Semiconductor nanocrystals are tiny fluorescent particles that have recently made a major impact in the biological and medical sciences by enabling high-sensitivity imaging of biomolecules, cells, and tissues. Spherical quantum dots are the prototypical material for these applications but recent synthetic advances have led to a diverse range of nanostructures with controllable sizes, shapes, and materials combinations that offer new dimensions of optical and structural tunability. Uniform anisotropic shapes with linearly polarized light emission allow optical imaging of particle orientation, planar structures have large flexible surfaces and ultra-narrow electronic transitions, and compact nanoparticles have enhanced diffusion in crowded biological environments. These properties are providing unique opportunities to probe basic biological processes, cellular structures, and organismal physiology.

半导体纳米晶体的奇异形状:生物成像中的新兴应用。

半导体纳米晶体是微小的荧光颗粒,最近通过实现生物分子、细胞和组织的高灵敏度成像对生物和医学科学产生了重大影响。球形量子点是这些应用的原型材料,但最近的合成进展导致了各种尺寸、形状和材料组合可控的纳米结构,这些纳米结构提供了新的光学和结构可调性维度。具有线性偏振光发射的均匀各向异性形状允许对粒子取向进行光学成像,平面结构具有大的柔性表面和超窄电子跃迁,紧凑的纳米粒子在拥挤的生物环境中增强了扩散。
