    摘要： The present invention provides a fullerene suspension and a method for producing a fullerene suspension having high dispersion stability without any chemical compound. Also, the fullerene suspension and its producing method makes it possible to be applied in various fields including the field of medical and pharmaceutical science and the field of foods and environment, in which the fullerene suspension obtained by the prior methods had not been applied. The fullerene is ground to form nanoparticles by irradiating a fullerene in a poor solvent with a laser. The pulse laser having a width of several-ten femtoseconds to several-hundred nanoseconds is appropriately applied.

    摘要： The present invention relates to a process for producing high-quality crystals of protein or organic substances easily and efficiently. A solution of protein or an organic substance is prepared and then is cooled slowly to be supersaturated to a low degree. This supersaturated solution is irradiated with a femtosecond laser 10. A local explosion phenomenon occurs at the focal point of the laser and thereby a crystalline nucleus is generated. A high-quality crystal is obtained when a crystal is grown on the crystalline nucleus over a long period of time. The femtosecond laser to be used herein can be a titanium:sapphire laser having a wavelength of 800 nm, a duration of 120 fs, a frequency of 1 kHz, and an output of 400 mW.

    摘要： A method of spectrometry is disclosed for measuring transient absorbance and transient absorption spectrum of a substance to be measured at interfaces in liquid phase of particulates containing a fluorescent pigment and the substance to be measured by the utilization of optical resonance phenomenon. An apparatus for carrying out the method is also disclosed and comprises: (a) a pulse laser oscillator for exciting the fluorescent pigment and the substance to be measured, respectively; (b) an optical delay device for causing delay of any one of pulse laser beams of two kinds of wavelengths generated by the pulse laser oscillator; (c) a microscope system for condensing laser beams generated by the pulse laser oscillator and irradiating the condensed beams to the sample; and (d) a detector for detecting light emission of the sample. According to the method of the present invention, it is possible to measure transient absorbance and transient absorption spectrum at a high sensitivity even when particulates containing the substance to be measured in liquid phase are present.
