Spatial control of chemical reactions, with micro- and nanometer scale resolution, has important consequences for one pot synthesis, engineering complex reactions, developmental biology, cellular biochemistry and emergent behavior. We review synthetic methods to engineer this spatial control using chemical diffusion from spherical particles, shells and polyhedra. We discuss systems that enable both isotropic and anisotropic chemical release from isolated and arrayed particles to create inhomogeneous and spatially patterned chemical fields. In addition to such finite chemical sources, we also discuss spatial control enabled with laminar flow in 2D and 3D microfluidic networks. Throughout the paper, we highlight applications of spatially controlled chemistry in chemical kinetics, reaction-diffusion systems, chemotaxis and morphogenesis.
具有微米和纳米级分辨率的化学反应空间控制，对于一锅合成、复杂反应工程、发育生物学、细胞生物化学和涌现行为具有重要意义。我们综述了利用球形颗粒、壳层和多面体的化学扩散来实现这种空间控制的合成方法。我们讨论了能够使孤立颗粒和阵列颗粒实现各向同性和各向异性化学释放，从而创建不均匀和空间图案化化学场的系统。除了这种有限的化学源，我们还讨论了二维和三维微流体网络中层流实现的空间控制。在整篇论文中，我们重点介绍了空间控制化学在化学动力学、反应扩散系统、趋化性和形态发生中的应用。
