The present invention discloses a method for separating nanoparticles with a controlled number of active groups is disclosed. First, a plurality of nanoparticles are provided, wherein the surface of the nanoparticle comprises a plurality of first active groups. Next, a plurality of functional ligands are provided, wherein the functional ligand comprises at least one second active group and at least one third active group. Then, a binding process is performed to bind the nanoparticle with the functional ligand, wherein the first active group connects with the second active group. After the binding process, a separation process is performed to isolate a plurality of nanoparticles with a controlled number of the third active groups. The controlled number is integers from 0 to 10.

The present invention discloses a tunable fluorescent gold nanocluster. The tunable fluorescent gold nanocluster is formed by mixing gold trichloride (AuCl) with toluene solvent without reductant. The tunable fluorescent gold nanocluster emits blue fluorescence that can be red shifted through ultrasonic vibration. The spectral region of the tunable fluorescent gold nanocluster is from 400 nm to 550 nm.

The present invention discloses a system for cultivating cells, wherein the system comprises a bioreactor, a pump, and an electromagnetic module comprising a coil and an electromagnetic stimulator. The cells are disposed within the bioreactor. The pump, connected to the bioreactor, is used to drive gas into the bioreactor, so as to ensure a sufficient gas supply for the cells. Additionally, the electromagnetic stimulator, connected to the coil, is used to provide a plurality of first signals, and the first signals are transported to the coil. Then the induced electromagnetic field is produced by the coil, whereby the induced electromagnetic field is applied on the cells within the bioreactor. Moreover, this invention also discloses the method for cultivating cells.
