The present invention is concerned with a system of delivering particles of nano-scale into mammalian cells with a diameter of 50 &#x3bc;m or less. The system has a container containing the mammalian cells, the particles, a pressure-exerting member for generating transient apertures of substantially 1-200 nm on surface of the cells, a magnetic mechanism configured to generate a magnetic force to act on the pressure-exerting member thus to move the pressure exerting member, a control mechanism for effecting movement of the pressure-exerting member in a predetermined motion pattern, a measuring mechanism configured to indicate magnitude of pressure exerted on surface of the mammalian cells, and a monitoring mechanism.

System and method for delivery of substance into mammalian cells

The present invention is concerned with a system for fusion at least two cells. The system has an optical tweezers system for generating moving optical traps for manipulating the cells, an optical scissors system for cutting cell membrane of the cells and inducing fusion of the cells, an incubation system for providing cell culture in which the cells suspend and cell culture environment for the cells, and a visual detection system allowing visual monitoring of the cells undergoing fusion.
