Abstract: Disclosed herein are gelatin particles that have been crosslinked without using a crosslinking agent and are easily taken up by cells themselves, and a method for producing such gelatin particles. The gelatin particles are made of self-crosslinked gelatin and have a particle diameter of 0.010 μm or more but 5.0 μm or less. The gelatin particles can be produced by discharging droplets of a liquid containing melted gelatin into air in a heating tube or a drying chamber and drying the droplets to form the gelatin into particles under conditions where a difference between the temperature in the heating tube or the drying chamber and the temperature of the liquid is 235° C. or less and further by crosslinking the gelatin forming the particles.

Abstract: The purpose of the present invention is to provide: a method which is for assessing the differentiation state of cells and by which the differentiation state of a wide variety of cells can be assessed; and gelatin nanoparticles which can be used in said method. The purpose is achieved by a method for assessing the differentiation state of cells, the method comprising a step for observing the expression of pyruvate dehydrogenase kinase 1 (PDK1) or mRNA (Pdk1) encoding pyruvate dehydrogenase kinase 1 in cells. Said method can be carried out by using gelatin nanoparticles which are used for assessing the differentiation state of cells and carry a probe capable of detecting Pdk1 or PDK1.

Abstract: The present invention addresses the problem of providing spherical zinc oxide particles which have an average particle diameter within a specific range, have excellent monodispersity, and have a high plasmon resonance intensity. Also provided are a process for producing the spherical zinc oxide particles and a plasmon sensor chip obtained using the spherical zinc oxide particles, the chip having high sensitivity and being reduced in angle dependence during measurement. The spherical zinc oxide particles have been doped with one or more metallic elements selected from the group consisting of gallium (Ga), europium (Eu), cerium (Ce), praseodymium (Pr), samarium (Sm), gadolinium (Gd), terbium (Tb), neodymium (Nd), and ytterbium (Yb), have an average particle diameter within the range of 50 to 5,000 nm, and have a variation coefficient in particle diameter distribution within the range of 1.0 to 10%.
