Abstract: An immune molecule virus particle detection kit is provided. A monoclonal antibody of a virus envelope antigen is modified with biotin, magnetic beads are coupled with streptavidin, and the biotin-modified monoclonal antibody is incubated with a virus-containing solution to form a complex with virus particles or antigens, and then the streptavidin-coupled magnetic beads are added for incubation. The streptavidin on the magnetic beads binds with the biotin-modified monoclonal antibody with high specificity and affinity, and then specifically captures the virus particles with envelopes. After separating a supernatant through a magnetic separator, complete viral particles, empty-shell viruses, and free envelope antigens can be separated from other virus components, and the magnetic bead conjugates can be qualitatively or quantitatively detected through polymerase chain reaction (PCR) amplification.

Abstract: A sexual stimulation device includes a housing, a suction nozzle, a motor, an eccentric rod, and a connecting rod. The motor drives the eccentric rod to rotate. The eccentric rod drives the connecting rod to swing left and right to enable a stimulation member to swing left and right. The stimulation member swings left and right to squeeze the air in a space in the suction nozzle to generate an air vortex. The force generated by the air vortex is to perform 360° massage and stimulation on the female erogenous zone. It effectively enhances the user's experience, and it is easier for the user to have an orgasm.
