The present invention provides a target substance transfer method, a crystal production method, a composition production method, and a target substance transfer device, which allow the concentration of a target substance to be increased easily and effectively. The target substance transfer method is a method for transferring a target substancefrom a first phasethat is a liquid or solid phase containing the target substanceto a second phaseincluding: a phase approximation step of bringing the first phaseand the second phaseinto close proximity; and a bubble collapse step of forming bubbles in the vicinity of a boundary between the first phaseand the second phaseand then causing the bubbles to collapse.

Provided are a method for observing protein crystal, wherein the growth process of the protein crystals is nondestructively and three-dimensionally monitored on a real-time basis and the growth of the crystals is controlled at a high accuracy to thereby enable the formation of single crystals having good qualities, which comprises observing the protein crystals, said protein crystals having been produced by a crystallization method using a gel, by an OCT measurement using light emitted from an ultrawideband light source; a method for observing protein crystals wherein the ultrawideband light source is an ultrawideband supercontinuum light source; a method for observing protein crystals wherein the center wavelength of the light emitted from the ultrawideband supercontinuum light source is a 0.8 &#x3bc;m band; and a method for observing protein crystals wherein the monitoring of the protein crystals is a monitoring by an in situ measurement.
