Title:
METHOD FOR SEPARATING AND RECOVERING PARTICLES AND DEVICE FOR SEPARATING AND RECOVERING PARTICLES
Document Type and Number:
Japanese Patent JP2022011213
Kind Code:
A
Abstract:
To provide a method for separating and recovering particles with high efficiency and high throughput, which is possible to inexpensively and easily separate and recover particles having a size of 30 nm to 10 μm, such as exosomes, from a sample solution and to provide a device for separating and recovering particles, which can be suitably used for the method.SOLUTION: The method for separating and recovering particles comprises the steps of: preparing a sample solution containing exosomes; passing the sample solution through a track-etched membrane to collect particles in the sample solution on the track-etched membrane. A device 10 for separating and recovering particles comprises: an upstream chamber 11 for receiving a sample solution containing exosomes; a downstream chamber 12 that communicates with the upstream chamber; and a track-etched membrane 13 for collecting particles in the sample solution, which is arranged between the upstream chamber 11 and the downstream chamber 12 so that the sample solution can be passed from the upstream chamber 11 to the downstream chamber 12.SELECTED DRAWING: Figure 2
