Portable and sensitive quantitative detection of DNA based on personal glucose meters and isothermal circular strand-displacement polymerization reaction.

A portable and sensitive quantitative DNA detection method based on personal glucose meters and isothermal circular strand-displacement polymerization reaction was developed. The target DNA triggered target recycling process, which opened capture DNA. The released target then found another capture DNA to trigger another polymerization cycle, which was repeated for many rounds, resulting in the multiplication of the DNA-invertase conjugation on the surface of Streptavidin-MNBs.

Portable and sensitive quantitative detection of DNA using personal glucose meters and exonuclease III-assisted signal amplification.

A portable and sensitive quantitative DNA detection method using personal glucose meters (PGMs) and Exonuclease III-assisted signal amplification was developed. In the presence of target DNA, a target recycling process that can release target and linker DNA was obtained. The released linker DNA was used to link capture DNA on magnetic beads and the DNA invertase.

[Microscopic identification and UV-Vis spectrum identification on Sapium sebiferum].

Objective: To study the microscopic and UV-Vis spectrum characteristic of Sapium sebiferum.

Methods: The microscopic identification and UV-Vis spectrum identification were adopted.

Results: There were cluster crystals in cortical cells of roots and stems and parenchyma cells of the leaves.
