ZnO nanoparticles was prepared by a modified Pechini-type method. The antimicrobial study of Ta-doped ZnO nanoparticles on several bacteria of Gram-positive Bacillus subtilis (B. subtilis) and Staphylococcus aureus (S.
