BLUE-COLORED GOLD NANOPARTICLES FOR IMMUNOLOGICAL MEASUREMENT, PROCESS FOR PRODUCTION OF SAME, AND MEASUREMENT METHOD USING SAME |
摘要 |
<p>Gold nanoparticles which comprises organic buffer containing a piperazine ring, gold, and an organic acid having reducing properties and which shows a blue color by visually view when it is dispersed as a colloidal solution, can be produced easily by conducting a nucleus formation step by reacting organic acid containing a piperazine ring with a solution of a first gold salt to form nucleus gold nanoparticles and a growth step by simultaneously adding and reacting a solution of a second gold salt and an organic acid having reducing properties with a solution of the nucleus gold nanoparticle to grow the nucleus gold nanoparticles. The produced gold nanoparticles can be used as labeling particles in an immunological measurement method.</p> |
