就象雕刻师一点点地加粘土来制作雕像一样，科学家们也尝试着一点点地用纳米级的粒子来制造新的材料。现在，有二个研究组已经找到一种制造这种新材料的方法：他们用DNA将一串小金珠连接了起来，结果形成由无机粒子和有机分子组成的混合物。这些混合物在生物检测和生物电子学上 Just as carvers make clay statues a little bit, scientists try to make new materials a bit with nanoscale particles. Now two research groups have found a way to make this new material: They connect small strings of gold beads with DNA, resulting in a mixture of inorganic particles and organic molecules. These mixtures are in bioassays and bioelectronics
