Abstract: A cell culture device configured for activating, transducing, isolating and/or expanding cells. The cell culture device includes a mixing tank and a rotary control platform. The mixing tank includes a first support, a hollow tank and a cover. The hollow tank is disposed on the first support and has a first opening, a second opening and an accommodating space. The cover covers the second opening and has a first hole, an inlet end and an outlet end. The rotary control platform includes a base, a second support, a rotating gear, an inclination control member and a micro injector. The second support is disposed on the base. The rotating gear is fixed on the first support. The inclination control member has a first part, a second part and a third part. The first part is connected to the rotating gear, and the second part is connected to the first part and the third part. The micro injector extends to the accommodating space through the first hole of the cover.

Abstract: A magnetic separation device includes a sleeve and two fixing portions. The sleeve includes a sleeve body and a hollow portion. The hollow portion penetrates through the sleeve body. The two fixing portions are individually disposed oppositely to a first end and a second end of the sleeve body. Each of the two fixing portions includes a protruding body and a groove. The protruding body is protruded out from an outer surface of the sleeve body, and the groove is disposed at an outer surface of the protruding body.

Abstract: A method for in vitro activation and/or expansion of immune cells is provided, including the steps of: a) providing magnetic particles having multi-protrusive surface modified with at least one type of immuno-inducing substance, in which each magnetic particle includes a copolymer core, a polymer layer, a magnetic substance layer, and a silicon-based layer from the inside to the outside; b) providing a cell solution including at least one type of immune cell in the cell solution; and c) bringing the magnetic particles in contact with the cell solution, in which the at least one type of immuno-inducing substance on the surface of the magnetic particle activates and/or expands the at least one type of immune cell in the cell solution.

Abstract: A detection method of multiple analytes includes the following. A microparticle is provided. The microparticle is coupled with at least one first ligand, and includes a body and a plurality of first protrusions formed on a surface of the body. Next, the microparticle is mixed with a variety of analytes to form a first complex. Thereafter, the first complex is mixed with a variety of second ligands carrying a variety of first labels, such that the variety of second ligands bind to the variety of analytes in the first complex and form a second complex. Lastly, the variety of first labels in the variety of second ligands in the second complex are detected.
