摘要： To provide a technology capable of stabilizing droplets.
Provided is a particle isolation device or the like including: a vibration unit that applies vibration to a fluid containing sheath liquid by supplying a driving voltage based on each of a plurality of frequencies; an imaging unit that acquires, at a position where the fluid is formed into droplets through the vibration, an image of the fluid and each of the droplets; a liquid temperature control unit that controls a liquid temperature of the sheath liquid; and a frequency control unit that acquires data regarding a state of the droplet at each of the frequencies per liquid temperature of the sheath liquid from the image captured by the imaging unit, and controls the frequency of the driving voltage on the basis of a variation in the data accompanying a change in the liquid temperature of the sheath liquid.

摘要： Provided is a technology for increasing accuracy of a technology which optically detects characteristics of each of particles contained in fluid and analyzes or isolates the detected particles.
Provided is a particle detection device including a light applying unit that applies excitation light to a particle contained in fluid, a light detection unit that detects light emitted by application of the excitation light, and an excitation light detection unit that has an imaging element that detects the excitation light applied to the particle. The light applying unit of the particle detection device according to the present technology may be configured to apply multiple rays of excitation light having different wavelengths from different positions in a flow direction of the fluid. In this case, the excitation light detection unit can detect position information associated with the multiple rays of excitation light.
