Dyy 6c electrophoresis system

Ferric chloride hexahydrate (FeCl 3 Raman spectra were collected with the Beda Teck Raman spectrometer (TacticlD). Bacterial DNA extraction kit was used for bacterial DNA extraction (Sangon). Agarose gel electrophoresis of SEA was measured by DYY-6C Electrophoresis system (Bio-Rad). The gel imaging system is Tieneng Gel Imager (Tanon). Transmission electron microscopy (TEM) imaging of AuNP, Au@Ag nanoparticles, and magnetic nanoparticles were performed using JEM-2100 transmission electron microscopy (JEOL Ltd.). A blood blender for magnetic bead attachment to streptavidin was purchased from Xingkang Medical Appliance Co. The zeta potential and dynamic light scattering data of magnetic beads, streptavidin-modified magnetic beads, and streptavidin-modified magnetic beads bound to DNA were measured by a Zetasizer (Nano-Z).

A multifunctional reader Varioskan LUX microplate was obtained from Thermo Fisher Scientific Company. In addition, a 96-well black polystyrene plate and 96well transparent microtiter plate were purchased from Corning Co. The refrigerated centrifuge was supplied by Eppendorf. The particle size of the QD-SA complex and the zeta potential of BT-PLL were measured by a Zetasizer Nano ZS90. Agarose gel electrophoresis of the QD-SA image was performed in a Chemi Doc MP imaging system (Bio-Rad). Transmission electron microscopy (TEM) images of the QD and QD-SA were obtained by the JEM-2100 transmission electron microscope (JEOL Ltd.). Agarose gel electrophoresis of QD-SA was measured by DYY-6C Electrophoresis system (Bio-Rad).
